Brilliant Scott, you answered the exact questions I needed to know. Thank you for taking the time to put together this video. Given that the timing control for the load is not very flexible on the unit itself, I think I'll switch the load to ON permanently and use a separate timer to control the power to the load. 🙂
GREAT job SCOTT!!! You've explained this better than anyone. We really appreciate the help and the time you take out of your busy schedule to teach us. Now I'm going to go watch another one of your videos and see what else I can learn from your excellent tutorials. Be safe
The clarification you gave about the USB ports was my question answered. Glad I stayed till the very end of your very helpfull video. Thank you vey much!
Hi Scott, nice explanation on the built in output port. Since this output allows to schedule the time for either 12 VDC or 24 VDC devices, it can easily drive a relay coil at one Amp. Then the relay makes it possible to control the timing of the inverter that powers 120 VAC loads. The inverter consumes power at night unless it's turned off, unless the capacity of the battery allows to resume the charge the next morning. All that depends on how much Ah your battery is capable. As far as the USB is concerned, since it's enabled all the time, it can be used for a small LED motion sensor light whenever servicing the unit at night or to power a security camera. I got a newer version of this PWM controller from Temu for about $15, but I ordered the 24 VDC to give me 720 W max or 240W if I follow your derating. Anyways, that's plenty enough to drive all four air pumps and the two 200 GPH water pumps for my pump through a 300W PWM inverter from Temu that I paid only $25 and 2 200W used solar panels at $20 each! Great deal overall!
Ah, fair enough. I was kind of assuming the "Load" connections were for something like a big resistor or an incandescent lightbulb or something similar, so if your batteries were fully charged, but the solar cells were still cranking out watts, there was somewhere for the excess power to go. Thanks for explaining this.
@@kaydog890 I actually did a bit of research after writing that comment, and the answer is that there ISN'T any excess power to get rid of. Solar cells have a sort of resistance "Sweet spot" where they produce the most amps, and the charge controller plays with this resistance to modulate the panels output. That can go all the way up to pretty much disconnecting the panels so they produce a high "open circuit" voltage, but in that state they make next to no amps. This is why disconnected solar cells don't just build up energy until they start arcing all over the place and exploding. When disconnected they see a pretty much infinitely large resistance, so produce a miniscule amount of power.......... OK, this way of describing it isn't really 100% accurate, but it's close enough to how it works to be "True enough", and it's easier to get your head around this that to take a deep dive into the science behind how solar panels work. :D It helps to think of the solar cell like a kind of battery, but one that stores it's power about 90 million miles away in the sun. :D . When a charged normal battery isn't connected to anything it's still got POTENTIAL energy inside, but without any way for it to flow from one terminal to the other it's energy that's just sitting there....... twiddling it's thumbs and waiting for something to do. Solar panels have a similar sort of potential energy in the form of the light that's constantly hitting it, the difference is, if a solar cell can't do anything with this energy it's just wasted as a slight amount of heat. In most senses though, solar cells can just be thought of like batteries. To an extent you can run them in parallel to get a higher amperage, in series to up the voltage, or a mixture of both to try and keep the open circuit voltage and total amps produced below what your charge controller and wiring can handle.
Thank you Scott, you have helped me greatly as I have the same controller (only 20amp version). The 'Chinglish' instruction sheet is confusing, so this helped me understand the functions way better, thanks again! ...I do have one problem however, my 'charge icon' (arrow from Solar icon) is suddenly not working (I have 2 x 80W slimline solar panels on top my teardrop camper trailer), but battery not receiving charge! Will look for other tutorials to help...
So to run a 12v fridge 24hours connect the fridge to the load port and the solar will charge the battery and the charge controller will manage the charging of the battery and also running the fridge?
When people talk about a float charge for a solar charge controller, I have trouble understanding if the float charge is going to be the max charged voltage, and which would shut off the power going in? They talk about the idea of 'float charge' and bulk charge, and I'm worried if I have this at the wrong ranges for my batteries if its overcharging them. And do you want to limit the float charge for some types of batteries like lead acid and AGM battery types, and what kinds of ranges? Its also hard because on the sides of the batteries they quote cycle charges and standby charges but not float charges or bulk charges. So I'm not sure how to translate those figures to the float charge, etc?
Hi Scott - You are very informative and easy to understand. I am a beginner and want to hook up the battery, controller and inverter to the 200 w solar panel. I have a 12 volt 35 AMP hour universal battery (Thunderbolt Solar), a 1500 Watt Jupiter power inverter and just ordering a controller similar to the one you show. Do you have a video that shows the process with the sizes of voltage and wattage and all. I do not know anything, so do it for folks like me. Please. Thank you.
You said 0h is from "the second the sun rises and starts producing solar power (sunrise) the load will stay on until sunset" but the setting is called dusk to dawn? Did you get it backwards?
Never have solar connected to charge controller without a battery connected if thats what you have in mind to do. It will most likely damage the controller.
Hi scott.great videos you have done...need some help.have changed to a lithium phosphate iron lifepo4 battery...on my new solar controller it has b1 b2 b3.settings...i know it's not b1..but can't work out if it's b2 or. b3...any help would be appreciated..😊
Thank you, very clear explanation. I have a couple of questions if you are able to answer, much appreciated. i have a 120W water pump, can it be run via the load setting or would i have to run it from the battery. If i run trough the load it would enable me to use an irrigation controller and a small relay to control the circuit.
Hi I have question in regards this mppt controller I have installed a water pump on my caravan but when I turn one the pump the mppt will stop working and also the display .the amp for the water pump is 15 when it start and then 7.5 amp when it running. Thanknyou
Much appreciated Scott. I have this 30amp unit. Connected to my 110 amp leisure batterles with 1 2x100w solar panel with a 1000w invertor does this sound OK.can I add another solar panel to the set up
I have this same controller, it always gets hot and smells when the sun is high and display E12 or E16. I have 6 panels on two 12v batteries. What could be the issue.
Wow I thought it had a min batt voltage you can set to cut load to prevent battery drain. The internal timer is great will set that one.= for small 12v heater after sunset in greenhouse.
A 12v relay can be connected to the load. An inverter is connected to the relay so that the relay turns inverter on. Then, larger consumers and higher voltages than 12v can be used.
Hello Scott I have a ❓🙋🏻♂️. First of all, I’m super new to the whole solar stuff but I wanted to know if u would recommend this ?: (12V 18AH Battery Rechargeable Lead Acid AGM Battery with Nut and Bolt Terminal) For a 30 watt solar kit I just purchased. My thoughts led to this battery because I read the higher AH (18AH) the faster the charge from 30 watt solar to this battery. I hope I made sense 😂
Hello.. I did buy this unit and id do not charge the battery at al. I hear about the cable must be G10 so what is wrong. I did change the cable to the battery to G10 and still not work. Must al the cables be thicker G10 cables ? I se that you do have a thicker cable that comes from the solar penal. How can i get a thinker cable to connect the solar penal to the controller ? Who can help me out of this so i can use it as soon as possible ?
I ordered a two panel solar kit. And the solar panels already have a place for wires on the back of them. As they were part of the $50 kit. At your convenience if you could help me with this I would truly appreciate it. What I'm not understanding is how I'm going to hook it up the panels when they only have an extension for the little wires? Just wanting to know if it's too late for me to do anything about it. Thank you and God Bless you!
Great explanation, however. I am trying to power 40 12v led outdoor pathway lights so I need to add a relay which is an automotive 12v 40 amp to Handel the load. I need help to figure out how to add it into the circuit.
This is the kind of video i needed but only answered half my question. Where do you find things to run the load on? For indtance lights and small fans that have the red/ blk wire to connect in. Or do we have to cut/strip wires and manually do it? Ive trued searching amazon for dc load lights but havent really come across much besides like small van lights/ for music stuff.
I'm going to use this to power a small LED light in my shed. Something like .3 amps. I put a switch by the door so I don't have to fumble in the dark to find the load on/off button on the controller. I'm hoping to use to load connection to prevent me from killing the battery if I forget to turn the light off. (My unit is a bit newer, will have to see if the discharge stop is still set to 11.3 as you explained in another video) but will that work? If the switch is "off" at the door, and the load is set for 24, will having no load on the load (because of the switch being off) cause any issues? And if I DID leave it on, would the light just keep cycling at the discharge reconnect/discharge stop? I'm thinking it would.
thats for the vid , since I am new to this I have a simple question I have a DC pump 12V 180W 80 ampere controller , can i just put the pump into the load terminal ? or shall i connect it to the battery directly ? So far i understood is the load terminal the regulated output from the Battery ? is that so far correct ?
Great video, thanks. One further question on the load on/off. If i set for 3hrs (after dusk) and use the manual on to turn on the load when it's "off" when will it turn off automatically or will it stay on indefinitely?
Your videos are to the point and that is why I decided to ask for your input. I am setting up a Solar Pond aeration with 2 100 watt panels same Controller, 100 aH 12v battery , a 225W(400W surge) inverter and a HiBlo Air pump1.6amp 120v. I need to know how to correctly connect the inverter. Should it be connected to the controller or directly to the battery leaving the load port empty. Also should all Positive 10awg wires be Fused?
Thanks for the feedback. It depends on the rated output watts your controller load can handle. In the video, mine can only handle up to 120 watts, which wouldn’t work for your setup. So I would hook directly up to the battery. And when it comes to fuses, I’m not an expert, but I would say when in doubt, it never hurts to use one. I hope that helps!
Ok , so i took a "cigarette plug adapter" and wired it into the load , so my load in now powering a cigarette socket , into the cigarette socket i plugged in a 75 watt power inverter which is so small that it doesnt have a cooling fan , and therefore doesnt waste much juice when its on. And it also has 1 USB socket and into that i plugged a USB powered light bulb , so when you turn on the load it also turns on its own work lights , so u can see the top of the battery and front of the charge controller and everything else one might want to check on at night. Thank you for explaining to me that i only had 120 watts to play with there ,,,,,, that could have gone badly otherwise lol . The 75 watt power inverter is also just enough to run my modem all night if i wanted to get my laptop running to find out why my power went out.
Thanks for the vid ! i think i have the same controller, used it over the weekend and i don't think it was working. how can i tell if the solar panel is charging my battery?
I have a question about the load side of the power manager. I have lithium batteries in my bank coming from the controller and don’t want to “mix” with my starter battery. Can I use the load side of the power manager to trickle my starter battery without harm? Thanks!
How do you set up the bulk charging parameters?....and in the beginning what are you multiplying the charger controller amps by to get the 120W of power?
I have a technical question: I am using this system for a water pump which I am as for now starting manually every day for about 30min at about mid-day. I would like to make this automatical but the options here do not seem to match with my request. The best ide that I came with is to set the discharge reconnect to it's max value and the work mode to stop at about mid-day. I didn't try this yet as I think that it would anyway work more than the 30 min what I need... The real question is : how can I set it to work only from 11h30 to 12h00 ? Maybe an external device ? Sorry for long text, I am an absolute beginner at electricity and still quite unsure of what I am doing...
Cool vid thanks, I'm trying to work out the simple math so i know what wattage the controller is effectively producing... When I switched the controlled on obviously all i could see is voltage.. So I'm i'm running 100w solar into a 12v battery can you please tell me the magic math so I know what its putting out in watts at any one time. Thanks!
I got an atempower controller that looks the same as yours. I can't get the 0H function to work to power a pond pump during the day only. When the bulb icon is on the pump works but it doesn't switch off at sunset? It just keeps going into the night and I have to switch it off manually. Any thoughts what I may have missed?
Great Video! So, could I hardwire my Jackery to the load output using the provided 12volt car adapter that came with the jackery? That way I could charge the jackery during the day and have it stop charging at sunset. Since I can already charge the jackery using the 12volt car adapter by plugging it into the cigarette lighter, seems I should be able to just chop off the 12volt adapter part and use those wires to connect to the charge controller output. Other end of the adapter already has the 8mm plug on it. Am I wrong???
Yes, that sounds like it would work. If you're wanting to tie into your existing system, then yeah, just hook up the Jackery to the load output and the Jackery should also manage charging on it's own.
Can I use the load output without connecting a battery? We are using the controller in a solar powered boat competition. Two of the races use only solar panels to power the boat. The third race, an endurance race, uses small batteries to power the motor.
Sorry Scott I made a mistake. I have 1x100w solar panel going to 2x110amp leisure batteries with 1000w inverter. Is this OK. Can I add another 100w panel to the set up.
Hi Scott, can you explain the functions marked on the manual as 2, 3 and 4 after the main display and before the timer function: 1) Floating charge: 13.7V (default, adjustable), 12.0-15.0V? : Can you explain what this is? 2) Discharge stop voltage: 10.7V (default, adjustable), 8.0-11.5V : This I managed, it's a limit set that when the battery voltage is below the set value ex. 10.7V, the controller cuts off the supply to the load. Unfortunately I couldn't set this below 8V, I guess it's to protect the battery from draining too much. 3) Discharge reconnection voltage: 12.5V (default, adjustable), 11.0-13.0V : Can you explain this function please? Thanks
In my video description I wrote this: UPDATE: If you set the timer to 0H, It actually runs from dusk to dawn, not dawn to dusk like I said in the video. Maybe that will do the trick!
Great job deciphering the code. But how on earth does the manufacturer expect the helpless user could break the secrets behind this Enigma of 1-23H, 0H 😅 Thank a lot
I'm running a 60 watt greenhouse heater through a 300 watt inverter overnight. It drains my 105 ah deep cycle battery to 10v after 2 nights? Should I be able to run this heater this way without draining the battery?
OK, so what do you actually connect to the output load, practically? I'm using with an RV...I don't have anything that would plug two wires into a controller, so still no idea what you use for that output load...?
Thank you for the information. You didn't mention if the controller remembers your settings once it is disconnected from the battery, or do you have to set up every time ??😢
so is it ok to charge your batteries with a generator when the sun hasn't shown for a couple days. do you have to disconnect from charge controller to do this
Hi Scott I have fitted a 300ah lithium battery into my caravan and had to update my MPT controller to a Mppt controller. I have a positive only load wire from the MPT. The new Victron mppt 100/50 doesn’t have a load terminal. My question is can I join my positive load and positive BATT wire together and connect to to BATT terminal on Mppt controller. I can’t get back to the battery to give the load wire power. Thanku for any feedback.
I would say the best solution would be to hook the load right off the battery terminals. But if you can’t access the battery, that makes it hard. I’m not a professional and I’m not recommending anything, but, it would make sense to me that whether the load is connected on the battery terminal or at the end of the wire hooked into the controller, that there wouldn’t be a difference. But, again, that’s my unprofessional opinion and I don’t advise it, be careful with the wiring. You just wouldn’t want an electrical fire and ability to prevent them too. I hope that helps!
Sort of, it slows the charge down to a trickle charge, which is good for batteries. It regulates how much charge the battery needs based on what you set.
i bought the same controller---- I heard you could run the panel direct to the controller and use the USB ports, but from what you said you cannot, you need a battery
My controller doesn't display "0H"but does display "00". Unfortunately, when it is set to "00" I can't get the output to turn on. I am trying to power a small 12V, 6W fountain pump during the daytime only.
I had the same issue. The controller that I am using whilst looks identical to Scott's must be different. When set to o it turns off the load while it is receiving charge from the solar panel. Even the manual states "00h - By default the DC output is turned off when there is sunlight". I just run in 24H mode and turn off the output manually when I need.
I do not take my power or load from the load buttons. I run an inverter connected directly to two 12volt batteries. This means that I can power 240 volt items like electric drills/TV/Microwave.. The inverter stops my using it when the battery goes below a critical voltage. Scott please notify me if you comment.
Yes, that's how I use it to get 110 volt power, an inverter directly off the battery because for most applications the load output doesn't provide sufficient power.
Brilliant Scott, you answered the exact questions I needed to know. Thank you for taking the time to put together this video.
Given that the timing control for the load is not very flexible on the unit itself, I think I'll switch the load to ON permanently and use a separate timer to control the power to the load. 🙂
GREAT job SCOTT!!!

Best video on this controller, I know because I saw the others.
I can run a 10" TV, Alpocool 9It fridge and a few LED lights, good vid
Nice!
Thank you, Scott! Great video and information! Concise and straightforward!
Thanks for helping us knuckle heads
what a wonderful precise and informative video, top class Scott since I could not make sense from the insturciotn with the controller
Very informative. I learned something today.
Thank you for taking the time to tell me how to set the load settings. I also email your link to myself for quick review. Nice.
You're amazing! Thank you so much for the help 😀 Mandi

Excellent Video, Very Helpful Thank You.🇬🇧
awesome! thanks for the info
Great video man, going to check my settings out to see why my battery practically dies every night and can’t get it fully charged
Haha, awesome, glad it helped!
I have the same issue kindly assist.when my battery dies after four hours I'm in darkness
Many thanks for clear explanation.
Great video. Can you connect an inverter to the load ports or directly to the battery?
Does the load take power from the battery or directly from the panel?
The battery lol
If you Load side 12v on the charger controller
Never have solar connected to charge controller without a battery connected if thats what you have in mind to do. It will most likely damage the controller.
How do i know when my lead acid battery is fully charged 😔
Hi scott.great videos you have done...need some help.have changed to a lithium phosphate iron lifepo4 battery...on my new solar controller it has b1 b2 b3.settings...i know it's not b1..but can't work out if it's b2 or. b3...any help would be appreciated..😊
Brilliantly presented video 👍
what else goes into the load??? besides a battery monitor?
Thank you, very clear explanation. I have a couple of questions if you are able to answer, much appreciated. i have a 120W water pump, can it be run via the load setting or would i have to run it from the battery. If i run trough the load it would enable me to use an irrigation controller and a small relay to control the circuit.
Is there a good way to utilize this in an RV? Everything is already either powered by shore power or inverter (when turned on).

How constant is the voltage output on the output side of the 60amp solar controller?
Hi. Can you explain the different types of batery setting? And what one is best for a conventional led acid wet battery.
Thanks.
Hi Scott, can this 30A charge controller support a 12V/30Ah battery? What type of battery do you have?
So using the usb port to charge a phone it would never go higher voltage than is draw from phone to charge?
Thanks!
Good video.
Good info.
I'm going to use this to power a small LED light in my shed. Something like .3 amps. I put a switch by the door so I don't have to fumble in the dark to find the load on/off button on the controller. I'm hoping to use to load connection to prevent me from killing the battery if I forget to turn the light off. (My unit is a bit newer, will have to see if the discharge stop is still set to 11.3 as you explained in another video) but will that work? If the switch is "off" at the door, and the load is set for 24, will having no load on the load (because of the switch being off) cause any issues? And if I DID leave it on, would the light just keep cycling at the discharge reconnect/discharge stop? I'm thinking it would.
thats for the vid , since I am new to this I have a simple question
I have a DC pump 12V 180W 80 ampere controller , can i just put the pump into the load terminal ? or shall i connect it to the battery directly ?
So far i understood is the load terminal the regulated output from the Battery ? is that so far correct ?
On the load side can you connect AC or DC appliance or bought
Can I connect a socket to the load port and power my dc devices
Great video, thanks. One further question on the load on/off. If i set for 3hrs (after dusk) and use the manual on to turn on the load when it's "off" when will it turn off automatically or will it stay on indefinitely?
Your videos are to the point and that is why I decided to ask for your input.
I am setting up a Solar Pond aeration with 2 100 watt panels same Controller, 100 aH 12v battery , a 225W(400W surge) inverter and a HiBlo Air pump1.6amp 120v. I need to know how to correctly connect the inverter. Should it be connected to the controller or directly to the battery leaving the load port empty. Also should all Positive 10awg wires be Fused?
Thanks for the feedback. It depends on the rated output watts your controller load can handle. In the video, mine can only handle up to 120 watts, which wouldn’t work for your setup. So I would hook directly up to the battery. And when it comes to fuses, I’m not an expert, but I would say when in doubt, it never hurts to use one. I hope that helps!
Ok , so i took a "cigarette plug adapter" and wired it into the load , so my load in now powering a cigarette socket , into the cigarette socket i plugged in a 75 watt power inverter which is so small that it doesnt have a cooling fan , and therefore doesnt waste much juice when its on.
And it also has 1 USB socket and into that i plugged a USB powered light bulb , so when you turn on the load it also turns on its own work lights , so u can see the top of the battery and front of the charge controller and everything else one might want to check on at night.
Thank you for explaining to me that i only had 120 watts to play with there ,,,,,, that could have gone badly otherwise lol .
The 75 watt power inverter is also just enough to run my modem all night if i wanted to get my laptop running to find out why my power went out.
Thanks for the vid ! i think i have the same controller, used it over the weekend and i don't think it was working. how can i tell if the solar panel is charging my battery?
Great video.
I have a question about the load side of the power manager. I have lithium batteries in my bank coming from the controller and don’t want to “mix” with my starter battery. Can I use the load side of the power manager to trickle my starter battery without harm?
Thanks!
How do you set up the bulk charging parameters?....and in the beginning what are you multiplying the charger controller amps by to get the 120W of power?
I have a technical question:
I am using this system for a water pump which I am as for now starting manually every day for about 30min at about mid-day.
I would like to make this automatical but the options here do not seem to match with my request.
The best ide that I came with is to set the discharge reconnect to it's max value and the work mode to stop at about mid-day. I didn't try this yet as I think that it would anyway work more than the 30 min what I need...
The real question is : how can I set it to work only from 11h30 to 12h00 ? Maybe an external device ?
Sorry for long text, I am an absolute beginner at electricity and still quite unsure of what I am doing...
Cool vid thanks, I'm trying to work out the simple math so i know what wattage the controller is effectively producing... When I switched the controlled on obviously all i could see is voltage.. So I'm i'm running 100w solar into a 12v battery can you please tell me the magic math so I know what its putting out in watts at any one time. Thanks!
I got an atempower controller that looks the same as yours. I can't get the 0H function to work to power a pond pump during the day only. When the bulb icon is on the pump works but it doesn't switch off at sunset? It just keeps going into the night and I have to switch it off manually. Any thoughts what I may have missed?
Great Video! So, could I hardwire my Jackery to the load output using the provided 12volt car adapter that came with the jackery? That way I could charge the jackery during the day and have it stop charging at sunset. Since I can already charge the jackery using the 12volt car adapter by plugging it into the cigarette lighter, seems I should be able to just chop off the 12volt adapter part and use those wires to connect to the charge controller output. Other end of the adapter already has the 8mm plug on it. Am I wrong???
Yes, that sounds like it would work. If you're wanting to tie into your existing system, then yeah, just hook up the Jackery to the load output and the Jackery should also manage charging on it's own.
BRILLANT 👌🏼👍
so i have 21 hours selected, after sunset, it will say ON for 21h, regardless if it reaches sunrise. is this correct?
Do you know if it possible to charge AGM batteries, with this controller? 😀
Hi, i just curious 1 thing, how do u set the controller 12volt for the 18 volt solar panel, i'm really wanna know about that...
Can i use 7Ah/12v battery if I want to light up chistmas lights on outside conditions?
Can I use the load output without connecting a battery? We are using the controller in a solar powered boat competition. Two of the races use only solar panels to power the boat. The third race, an endurance race, uses small batteries to power the motor.
Sorry Scott I made a mistake. I have 1x100w solar panel going to 2x110amp leisure batteries with 1000w inverter. Is this OK. Can I add another 100w panel
to the set up.
Thank you!
I think I commented another of your videos but, would you know where I can find an adapter to connect a dv(18v) to the solar controller?
Hi Scott, can you explain the functions marked on the manual as 2, 3 and 4 after the main display and before the timer function:
1) Floating charge: 13.7V (default, adjustable), 12.0-15.0V? : Can you explain what this is?
2) Discharge stop voltage: 10.7V (default, adjustable), 8.0-11.5V : This I managed, it's a limit set that when the battery voltage is below the set value ex. 10.7V, the controller cuts off the supply to the load. Unfortunately I couldn't set this below 8V, I guess it's to protect the battery from draining too much.
3) Discharge reconnection voltage: 12.5V (default, adjustable), 11.0-13.0V : Can you explain this function please?
Thanks
Good job explaing. For some reason I can't get the OH settings to work and idea
In my video description I wrote this: UPDATE: If you set the timer to 0H, It actually runs from dusk to dawn, not dawn to dusk like I said in the video. Maybe that will do the trick!
OK thank you
Great job deciphering the code. But how on earth does the manufacturer expect the helpless user could break the secrets behind this Enigma of 1-23H, 0H 😅 Thank a lot
I'm running a 60 watt greenhouse heater through a 300 watt inverter overnight. It drains my 105 ah deep cycle battery to 10v after 2 nights? Should I be able to run this heater this way without draining the battery?
Scott, when I hook the wires from the controller to the battery, it sparks, like really sparks. Why?
OK, so what do you actually connect to the output load, practically? I'm using with an RV...I don't have anything that would plug two wires into a controller, so still no idea what you use for that output load...?
Thanks Bro!!!
Thank you for the information.
You didn't mention if the controller remembers your settings once it is disconnected from the battery, or do you have to set up every time ??😢
so is it ok to charge your batteries with a generator when the sun hasn't shown for a couple days. do you have to disconnect from charge controller to do this
Hi Scott I have fitted a 300ah lithium battery into my caravan and had to update my MPT controller to a Mppt controller. I have a positive only load wire from the MPT. The new Victron mppt 100/50 doesn’t have a load terminal. My question is can I join my positive load and positive BATT wire together and connect to to BATT terminal on Mppt controller. I can’t get back to the battery to give the load wire power. Thanku for any feedback.
I would say the best solution would be to hook the load right off the battery terminals. But if you can’t access the battery, that makes it hard. I’m not a professional and I’m not recommending anything, but, it would make sense to me that whether the load is connected on the battery terminal or at the end of the wire hooked into the controller, that there wouldn’t be a difference. But, again, that’s my unprofessional opinion and I don’t advise it, be careful with the wiring. You just wouldn’t want an electrical fire and ability to prevent them too. I hope that helps!
Will it work for my electric bike

Hello, Thank you for this informative video.
Does the controller stop charging the battery automatically when it is full ?
Thank you
Sort of, it slows the charge down to a trickle charge, which is good for batteries. It regulates how much charge the battery needs based on what you set.
Does the charge module show how much you are currently drawing when the load is on?
i bought the same controller---- I heard you could run the panel direct to the controller and use the USB ports, but from what you said you cannot, you need a battery
Yes you deff need a battery connected BEFORE you connect a solar panel.
My controller doesn't display "0H"but does display "00". Unfortunately, when it is set to "00" I can't get the output to turn on. I am trying to power a small 12V, 6W fountain pump during the daytime only.
I had the same issue. The controller that I am using whilst looks identical to Scott's must be different. When set to o it turns off the load while it is receiving charge from the solar panel. Even the manual states "00h - By default the DC output is turned off when there is sunlight". I just run in 24H mode and turn off the output manually when I need.
Can I load 6 volt led bulb
I do not take my power or load from the load buttons.
I run an inverter connected directly to two 12volt batteries. This means that I can power 240 volt items like electric drills/TV/Microwave..
The inverter stops my using it when the battery goes below a critical voltage. Scott please notify me if you comment.
Yes, that's how I use it to get 110 volt power, an inverter directly off the battery because for most applications the load output doesn't provide sufficient power.
