Can I use this to make my 12v OR 24v solar panel charge my 36v battery bank?

The quick and easy answer is, Yes, it should work for that, the only thing I haven't tested with it is how it will react to loss of source voltage. You'll just have to be sure to set up the output voltage limit to the proper value for the 36 volt battery (41.4V or so for lead acid). I would also set the current limit to a value that would not overload the solar cells in normal lighting conditions.

Hello Bart. I will recommend 24v battery bank. For simplicity of wiring, I will also recommend 12v batteries. The 4 solar panels can efficiently charge 4 120AH batteries or 2 200AH batteries. Feel free to ask more questions.rgdsEmmanuel

Yes, I bought it originally because of my battery bank is also 24 Volt. This is ok. But I cant actually recommend this device. I bought it not only for inverter-function but also for charging and bypassing when generator comes into game. The last two, charging and bypassing, did never work out. I don't know if I got it already defect by bad luck or if it is just low quality.

Yes. You connect the battery with the charge controller. This is only for 12Volt battery. If you have 24volts, you will need to replace the charge controller with a MPPT one.

If you go to 1000 watt you can charge a 12v battery bank then 2000 watt for 24v battery bank with this charge controller

The answer to the second question (780 watts @ 24 volts into a 12 volt battery bank) is yes. That's what I do (600 watts 24 volt into a 12 volt battery bank.)

yes that is correct. If you connect two 12v batteries in series end result will be one battery bank of 24v. When charging batteries - use of a charge controller is highly recommended.

Not sure I use if for a solar power pack. Measure voltage of battery and the draw from the battery

I believe in a crude way it will work because the battery should clamp automatically the voltage down. However, this can only be a temporary solution. The charge controller is indeed the way to go. Try midnight solar

I used mine on a 4 unit - 6 volt battery bank in my RV. If they make a unit for 12 volt batteries I don't know. Contact the manufacturer

You are more likely to over charge the battery with a 12 volt unit. Just ensure the whole solar array is in the sunlight for optimal charging.

The short answer is that while these panels operate at around ~28 volts, they will have no problems powering a 12V system with the right charge controller. The days of matching your panels nominal voltage to your battery bank were obsoleted by MPPT charge controllers. To use an oversimplified summary- an MPPT controller takes whatever voltage and amps coming in from your panels and converts it to whatever voltage and amps your battery bank needs. (Worth noting "however," the closer your battery bank nominal voltage is to your panels the more efficient it will be). The significant price difference you will see on MPPT controllers is due to efficiency differences in this conversion, intelligence on charging the batteries, reliability, etc. MPPT controllers are very affordable and significantly increase efficiency to the point that outside of unique circumstances it's bordering on irrational to consider older PWC technology charge controllers that require you to match the panel voltage to your battery bank's nominal voltage (i.e., 12V panels to 12V batteries). A better question for you to ask and research yourself is "what is the best charge controller for these panels powering a 12V battery bank." Hopefully this helps. Good luck!

For 36V, the charger will only supply 12.5A. I believe it's the same for 48V.

No this wont work effectively. You should size the voltage on your battery bank to the voltage of your inverter. Ie; 24v battery bank and a 24v inverter. This component is only used to step the voltage down from 24v to 12v for a load. Ie; 24v battery bank and inverter with the transformer stepping down the voltage to power 12v lights (or any other12v load).

for these panels since they are 24v panels you would need an MPPT charge controller. You would also need an adapter kit to connect your panels to your charge controller an a tray cable to connect the controller to your battery bank. And since these are 24v panels you would need a 24v battery bank.

Would I be able to use this with a 280 watt panel to charge a 12 volt battery bank of 4 GC-2 6 volt batteries? Need to keep bank at 12volts to run bilge pumps: Grape Solar GS-P-280-Fab1 280-Watt Polycrystalline Solar Panel (Discontinued by Manufacturer)
