I'll say it again. Beautiful system!! Cleanest system I have seen. Good honest review!! On the flickering can you adjust frequency range by widening it a couple of points. It's usually available on inverters that have gen inputs to handle generators with dirty power or other countries that don't have reliable and subject to power fluctuations. If possible widen the range staring at 59.5 Hz to say 60.8 Hz. I have very clean power but my system is set at low 59.3 Hz to high 60.5 Hz. I set it this way to offset any potential issues with LED lighting or sudden surges such as going from idle to stove or A/C coming on. I have no flicker if I'm on or off grid no matter what appliances are on or off Transfer time for my system from grid to is 2ms. You would think that MPP would respond to custmers with the popularity of their units. They sell a ton of them. Again beautiful system.
There is no such settings on these inverters. That is where more expensive units outshine MPP Solar. But hey for 26KW at $4500 one must accept it. Thank you, How are bees doing?
@@DMIINC2013 You are right for the price you can't beat what you have and it performs. Bees are doing great so far. Really don't plan on harvesting honey until next year. One thing we noticed is crops started growing early this year. We think it is because of increased pollination earlier. Makes a difference when you have 20,000 bees in your backyard. Will be adding a couple more hives next year and going take a half acre and plant nothing but different flowers for next year.
Thanks for the nice review and overview. I'm considering these as a backup for my existing inverters, these seem like a good deal. I get similar flickering with SMA SI6048US on some LED bulbs, when the inverters are close to zero load, there is hysteresis in battery voltage between charging or discharging.
@@AGhostInTheMachine well, like he says in the video, flickering happens when the inverter is close to zero load. You could call hysteresis the difference in battery voltage If charging slightly, vs discharging slightly. It's discontinuous and the inverter is switching between discharging or charging the battery.
@@DMIINC2013 I consider the flickering a feature: it tells me that my solar production is just about equal with the loads overall. It seems to be with the least expensive led bulbs. Others that are higher light output we use in the kitchen don't seem to flicker much. My wife can notice in some lights but does not complain once I explained why and when it happens.
Great over view! I think you'll be happy with the results once your power is connected. The transfer time is I believe 20milli seconds. I can confirm in my case that this is so quick there is barely a blink! My case is a bit different than yours, but my focus is to use the batteries at night, then solar to charge batteries and run the house in the day. Will be fun fine tuning this. My guy is coming out to give me a quote next week on the solar panels, but realistically I'll be happy if they are installed by winter at this point. Thanks for the update! Dan
Nice. Can't wait to see your solar side. Maybe I did not explain in detail but I am going to use solar for as long as I can while auto switching to grid only when necessary. That will be in automation part later on.
Wish you I could get in touch with you. I would like poke your brain and ask questions in regards to finishing up install so when time comes I will pass inspection with out issues.
It's good they are UL1741. Additional considerations for a system with DC coupled arrays are rapid shutdown, arc fault and ground fault detection. I worry about arc-faults occurring, and I'm adding Sensata PVAF-T and remote trip breakers to detect and shutdown the solar array. The remote trip breakers can also be tripped by other controls to create rapid shutdown, analogous to Midnite Solar's Birdhouse rapid shutdown system.

Unstable operation of MPPT inverters at low PV voltages (but over the rated MPPT operating range!) Is characteristic of all Chinese inverters that I know. And I know a lot of different Chinese inverters (used on the European market). The REVO series has a similar feature, but they work quietly even above the allowable 500V - I saw Revo II with my own eyes working on 550 volatts from PV panels, but it also started to "stutter" at 230 volts (200 V lower limit). Apparently this is a hardware effect, not a software problem. The best remedy is to select the number of panels in the string so that the PV voltage is as close to the allowable as possible, but without exceeding this value.
MPP Solar is going to start selling a Deye/SunSync/Sol-Ark rebranded UL Listed unit. So that's going to be a good option for better UI, higher pv voltage, higher efficiency and better mppt algorithm. It's probably going to be at least double the price of one of your inverters though.
@@DMIINC2013 I don't think they have an official announcement but they are listed at their website under upcoming new products. Model is LVX6048WP for the waterproof split phase 7.5k model.
I haven't measured precisely, but the standby consumption seems generally similar to my pair of SMA SI6048US. It could be worth turning off two of the inverters overnight, if it could be automated.
I have been running the lv6548's in 2 phase with 2 inverters in each phase. I would get flickering lights here and there but it was about half and half. However, I recently added 2 more lv6548s so now I'm running 2 phase with 3 inverters in each phase. Since this update, I haven't experience any flickering lights, still testing though.
Only if you are using 2 inverters for split phase. When you are using 4 for split phase or 6 then you connect current sharing cables between inverters on each leg of the phase.
Hi, awesome video. and congrats on your system. if possible can you make a video about; how to wire the 4 inverters together and the setting (ac input into each inverter, ac output from each inverter and setting for each inverter to make them into split phase 240v (which one is P1 and P2). Im in the process of getting 4 of them. Thank you
Yes I can. However I have always chosen not to do so. One simple reason. People always find the way to blow stuff up no matter how good the instructions are and I just prefer for them not to associate me with their self created problem. On the other hand I always try to help out where I can via email which is posted on about page of the channel. What experience you have with electrical work?
I have twin lv6548’s and I see the LED lights flickering only when there’s next to no load and the Keurig coffee machine is brewing(base model from Costco). That coffee machine pulses to control heating element. The Mpp easily runs a 30 amp dryer and the old tech 2 ton AC at the same time. However if it needs to transfer to the grid because batteries or solar isn’t enough and it’s under high loads the TV may have to be restarted. If you have LED lighting you will definitely notice a flicker during transfer but AC and fridge won’t care. For the most part I don’t even think about it anymore and it just keeps things running by itself. Stops charging at 56.2 back to grid at 51. Heltec balancer set work only above 54.4 (3.4vpc). Delta typically below .005 on the flat of the curve. May rise to .020 with high loads. 32kwh bank.
I am also seeing the flickering (Off Grid Only, single unit LV6548) with one battery bank. Once I have added 3 more EG4 batteries it goes away for some reason.
Do these inverters have an automatic transfer switch to keep from backfeeding the grid when grid power is down? Thank you for your posts. I am in the process of designing my system and your video are a wealth of information.
Do you have any additional info regarding your raspberry pi set up for data logging? Been looking at current sensors for the DC/battery side of things and been having trouble
It took a UA-cam repair video to show me that my Inverter was physically broken on the inside and that's why I couldn't get it to act right someone on eBay sold me a used broken inverter so I'm going to buy me a new one instead very soon I just want to thank those who tried to help me here on UA-cam
Almost 91% efficiency? That's incredibly good for 4 inverters, I will say. AS far as the Watchpower software goes, I suspect it's intended to mostly be a way to give general statistics and the ability to configure the hardware without having to fiddle with the menu system on each unit.
Just wondering what does the flashing "6P" sign mean and the "pv1" mean on these im still waiting on more panels to get mines to properly charge and give me power i got volts but still no amps or watts coming in
I watched your video on the MPP 6548’s. I was wondering if you could send me a schematic of the wiring or a description. I am confused on how to wire, to and from, grid meter, main panel, and also sub panels.
Hello once again i have a question about these agm batteries i got in yesterday if im bringing in more watts from the panels then im using should the voltage drop in my batteries at all it dropped but seems to be going back up how can i tell if these batteries are any good ?
Is there a minimum amount of voltage u need coming in to these particular type of Inverters to function properly mines say norminal operating voltage 240vDC What does that actually mean thanks ?
we have just about the same things we dont like about these inverter series :) sorry i havent emailed you yet, life got a bit in the way. i do have to say that my wifi's do keep online, and i could use their app, however it doesnt really give you a good insight into anything. btw i am running 3 units in european 3 phase and have the 8000 maxes. i do believe these , the lv6048 and 7.2 max belong to the same series of hard and software.
Mpp Solar has a 24v 3600w PIP-3624 Max looks identical to the LV 6548 with the RGB lights etc but wont market them for us in the United States i just found out about them today
Hello again I love watching this video I have a question u said u need two in order to run the split phase are u able to run 120ac if u only have one unit or is it just 220-230 only with one unit
@@DMIINC2013 ohhh I wonder why they sell them as split phase units meaning they have both 240 and 120 can you take any two 120 inverters and create 240 or do you have to run them in parallel because most inverters boxes I see don't have the parallel connections
Well i got my new 355w 47.7v panels in today i hooked them up to my inverter thats similar to urs te 3000w version and im still getting no watts and no amps coming in im up to 230V dc from my panels and im getting noting its just sitting here draining my batteries unbelievable all this money i spent i cant even get no help on here and Ebay wont give me my money back..
All depends on what are you trying to accomplish.... 1 is not enough what I need it to do since I have split phase requirement. I do make my own power walls so no opinion on prebuilt ones.
Hi, can you give me some feedback with regards to your new setup, how does the new inverter LV6548 compair to the old LV5048? Right now we live in an appartment and here in Portugal we have a main breaker from the grid supplyer of 6.9kw, if you try to pull more it will trigger the breaker and I have to turn on the breaker again. This is happening from now and then when we are cooking (induction stoof) when we turn on the water heater:) I´am building a new house and wan´t to build a solar system that can supply all our electrical needs, it will be grid tied:)
My main concern is that at our new house we will have 2 hot water heaters installed in serie, on days with less sun only one of them will work, each one is 1.5kw. Then we will have air conditioning that will cool and heat the house, 4 bed rooms, kitchen, living room, dining room and office and the normal stuf in the kitchen, induction stoof, dishwasher, oven, micro wave and the washing machine in the loundry. Outside we will have a water pump in the well to water the garden of about 1kw and a swimming pool pump of about 1kw. The MPP Solar inverters are build by Voltronic and here in europe I can get the same models. The LV6548 is called Voltronic Max 8kw, it has the same specs at 230V but max power is 8kw. The LV5048 is called here Axpert mksIII same specs at 230V. My system setup will be 16 jinko 530w panels, 2 string of 8 in serie. Now with regards to the inverter I will have 2 options the first one is using one 8kw inverter (the same inverter you are using right now LV6548) all will be within specs but only max pv is 8480W (2x4240W) and in the manual max pv is 8000w (2x4000W). Or using 2 Axpert MKS III inverters (your old inverters LV5048) in parallel with the same panels but this time max pv for the inverter is 5000w and with 8 panels in serie per inverter this will give me 4240w well below the max allowed pv max (5000W) and I will be able to get 10kw of load instead of the 8kw of the other inverter that has 2 pv inputs. I will be using a 20kw battary bank. Now my big question is how do the inverters handle max power loads? The diferance between the big 8kw inverter or running the 2 smaller inverts of 5kw in parallel is small, about 400 euro. If I go for the 2 inverters in parallel I think that I will be able to divide the load better over the 2 inverts and I get an aditional 2kw of power and if I look at the max solar charge current on the parallel setup will be 2x80A=160A and on the big inverter it is only 120A. You have used both so can you give me a comparison of the inverts, noise at max load, can they handle max load and all that stuff. Thanks
Easy answer. Judging by all of the things you are planing to run in your new home I would go with 2 x Axpert MAX 7200-48-230. Loads will only grow over time. Another question for you. Are you going to have 3 phase outlets in your home?
@@DMIINC2013 Yes, you are probably right. The price diferance between installing 1 x Axpert MAX 8000-48-230 or 2 x Axpert MAX 7200-48-230 is only 700 euro and price diferance between 2xMKS III 5kw and 2xMAX 7200 is 400 euro. If I install 2 x Axpert MAX 7200 I will have adicional room to increase pv watts, not by much, only adicional 4 extra panels, because the flat roof can only handle max 20 panels. Have to move away from the borders and the chimney so I don´t get shade on the panels. The main benefit of this setup is that the load will be spread over the 2 inverters and the max solar charging current of the batteries will be 2 x 80A = 160A and that is about 7680W making almost total use of all the solar panels available. My only concert is the min voltage of the panels, on every PV Input I will connect 4 panels in serie this will give a min voltage at the highest temp of 136V, this is within the MPPT Operating Range of 90-450 VDC but on the low side. I don´t know if this will influence the time solar will start and end on the day. I´am going to have 1 phase.
@@khaledewida I do not think you understand. They are there and working. I sold that place and moved on. But still have the remote access to the inverters. Cheers.
May i ask what's the brand and model of the networking hub or switch ur using with the Raspberry Pi units ima be ordering me two Raspberrys for my two inverters

This only thing I understood from the video was the price. I’m in the Philippines and tried contacting MPP Solar directly, they forwarded a contact in USA. I tried again and this time I received 2 contacts one of which had no email address. The second has an address but after sending a request and details of what my electrical consumption consisted of, I got tire of waiting and sent another message to the manufacturer in Taiwan. In turn I received a reply and was told I would be given a quote for a unit. Here I am days later still waiting. Does anyone know of high quality gear as an alternative that I could readily get info and possibly buy equipment from?
you can order them and have them delivered to PH directly by mpp solar. Ask to peggy , local dealers are just too expensive. Be aware, you need the European version in PH. Ex: PIP7248 MAX or PIP8048 MAX. Be aware that if you really don't understand anything except price, you will need someone to help you or you will need to educate yourself about solar. Good luck
@@sergea1138 I’ve been in touch with Peggy many times but she actually not much help to me. Peggy keeps referring me to a Philippine dealer quite far away from me. She has never offered direct purchasing. The Philippine dealer and I have texted back and forth a few times where he has given me pricing. Like you said, the prices seem to be higher than what I’ve seen in other areas and shipping costs within the country is super high. I’m going to wait a while to do some more research before I inquired again. Thanks for your reply. God bless
The Mppt voltage range on mines is 120 volt to 240 volt so I guess I bought a broken inverter I have at least 150 volts to 180 volts coming into this Inverter but yet it won't charge my batteries or read the amp or the watts from the panels 😞

That coffee machine pulses to control heating element. The Mpp easily runs a 30 amp dryer and the old tech 2 ton AC at the same time. However if it needs to transfer to the grid because batteries or solar isn’t enough and it’s under high loads the TV may have to be restarted. If you have LED lighting you will definitely notice a flicker during transfer but AC and fridge won’t care. For the most part I don’t even think about it anymore and it just keeps things running by itself. Stops charging at 56.2 back to grid at 51. Heltec balancer set work only above 54.4 (3.4vpc). Delta typically below .005 on the flat of the curve. May rise to .020 with high loads. 32kwh bank.
I am also seeing the flickering (Off Grid Only, single unit LV6548) with one battery bank. Once I have added 3 more EG4 batteries it goes away for some reason.
Do these inverters have an automatic transfer switch to keep from backfeeding the grid when grid power is down? Thank you for your posts. I am in the process of designing my system and your video are a wealth of information.
Thank you. These inverters cannot back feed to the grid at any time. They do not have capability of selling power back to the utility company.
Do you have any additional info regarding your raspberry pi set up for data logging? Been looking at current sensors for the DC/battery side of things and been having trouble
All of it originated on this page github.com/jblance/mpp-solar
It took a UA-cam repair video to show me that my Inverter was physically broken on the inside and that's why I couldn't get it to act right someone on eBay sold me a used broken inverter so I'm going to buy me a new one instead very soon I just want to thank those who tried to help me here on UA-cam
Great video!!! Are you in the US? Could a step down transformer be used to make the 240V a 110V USA usage unit?
Each LV6548 has only 120V capability. You need 2 of them in parallel to create 240. So you do not need step down transformer. Thanks for watching.
Almost 91% efficiency? That's incredibly good for 4 inverters, I will say. AS far as the Watchpower software goes, I suspect it's intended to mostly be a way to give general statistics and the ability to configure the hardware without having to fiddle with the menu system on each unit.
True. And as I said I rather have cheaper inverters that are good then upscale software.
Just wondering what does the flashing "6P" sign mean and the "pv1" mean on these im still waiting on more panels to get mines to properly charge and give me power i got volts but still no amps or watts coming in
I watched your video on the MPP 6548’s. I was wondering if you could send me a schematic of the wiring or a description.
I am confused on how to wire, to and from, grid meter, main panel, and also sub panels.
Excellent review my friend
Thank you kindly
Hello once again i have a question about these agm batteries i got in yesterday if im bringing in more watts from the panels then im using should the voltage drop in my batteries at all it dropped but seems to be going back up how can i tell if these batteries are any good ?
Love MPP. It just works.
Sounds like issues 1 and 2 could be solved with more capacitance on the inverter input and output.
Perhaps!!
Is there a minimum amount of voltage u need coming in to these particular type of Inverters to function properly mines say norminal operating voltage 240vDC What does that actually mean thanks ?
Does the 6548 pull power from the grid if your batteries can't handle the load?
So far my system design has handled all load requirements presented to it. But yes it would switch to grid if need be.
we have just about the same things we dont like about these inverter series :)
sorry i havent emailed you yet, life got a bit in the way.
i do have to say that my wifi's do keep online, and i could use their app, however it doesnt really give you a good insight into anything.
btw i am running 3 units in european 3 phase and have the 8000 maxes.
i do believe these , the lv6048 and 7.2 max belong to the same series of hard and software.
No worries!
Mpp Solar has a 24v 3600w PIP-3624 Max looks identical to the LV 6548 with the RGB lights etc but wont market them for us in the United States i just found out about them today
Hello again I love watching this video I have a question u said u need two in order to run the split phase are u able to run 120ac if u only have one unit or is it just 220-230 only with one unit
LV6548 are 120v only. You need 2 for 240 split phase.
@@DMIINC2013 ohhh I wonder why they sell them as split phase units meaning they have both 240 and 120 can you take any two 120 inverters and create 240 or do you have to run them in parallel because most inverters boxes I see don't have the parallel connections
I have 4 units hooked up. All 4 are on the same phase? How do I fix it?
One RPi per inverter, could run the RS485 together all into one? Can a unique address be set in each inverter?
Can any settings be changed over the RS485, or is it only viewing datastream from the inverters?
Normally you can daisy chain them up and hook it too one inverter. LV6548 only searches for parameters through can or rs485
How many months will it take to get a complete return on investment?
Do not know, yet! Will figure that part later. It will take less time then normal since I am charging an EV and it was all DIY.
What did you end up doing with your LV5048's ?
There's an earlier video where he shows he boxed them up, shipped and sold them.
Sold 2. I have 1 left.
Well i got my new 355w 47.7v panels in today i hooked them up to my inverter thats similar to urs te 3000w version and im still getting no watts and no amps coming in im up to 230V dc from my panels and im getting noting its just sitting here draining my batteries unbelievable all this money i spent i cant even get no help on here and Ebay wont give me my money back..
Do you have an opinion on using 1 of these MPP, and what battery do you like with it?
All depends on what are you trying to accomplish.... 1 is not enough what I need it to do since I have split phase requirement. I do make my own power walls so no opinion on prebuilt ones.
Wouid you be kind enough to compare this with a Growatt?
What size (amperage) bus bars did you use to supply the battery banks to the 4 x LV6548? 1000A rated
Home made from copper bar. If I had to guess their amp capacity I would say close to 1000 amps.
Very nice set up 😎👍🇺🇸
Thanks 👍
In your efficiency calculations did you add the charge and discharge of your batteries?
kVA from the AC side divided by kW from DC side average.
Hi, can you give me some feedback with regards to your new setup, how does the new inverter LV6548 compair to the old LV5048?
Right now we live in an appartment and here in Portugal we have a main breaker from the grid supplyer of 6.9kw, if you try to pull more it will trigger the breaker and I have to turn on the breaker again. This is happening from now and then when we are cooking (induction stoof) when we turn on the water heater:)
I´am building a new house and wan´t to build a solar system that can supply all our electrical needs, it will be grid tied:)
My main concern is that at our new house we will have 2 hot water heaters installed in serie, on days with less sun only one of them will work, each one is 1.5kw. Then we will have air conditioning that will cool and heat the house, 4 bed rooms, kitchen, living room, dining room and office and the normal stuf in the kitchen, induction stoof, dishwasher, oven, micro wave and the washing machine in the loundry. Outside we will have a water pump in the well to water the garden of about 1kw and a swimming pool pump of about 1kw.
The MPP Solar inverters are build by Voltronic and here in europe I can get the same models. The LV6548 is called Voltronic Max 8kw, it has the same specs at 230V but max power is 8kw. The LV5048 is called here Axpert mksIII same specs at 230V.
My system setup will be 16 jinko 530w panels, 2 string of 8 in serie. Now with regards to the inverter I will have 2 options the first one is using one 8kw inverter (the same inverter you are using right now LV6548) all will be within specs but only max pv is 8480W (2x4240W) and in the manual max pv is 8000w (2x4000W). Or using 2 Axpert MKS III inverters (your old inverters LV5048) in parallel with the same panels but this time max pv for the inverter is 5000w and with 8 panels in serie per inverter this will give me 4240w well below the max allowed pv max (5000W) and I will be able to get 10kw of load instead of the 8kw of the other inverter that has 2 pv inputs.
I will be using a 20kw battary bank.
Now my big question is how do the inverters handle max power loads?
The diferance between the big 8kw inverter or running the 2 smaller inverts of 5kw in parallel is small, about 400 euro. If I go for the 2 inverters in parallel I think that I will be able to divide the load better over the 2 inverts and I get an aditional 2kw of power and if I look at the max solar charge current on the parallel setup will be 2x80A=160A and on the big inverter it is only 120A.
You have used both so can you give me a comparison of the inverts, noise at max load, can they handle max load and all that stuff.
Thanks
Easy answer. Judging by all of the things you are planing to run in your new home I would go with 2 x Axpert MAX 7200-48-230. Loads will only grow over time. Another question for you. Are you going to have 3 phase outlets in your home?
@@DMIINC2013 Yes, you are probably right. The price diferance between installing 1 x Axpert MAX 8000-48-230 or 2 x Axpert MAX 7200-48-230 is only 700 euro and price diferance between 2xMKS III 5kw and 2xMAX 7200 is 400 euro. If I install 2 x Axpert MAX 7200 I will have adicional room to increase pv watts, not by much, only adicional 4 extra panels, because the flat roof can only handle max 20 panels. Have to move away from the borders and the chimney so I don´t get shade on the panels.
The main benefit of this setup is that the load will be spread over the 2 inverters and the max solar charging current of the batteries will be 2 x 80A = 160A and that is about 7680W making almost total use of all the solar panels available.
My only concert is the min voltage of the panels, on every PV Input I will connect 4 panels in serie this will give a min voltage at the highest temp of 136V, this is within the MPPT Operating Range of 90-450 VDC but on the low side. I don´t know if this will influence the time solar will start and end on the day.
I´am going to have 1 phase.
Since those inverters are capable of 450 volt DC input on MPPT controllers I would go for 8 in series.
What's the proper name of the silver pipes u have running under ur inverter to cover ur wires where can u get them ? thanks
Electric Metal Tube Conduit and a big one is Wire Way
Will you share where you bought your inverters from? Sounds like you got a very good deal on them.
From Peggy at MPP Solar in Taiwan. DHL service to the door.
Hi, do you still have these inverters, and do you still recommend it?
I do not have them anymore but owner of the home that i sold it to say that they are still working fine. I have remote access to them too.
Thank you@@DMIINC2013 can you share what did you replace it with and why
@@khaledewida I do not think you understand. They are there and working. I sold that place and moved on. But still have the remote access to the inverters. Cheers.
Great to hear. For some reason I thought you sold the inverters not the whole house. My bad. Thanks again for the insight.
Why add grid power now. Nice review.
With an addition of electric car the system is just little bit small. W/O EV it is more than enough.
May i ask what's the brand and model of the networking hub or switch ur using with the Raspberry Pi units ima be ordering me two Raspberrys for my two inverters
Any switch will work fine. It works wireless too.
@@DMIINC2013 oh ok because some network hubs & switches have one main input and 4-5 outputs and others have just inputs with no main input can wireless routers be used as a switch or network hubs ?
very swag tata!
Have you received your firmware update wishes yet?
Oh, and where (roughly) are you located?
No firmware updates from MPP as of yet!!!! Haha, probably never. I am in Gwinnett county.
This only thing I understood from the video was the price. I’m in the Philippines and tried contacting MPP Solar directly, they forwarded a contact in USA. I tried again and this time I received 2 contacts one of which had no email address. The second has an address but after sending a request and details of what my electrical consumption consisted of, I got tire of waiting and sent another message to the manufacturer in Taiwan. In turn I received a reply and was told I would be given a quote for a unit. Here I am days later still waiting. Does anyone know of high quality gear as an alternative that I could readily get info and possibly buy equipment from?
you can order them and have them delivered to PH directly by mpp solar. Ask to peggy , local dealers are just too expensive. Be aware, you need the European version in PH. Ex: PIP7248 MAX or PIP8048 MAX. Be aware that if you really don't understand anything except price, you will need someone to help you or you will need to educate yourself about solar. Good luck
@@sergea1138 I’ve been in touch with Peggy many times but she actually not much help to me. Peggy keeps referring me to a Philippine dealer quite far away from me. She has never offered direct purchasing. The Philippine dealer and I have texted back and forth a few times where he has given me pricing. Like you said, the prices seem to be higher than what I’ve seen in other areas and shipping costs within the country is super high. I’m going to wait a while to do some more research before I inquired again. Thanks for your reply. God bless
@@nelsondog100 EBay?
@@r.b.l.5841 I guess there’s a lot of counterfeit units out there and I don’t want to take a chance in buying a fake one. No eBay for me.
@@nelsondog100 did you ever get this sorted out?
The Mppt voltage range on mines is 120 volt to 240 volt so I guess I bought a broken inverter I have at least 150 volts to 180 volts coming into this Inverter but yet it won't charge my batteries or read the amp or the watts from the panels 😞
Not necessarily. Your charge settings might not be set properly.
@@DMIINC2013 what does Nominal Operating Voltage 240VDC means everybody keeps telling me I don't have enough voltage coming into the inverter for it to work properly.
Hello sir,
I want to ask you about this product which is better Growatt Or MPP ?
I want to say they are the same since they are assembled by the same company in China.
Hello i appreciate u taking the time to show s ur system i have a question im thinking about buying a Mpp product from Taiwan since i cant find them nowhere else was just wondering how long did it take for u to receive ur units and where bouts ur located ? im in Ohio are u in the States ?
It took 3 weeks. I did wire transfer of monies. I am in GA.
@@DMIINC2013 oh ok thanks I'm actually looking at ur DIY 14.8KW Solar Array video I'm trying to understand the raspberry pi part of the system and which pi do you have I'm looking on eBay Amazon
Raspberry Pi4b.
@@DMIINC2013 the the black rectangular box that sits to the left of your raspberry pi units is that part of the raspberry pi setup what box is that ? ur setup looks Soo nice
@@DMIINC2013 I found the 4GB raspberry pi 4B I'm trying to figure out what is that black rectangular box ur that's sitting to the left I like that whole wall setup on the left of ur inverters I would like to set mines up like that.
With a system like this why would you want grid power? Very nice setup!
With out EV I am 99% off grid. With EV only 75%. Might have to expand some things.
Hello I have a similar Inverter with the same controls and functions as yours my question is my max pv input voltage is only around 155v I'm getting no amps or watts from the pv or panels is my Inverter broken or something all it does is drain my batteries with out charging at all....
With out any reference to how do you have it wired up or your settings it is impossible to help.
@@DMIINC2013 I have the solar panels wiring series to add up the volts my inverter reads the votes from the panels I have 180 volts coming in but it won't read the watt or the amps someone told me these machines require 240 volt minimum in order to charge and read the watts is that true
@@diysolaradventures7894 Again, information supplied is not sufficient to provide any kind of support or advice or suggestion.
@@DMIINC2013 wow the information that I gave you is that my Inverter is hooked up the same way as yours the standard way of wiring it up & the inverter wasn't reading no amps or watts from the solar panels it was only reading the volts I was told because I don't have enough solar panels to reach 240 volt minimum input for the inverter..thanks tho.
@@diysolaradventures7894 You said you have similar inverter. That does not help. What does the sticker on side of inverter says? It gives all sorts of information. That is the bear minimum in order to even consider giving the advice that you might need. Any pictures or videos on you youtube account explaining or showing how you wired it up? Seriously, need more information.
❤💙💜💖💗💘
I have 2 of the LV6048 if anyone wants to buy them.
interested. are they still available
Could you give a link to where you bought the inverters?
from peggy@mppsolar.com They came directly from Taiwan.
@@DMIINC2013 Did you get them from your company or did you order them online yourself? How might other people be able to buy these at the same price you did?
I got them directly from Peggy at mppsolar. Nothing special. Send her an email and see what deal you can make with her.
would is use 3 inverter
Do not understand your question...
I'm planning to use 3 inverters 6.5kw, is it a good idea ?
@@jesusgodjr9873 For split phase you can use LV6548 IN COUNTS OF 2 OR 4 OR 6.
thanks
They are useless if broken no body answers you no help don't buy it
