I’ve installed the 12K hybrid unit earlier this summer and saved about $60 a month with the help of the solar panels. But what blew me away is that since I’m using this for heat instead of natural gas during the cooler temps, I’m on track to save about $200 a month for using less natural gas!
Thanks for this video! A note to potential buyers / users - I have this exact model and spent far longer than I care to admit trying to figure out what ground screw size it uses. As shown at one point in the video, this unit requires two separate ground screws. However, at least mine only came with a single ground screw; the other hole, meant to ground the wire that goes from the unit to your breaker box, is empty. Apparently it's necessary to provide your own... This unit does not use a standard #10-32 ground screw. It actually uses a #8-32 screw. I purchased 3/8" long machine screws (matching the size of common ground screws) and they worked decently well. Another thing to note, when I used the template to place and then cut the 2 1/2" hole with a hole saw, I had two things happen: (1) the hole ended up being just a touch too low, so the bundle of components going through the wall cause the unit to be slightly off level leaning, unfortunately, away from the direction I'd want it to go (I hope it won't be a problem); and (2) the wall cuff flops around in the space and apparently is far too small to fit a 2 1/2" hole. I just had to leave it out (but I'm not concerned because the insulation plus vinyl tape plus painter's tape should provide plenty of protection. Another note, I wish this video had gone into a lot more detail on sealing the hole outside. When the bundle comes through the wall, it has a LOT of fluff and flex in it components. The slit sleeve of insulation surrounding the refrigerant lines compresses but does not hold its compressed position. This helps with shoving it through the wall hole, but then it springs open and somewhat stiffly holds its position. This leads to numerous air gaps inside the sleeve of insulation surrounding the two refrigerant hoses. How should one seal these effectively? It seems like spraying foam into them would balloon the interior portions of the pipe insulation, which could actually result in undermining the seal. Should one use full conduit through the wall and, if so, why isn't this noted in the manual? Yet another note, I wish there were more detail on how to handle the stiff part of the refrigerant hoses attached to the interior unit. It is QUITE STARTLING to physically bend copper lines that are hard wired to the unit, so extreme detail would be super useful. How many times can they handle being bent? If you bend them slightly wrong, what is the best way to guide them into a better position without hurting them? What does it mean to bend them wrong and cause them damage (what does that look like? How should it be handled if it does happen?)? Once they're outside, I assume it's okay to bend them AGAIN toward the direction you want them to go so that they run more flush to the exterior wall instead of sticking straight out like a foot (and since this must be okay to do, how should it be done to minimize the likelihood of damage and reduction in unit performance)? How many bends can they have in them and still work optimally? Should we attempt to never bend them past 90 degrees and keep them to less-sharp angles?
Thank you for your detailed review and valuable insights! Here are answers to your questions: Sealing the hole outside: For sealing the air gaps, using expanding foam can be effective but should be done carefully to avoid over-expansion. Alternatively, using a combination of foam and caulk can help seal the gaps without putting too much pressure on the insulation. Handling refrigerant hoses: Bending the copper lines should be done with caution. They can typically handle a few bends, but it's crucial to avoid sharp angles to prevent kinks. If a line is bent incorrectly, gently guiding it back into place is best. It's safe to bend them again once outside, but always aim for smooth, gradual curves and avoid bending past 90 degrees to maintain optimal performance. We appreciate your feedback so much on these points and will consider incorporating more detailed instructions in our future videos. Your experience highlights important considerations for other buyers, and we’re grateful for your contribution.
@@SignatureSolar Thank you so much for the thoughtful and kind reply, and for the information! I'll be sure to make use of it as I complete my installation. It's very fresh in my mind, so that fueled many of these comments. :)
I have 5 of these in my 3200 sf home in Florida all installed by my neighbors AC company professionally. They have made a massive difference in our ability to remain comfortable even during power outages. My wife now can put on her makeup in the master bath without bitching about the central AC and her makeup melting on her face. Problem solved.
We have a large living room (35' ceiling) that is about 1500 sq.ft. Our main HVAC always struggled to get this room balanced with the rest of the house. The 24,000 BTU unit has worked really well, and the solar helps us run it guilt free. We also have a 16' fan on the ceiling that helps move the air throughout the room. For a large single space this unit is a no brainer.

Can't wait to install the 24k in my new house. It will provide the brunt of my solar HVAC supplemented with a grid tie 4 zone Mitsubishi for rooms and basement. So much cool stuff out there now.
I appreciate the video very much since I'm a big DIY'er and just got the EG4 12k BTU 28.5 Seer2 from you guys and arrived on pallet... Will be ordering the EG4 6000xp and PowerPro in a few months after or maybe sooner depending on the backorder schedule....
Mr. Prowse, have you done a review with tear down of any of the EG4 sealed/waterproof batteries? I might be mistaken, but I believe that James Showalter cut up one of the 100 amp 12 volt versions already and The WIZARD OF (David) POZ did a review on the 48 volt.
🤔 This was an excellent presentation covering theory, design, as well as installation. I would encourage EG4’s engineering department to provide feedback to EG4 to produce 5000 & 9000 BTU Hybrid units (ie DC/AC/Solar) specifically for the RV industry. Due to the flimsy, yet expensive construction of commercial RV’s there is a sizable trend of DIY’s to build custom RV’s based upon Box Cargo Trailers as well as other platforms. The use of mini split units are taking this niche market by storm, both for ease of installation, heating capability, as well as leading to the possible elimination of the need for propane for reasons of logistics, safety, and moisture gain. The solar capability of the EG4 combined perhaps a waste heat recovery unit for producing hot water, when combined with the EG4’s inherent superior efficiency could lead EG4 to “rule the roost” in the RV application area. Since Signature Solar has a strong business relationship with EG4, its engineering department would be the ideal conduit to facilitate this upgrade in portable solar capability. 😎
Thank you for this video. I found it easier to make the electrical connections from the front of the unit BEFORE extending the copper lines out from the back of the unit.
Well made video. The team at signature solar that makes these videos always do a great job. This was direct, thorough, and easy to understand. Thank you.
PLEASE NOTE -- Can you PLEASE make a video on the App itself and explain every feature of the app and it's meaning and what it does and how the features can help. Thank you!!!
I have a shopping history with Signature solar. I have everything I need except a 6000 BTU mini split. Many people are living in converted sheds of well under 200 sq ft so a 9000 BTU is excessive. You're located near a lot of rural areas where we reclusive types could benefit from a system that doesn't have too many BTUs for our home sizes. They exist and have seer ratings as high as 38 but the ones that can likely have your branding are as high as 26.5.
Great question, thank you! While the video was made following the manual, it's important to note that Teflon tape is designed primarily to seal pipe threads in plumbing and gas connections, preventing leaks by keeping liquids and gases from escaping through threaded connections. It is not intended for waterproofing surfaces or patching leaks like traditional waterproof tape. The manual has been updated on page 13, step 7, to state: "...Wrap the joint with waterproof tape to ensure the hoses do not come apart." For waterproofing purposes, tapes specifically designed for that, such as butyl rubber tape or silicone tape, should be used.
This has been a very informative and an excellent step-by-step video! I’m very interested in the hybrid model…may look into it in the upcoming summer. Out of curiosity, is it possible to run the cooling lines through a ceiling/attic space to run outside, or is the back/side wall installation recommended?
Hi @shawnseler7897 Thank you so much! It is possible to run the cooling lines, but it's important to note that routing the drainage line upward into the attic is not advisable, as drainage doesn't work effectively in an upward direction.
I've got an AC/DC12C Mini-split running strictly off solar in Florida. The EG4 is probably better but mine works. The only thing that bothers me is that I am not using my solar on days when it is sunny but not hot enough to run the AC. On hot evenings I want to run it but the sun goes down so I have to use grid power. I have (5) 400-watt panels and was wondering if you had any suggestions on how to add a battery to the system. This would make a great video I think. Thanks!
Hi @lightdepsolutionssolutions4099! Thank you for the feedback! We believe we've identified the part you are inquiring about as a waterproof cable connector for the wires to pass through the hole from inside the unit to the outside? These are not included with the unit which is why it is not demonstrated in the video. However, these can be purchased separately at any hardware store. Please let us know if this is not what you mean by 'waterproof wire clamp'.
I have a question on the line sets. You mentioned they are precharged. Did you mean they are evacuated? The reason I ask is I want to cut the lines sets to fit and flair them and pull a vacuum. If there is refrigerant in the line sets then I need to rethink this. By the way what are your comments about shortening the line sets and then pulling a vacuum? Thanks for your video. Waving to you from down I-30 about 30 minutes from you. All the best.
The included line-sets are indeed pre-charged and cutting is not recommended. Before the pre-filled ones today, the old units had the customer pull a vacuum and put the coolant in their selves. This shouldn't pose a significant problem in terms of technically working - Waving back! You too!
@@SignatureSolar oh so you are saying the line sets have refrigerant in them and not just some inert gas? I just thought it was vacuum and to cut them I would have to flare them and pull vacuum for a short period of time to confirm a good seal. Then and only then would I release the refrigerant from the mini-split by opening the valves. By the way, that is not a huge problem as I have a HVAC installer that has offered to shorten the lines for me. So if I am using the terms incorrectly be patient with me as I am a retired engineer. 🤣 I am thinking about dropping by your office towards the end of September and chat about these particulars. All the best!
Hi @futuresplayer! I hope you're well! We're so sorry about this! We will definitely forward your findings to the manufacturer. Did you get it mounted in the end?
All I want to do is A/C and Heat an 64sqft deer stand only option is 12K??. If that is all I can get it is what it so as I want solar only lol. I truly love the service I have received at Signature Solar.
Hi @rodneyross5282! Thank you so much for your feedback! Our goal is to give the best service to our customers and it's wonderful to hear we are doing just that. I spoke with our design manager a moment ago regarding your deer stand and he had some well-prepared and cost-effective ideas due to his experience in solar and hunting and recommends giving our team a call as he believes there may be a better option than the 12k for this setup.
Please send me an email at engagement@signaturesolar.com including your contact information and any additional details about your ideas and objectives. I will then connect you with a member of our design team, who has already been briefed by their manager on the recommended system for your needs.
Hi @fantome4448 Please reach out to us at engagement@signaturesolar.com with your name and order number so that we can investigate and get answers for you. We are here to help!
The drain pipe is 1.5 meters. The connecting pipe is 5 meters. The maximum line set length depends on your system - [09k/12k = 49ft] [18k system = 66ft] [24k system = 66ft] [36k system = 98ft]
When running, If it becomes cloudy and not enough solar capacity is being generated, does the unit shut off to a point where someone needs to physically turn on from handheld remote. Or when enough solar energy generated returns does it resume cooling on its own?
!!! Make very sure the cardboard template matches the indoor unit! Especially the hole. In this video you see the hoses come out of the unit a few inches from the right side, and the hole in the template matches that location. On my model the hoses are coming out directly against the right side of the unit, and stupid me had already drilled the hole in the location the (wrong) template provided, which was therefore several inches off. I had to very carefully bend the hoses inside the unit to get them to that wrong location, which was a tight bending I would rather not have done. To add insult to injury the hole cover provided was sticking out under the bottom of the unit, preventing it from locking properly into place. I replaced it with a rubber 'flanged spud washer' that I fitted around some PVC pipe that I led through the hole. Another flanged spud washer on the other side made that hole a nice looking tube with no sharp edges. This was an indoor hole from my kitchen area into my laundry room. The 15 feet of hose supplied with the unit was enough to get to the other side where I did the same thing, using a PVC pipe and washers through the outside wall right next to where the unit hangs. I have only 1 small loop in both hoses that I can easily hide indoor behind a closet that does not touch the wall anyway.
We unfortunately cannot advise on the AC side of things but we do recommend reaching out to a certified electrician to address this with you. Grounding is very important for safety!
The maual that comes with it is terrible. Doesn't even tell you how to change the display from Celsius to Fahrenheit. Thank you for sharing that information in the video.
@@SignatureSolar Bummer, I was hoping to be able to use this 12k unit in my travel trailer, but I have only 32” for a super tight fit between some overhead cabinets. Thank you for your prompt response!

It is not advisable to divide a single solar input in this manner because the two units will be unaware of each other's presence. As a result, they may continuously attempt to draw more power from the solar array than it can effectively generate.
My climate (Calif Coastal) wants a heat pump all winter, but only needs a few days of cooling in heat waves. It looks like you dedicate solar panels to the hybrid. Q1: If I have 8 solar panels in series under 380V and under 12A can I wire them to my hybrid and my in solar inverter in parallel so DC output not needed by the hybrid, can flow to the Inverter and still provide become AC power for my house? Q2: if Strategy 1 does not work in real time parallel, can it work by turning the hybrid off in the summer until it's needed. (Then summer solar would go to inverter and house as AC current until hybrid is turned on to take all the solar DC current.)
Our recommendation is to run a single dedicated PV array for the Mini-Splits. This approach ensures optimal performance and efficiency for your system.
I'm so sorry @ColbyBlack, this would be a question for Delta. If there is anything else we can help you with, please don't hesitate to reach back out to us at any time!
Let me ask this another way, if i have L1, L2, a neutral and a ground coming from a 24 kW battery and inverter at 60 hz “AC output socket (120V/240V 30A max.) - Backup UPS Supports 120V/240V 30A max output and 20 ms UPS” Can I take L1 and L2 from the source and connect it to the L1 and L2 in the outside unit, and the ground to ground, and cap off neutral.
The measurements that are listed in the specs to mount this from the ceiling and the floor are for typical 8 foot walls, so that would be different but otherwise, Yes!
If it wired to solar inverter. And you do not want to run it you have to shutdown it yourself. If it on grid it shut it self off due to no power from grid.
@@Tonyinmemphis Say I want it to run only on solar power. Now the sun goes down. Won't it burn out my motor in the pump? Has the amperage drops? You'd think there might be a low amperage shut off. You wouldn't want to stay. The point being, you don't want to stand there and wait for the Sun to start going down and then randomly shut it off. When you think the Ambridge is dropping.
@@chuckb9867 This unit same as all mini splits they run on less amps. This one there showing is a addon for a solar system with battery backup. There could have the amp draw on there site and if unit is 115v or 220v. I do not know what the fail safe is for low power. most inverter's will shut down low power. Being in a stand and open air you need check the filter weekly. Shoot me one lol .
OK. I plan on mounting it in a motorhome with a 78-inch ceiling. How can I mount it 98 1/2 inches off the ground when I only have 78 inches from floor to ceiling? Can I mount it a little closer to the ceiling, say 4 inches, since the ceiling is so low, or must it have the full 6 inches to fit?
@@SignatureSolar The instructions in the manual are contradictory for my application. If I mount it 6 inches from the ceiling, as the manual suggests, I won't have 98 1/2 inches off the floor. If I subtract the 27.6" height of the head unit, I will only be able to mount it 50.4" off the floor, about half of the 98 1/2" that the manual suggests. Is this optimal for my application? If you don't know, is there someone at the factory I could speak to about the install? Thanks.
@@SignatureSolar We don't seem to be communicating. The installation would be in a motorhome. There are no applicable codes for a motorhome. Are you saying that this unit can only be mounted on walls 11ft or higher? Because that is what the manual's specifications suggest if you add up the 6" from the ceiling, 27.6" of the head unit and 98.5 inches it must be mounted off the floor. I guess every house with 8 ft ceilings can't install this unit then. Please re-read my previous posts. Thanks.
Hi @user-lz5pe9df4y The Mini Split doesn't require a specific height from the ground; rather, it should be measured from the ceiling. If you have any other questions or need guidance with install, please do not hesitate to give us a call, we are here to help!
@@SignatureSolar For whatever reason, the manual on page 7 specifies a minimum clearance between the bottom of the indoor unit and the floor as 2.5 meter which is 98.42 inches. This would require 10 foot ceilings.
I have an odd Quick connect on my unit labeled AB With a red and white wire anybody know what that’s for. It’s on it’s in my indoor unit underneath the cover near the terminals
2 months...NO DELIVERY. I ordered in October , during the free shipping special, and STILL.. I DO NOT HAVE the EG4 HYBRID SOLAR 12000 BTU MINI-SPLIT. I was told the shipment came in two weeks ago. mid- December and would be shipped out immediately and NOW... I gotta wait till the end of January they say. You guys are supposed to be one of the best companies. Disappointed Marine here.
Hi @yourmarine9 We are so sorry for the delay! If you'd like to reach out to me at engagement@signaturesolar.com, I can look into your order and see what is causing the delay!
It may be that you don't have enough solar power going to your unit, if you'd like to give us a call, we can troubleshoot with you and see if we can get you up and running properly!
While it's feasible, the risk of drain line leakage in the wall cavity is a concern. Additionally, the stiffness of copper lines makes it challenging to install them within the wall, posing a risk of kinking or damage.
Hi! Thank you! Yes, this is a mistake and has since been corrected in the manual. The most important thing is that it is at least 5.9 inches from the top of the ceiling.

This has been a very informative and an excellent step-by-step video! I’m very interested in the hybrid model…may look into it in the upcoming summer. Out of curiosity, is it possible to run the cooling lines through a ceiling/attic space to run outside, or is the back/side wall installation recommended?
Hi @shawnseler7897 Thank you so much! It is possible to run the cooling lines, but it's important to note that routing the drainage line upward into the attic is not advisable, as drainage doesn't work effectively in an upward direction.
I've got an AC/DC12C Mini-split running strictly off solar in Florida. The EG4 is probably better but mine works. The only thing that bothers me is that I am not using my solar on days when it is sunny but not hot enough to run the AC. On hot evenings I want to run it but the sun goes down so I have to use grid power. I have (5) 400-watt panels and was wondering if you had any suggestions on how to add a battery to the system. This would make a great video I think. Thanks!
Very informative though you forgot the waterproof wire clamp on the outdoor unit.
Hi @lightdepsolutionssolutions4099! Thank you for the feedback! We believe we've identified the part you are inquiring about as a waterproof cable connector for the wires to pass through the hole from inside the unit to the outside? These are not included with the unit which is why it is not demonstrated in the video. However, these can be purchased separately at any hardware store. Please let us know if this is not what you mean by 'waterproof wire clamp'.
@@SignatureSolar that’s what I meant, yes. Thanks for replying.
Glad to help!
are you ever going to come out with ac/dc heatpump unit that has 2 head units to cold 2 differant rooms
Hi @sulleydee2237 - We will forward this feedback to EG4! Thank you!
With the precharged units is there any valves on the indoor unit or is it just on the outdoor one ?
Its just on the outdoor unit.
I have a question on the line sets. You mentioned they are precharged. Did you mean they are evacuated? The reason I ask is I want to cut the lines sets to fit and flair them and pull a vacuum. If there is refrigerant in the line sets then I need to rethink this. By the way what are your comments about shortening the line sets and then pulling a vacuum? Thanks for your video. Waving to you from down I-30 about 30 minutes from you. All the best.
The included line-sets are indeed pre-charged and cutting is not recommended. Before the pre-filled ones today, the old units had the customer pull a vacuum and put the coolant in their selves. This shouldn't pose a significant problem in terms of technically working - Waving back! You too!
@@SignatureSolar oh so you are saying the line sets have refrigerant in them and not just some inert gas? I just thought it was vacuum and to cut them I would have to flare them and pull vacuum for a short period of time to confirm a good seal. Then and only then would I release the refrigerant from the mini-split by opening the valves. By the way, that is not a huge problem as I have a HVAC installer that has offered to shorten the lines for me. So if I am using the terms incorrectly be patient with me as I am a retired engineer. 🤣 I am thinking about dropping by your office towards the end of September and chat about these particulars. All the best!
The templet sent with the 12000 BTU unit is incorrect. I drilled the hole per template and ended up missing about 2 inches.
Hi @futuresplayer! I hope you're well! We're so sorry about this! We will definitely forward your findings to the manufacturer. Did you get it mounted in the end?
Are you guys going to be part of the inflation reduction act rebate program?
Yes it counts
ok nice video and AC system but since this is a DIY unit do i need a city permit or any thing like that??
No, you do not :)
How to size the right unit need
Do you Do length bye width of trailer
Or length bye width bye high
The cargo trailer is 22L x 8w x 7h
You would size by calculating the square foot of the space you are trying to cool. You can find the capacity for each unit in their manuals :)
When opening the liquid valve its refrigerant you hear flowing.., not air😇
16:42 I was wondering if it took two people! I’m sold. I’ve bought several items from SIGSolar and this is on my goto list x4 - well done! 😊
Very nice video. Is there a 36k btu or multizone version coming up soon?
We have not been notified of one yet!
Will EG4 add a multi -zone mini split in the future?
We haven't been made aware of anything like this yet! However EG4 is always coming out with new ideas and updating their products!
Can someone at Signature or EG4 explain why the line set extensions they carry don't work on the 12k AC/DC, but work on all other models?
Something should be available soon!
All I want to do is A/C and Heat an 64sqft deer stand only option is 12K??. If that is all I can get it is what it so as I want solar only lol. I truly love the service I have received at Signature Solar.
There are systems that have there own solar panel system.
Hi @rodneyross5282! Thank you so much for your feedback! Our goal is to give the best service to our customers and it's wonderful to hear we are doing just that.
I spoke with our design manager a moment ago regarding your deer stand and he had some well-prepared and cost-effective ideas due to his experience in solar and hunting and recommends giving our team a call as he believes there may be a better option than the 12k for this setup.
@@SignatureSolar Thank you. Who do I talk with? It will be interesting to see what would work better.
Please send me an email at engagement@signaturesolar.com including your contact information and any additional details about your ideas and objectives. I will then connect you with a member of our design team, who has already been briefed by their manager on the recommended system for your needs.

This is just a MR. Cool with a repackage right? Same exact mount and lines.
We are a distribution company. EG4 is a manufacturer, you would need to reach out to them for that information.
@@SignatureSolar EG4 is selling rebranded Chinese Deye units.
how long are the included lines? . In other words how far will this reach? do they sell a EG4 Mini Split Line Set for this type of setup?
The drain pipe is 1.5 meters. The connecting pipe is 5 meters. The maximum line set length depends on your system - [09k/12k = 49ft] [18k system = 66ft] [24k system = 66ft] [36k system = 98ft]
When running, If it becomes cloudy and not enough solar capacity is being generated, does the unit shut off to a point where someone needs to physically turn on from handheld remote. Or when enough solar energy generated returns does it resume cooling on its own?
As soon as it senses the solar again, it’ll come back on!
Max solar voltage is 380 watts???
Max voltage is 380v. Max wattage for the compressor is 2250w.
@@SignatureSolarcan you over watt? But not over 380v when paneling?
!!! Make very sure the cardboard template matches the indoor unit! Especially the hole. In this video you see the hoses come out of the unit a few inches from the right side, and the hole in the template matches that location. On my model the hoses are coming out directly against the right side of the unit, and stupid me had already drilled the hole in the location the (wrong) template provided, which was therefore several inches off. I had to very carefully bend the hoses inside the unit to get them to that wrong location, which was a tight bending I would rather not have done. To add insult to injury the hole cover provided was sticking out under the bottom of the unit, preventing it from locking properly into place. I replaced it with a rubber 'flanged spud washer' that I fitted around some PVC pipe that I led through the hole. Another flanged spud washer on the other side made that hole a nice looking tube with no sharp edges. This was an indoor hole from my kitchen area into my laundry room. The 15 feet of hose supplied with the unit was enough to get to the other side where I did the same thing, using a PVC pipe and washers through the outside wall right next to where the unit hangs. I have only 1 small loop in both hoses that I can easily hide indoor behind a closet that does not touch the wall anyway.
Thank you for this feedback! We will inform the manufacturer of your finding! Please let us know if there is anything we can help with!
I've got one green screw for ground on the outdoor unit. Can I use the same ground for the Ac plug and the communication cables?
We unfortunately cannot advise on the AC side of things but we do recommend reaching out to a certified electrician to address this with you. Grounding is very important for safety!
The maual that comes with it is terrible. Doesn't even tell you how to change the display from Celsius to Fahrenheit. Thank you for sharing that information in the video.
Thank you so much for the feedback!

@@jumpout4660 It took like 3 tries. You need hold down long both times.
PayMent plans?
Hi! We don't have a payment plan but you can use Affirm when purchasing on our website!
Quick question: why does the indoor head unit appear to be rather large? The size appears to be similar to a regular 18k btu unit
The Minisplit unit dimensins are: 33.1×8.1×11.6 in. - The 18kPV dimensions are 34.3×20.5×11.2 in - So it's quite close!
@@SignatureSolar Bummer, I was hoping to be able to use this 12k unit in my travel trailer, but I have only 32” for a super tight fit between some overhead cabinets. Thank you for your prompt response!
You're so welcome!
Hello what is the average installation labor time / hours on the eg4 mini splits without adding solar?
The average is a couple of hours but it depends on the installer.
How many and which solar panels for the 12000 btu mini split ac/dc?DC?

Mine came with sealant putty. What is the intended use for it?
To seal the hole you feed the line set through to the outside
question: Do electrical connections in 12000BTU 120v equipment not use a disconnect switch for the outdoor unit?thank
Not typically. You can use one but a 20A breaker will suffice :) The disconnect is typically for central AC units
how do you change the display from celsius to farnheit ? on the hybrid model
Hold the temperature up and down buttons at the same time
Does the indoor unit fan run consistently?
Yes, it slows to keep temperature but does not stop.
Can I split the solar input for the hybrid converter and hybrid HVAC?
It is not advisable to divide a single solar input in this manner because the two units will be unaware of each other's presence. As a result, they may continuously attempt to draw more power from the solar array than it can effectively generate.
do you need to vacuum the lines?
No, the line sets are pre-vacuumed.

My climate (Calif Coastal) wants a heat pump all winter, but only needs a few days of cooling in heat waves. It looks like you dedicate solar panels to the hybrid. Q1: If I have 8 solar panels in series under 380V and under 12A can I wire them to my hybrid and my in solar inverter in parallel so DC output not needed by the hybrid, can flow to the Inverter and still provide become AC power for my house? Q2: if Strategy 1 does not work in real time parallel, can it work by turning the hybrid off in the summer until it's needed. (Then summer solar would go to inverter and house as AC current until hybrid is turned on to take all the solar DC current.)
Our recommendation is to run a single dedicated PV array for the Mini-Splits. This approach ensures optimal performance and efficiency for your system.
Do I need an inverter or does it connect directly to panel.
The hybrid can connect directly to solar panels!
If I planned to use the hybrid 12000 in an off grid or grid down situation can this unit be set up to run on battery and inverter at night or no grid.
Yes it can
Will a cassette style system be available?
Not at this time
What size did you use to drill through wall? 3" or 4" hole saw?
For the 9K and 12K, 2.5 inches. But the manual states that 3.5 inch holes are needed for the 24K.
❤
Can the 24k BTU hook up to delta pros with double voltage hub?
I'm so sorry @ColbyBlack, this would be a question for Delta. If there is anything else we can help you with, please don't hesitate to reach back out to us at any time!
Let me ask this another way, if i have L1, L2, a neutral and a ground coming from a 24 kW battery and inverter at 60 hz
“AC output socket (120V/240V 30A max.) - Backup UPS Supports 120V/240V 30A max output and 20 ms UPS”
Can I take L1 and L2 from the source and connect it to the L1 and L2 in the outside unit, and the ground to ground, and cap off neutral.
Can i install this in my rv travel trailer?
The measurements that are listed in the specs to mount this from the ceiling and the floor are for typical 8 foot walls, so that would be different but otherwise, Yes!
No vacuum under 400 microns needed ?
No vacuum needed! These are pre vacuumed lines :)
Where do you get that torque wrench?
You can get the torque wrench at any hardware store :)
Is this unit 120volt?
the 9 and 12k are, the 24k is 240v

@@SignatureSolar Thank you.
How do you run it and make sure it doesn't run in a brown out condition. Is what I would like to know
If it wired to solar inverter. And you do not want to run it you have to shutdown it yourself. If it on grid it shut it self off due to no power from grid.
@@Tonyinmemphis Say I want it to run only on solar power. Now the sun goes down. Won't it burn out my motor in the pump? Has the amperage drops? You'd think there might be a low amperage shut off. You wouldn't want to stay. The point being, you don't want to stand there and wait for the Sun to start going down and then randomly shut it off. When you think the Ambridge is dropping.
@@chuckb9867 This unit same as all mini splits they run on less amps. This one there showing is a addon for a solar system with battery backup. There could have the amp draw on there site and if unit is 115v or 220v. I do not know what the fail safe is for low power. most inverter's will shut down low power. Being in a stand and open air you need check the filter weekly. Shoot me one lol .
@@anthonymartin2412 If the low Power shut off is in the inverter. I wonder how it works on the twelve volt side
2:32 I believe you meant to say 380 VOLTS not watts. Thanks for the upload.
Wow! You are correct! My mistake, thank you! Good catch!
OK. I plan on mounting it in a motorhome with a 78-inch ceiling. How can I mount it 98 1/2 inches off the ground when I only have 78 inches from floor to ceiling? Can I mount it a little closer to the ceiling, say 4 inches, since the ceiling is so low, or must it have the full 6 inches to fit?
We reccomend following the instructions in the manual ☀️
@@SignatureSolar The instructions in the manual are contradictory for my application. If I mount it 6 inches from the ceiling, as the manual suggests, I won't have 98 1/2 inches off the floor. If I subtract the 27.6" height of the head unit, I will only be able to mount it 50.4" off the floor, about half of the 98 1/2" that the manual suggests. Is this optimal for my application? If you don't know, is there someone at the factory I could speak to about the install? Thanks.
You may run into code issues if you don't follow the measurements suggested in the manual if you are in an area that requires an inspection.
@@SignatureSolar We don't seem to be communicating. The installation would be in a motorhome. There are no applicable codes for a motorhome. Are you saying that this unit can only be mounted on walls 11ft or higher? Because that is what the manual's specifications suggest if you add up the 6" from the ceiling, 27.6" of the head unit and 98.5 inches it must be mounted off the floor. I guess every house with 8 ft ceilings can't install this unit then. Please re-read my previous posts. Thanks.
@@SuperSushidog The product has requirements that don't match your situation. The units are not compatible even with 8ft ceilings.
Mount how far from the ground?
Hi @user-lz5pe9df4y The Mini Split doesn't require a specific height from the ground; rather, it should be measured from the ceiling. If you have any other questions or need guidance with install, please do not hesitate to give us a call, we are here to help!
Yeah. I heard 98" of ground and most ceilings are 96 at best.
@@SignatureSolar For whatever reason, the manual on page 7 specifies a minimum clearance between the bottom of the indoor unit and the floor as 2.5 meter which is 98.42 inches. This would require 10 foot ceilings.
I have an odd Quick connect on my unit labeled AB With a red and white wire anybody know what that’s for. It’s on it’s in my indoor unit underneath the cover near the terminals
It's an unused port.
Why not make the signal wire a plug and play like your competitors?
Great question! We will forward this to the manufacturer :)

Is it possible to run the smart cable, drain line, and copper lines inside the wall cavity and exit at the desired location at the bottom bottom?
While it's feasible, the risk of drain line leakage in the wall cavity is a concern. Additionally, the stiffness of copper lines makes it challenging to install them within the wall, posing a risk of kinking or damage.
I had no luck changing to farenheit
Try pressing the temperature up button and the fan button at the same time for 3 seconds in the shutdown state and this should allow you to switch it
Aka heat pump
