What is the maximum amount of batteries this kit will charge efficiently. Do you recommend a 12V or 24V bank, is it better to use 6V batteries or 12V?

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. rgds Emmanuel

I have 14 115ah deep cycle batteries powering a small off grid house. On a sunny day the solar system will fully charge the batteries. I will soon be adding a 400 watt wind turbine to help on cloudy days.

Glad to help! A good way to view the 400 Amp battery bank is simply as a fuel supply. At 400 Amps you should be receiving about 25 Amps back into your system per hour. To use this as a measuring stick, you would then want to be using devices that would be consuming less than 25 Amps per hour. If your devices would be consuming more than 25 Amps per hour, you would want a battery bank with more capacity. Regards, Steve, for Explore Electric

You can charge your battery. You will need to get a charge controller to convert 24V to 12V. The controller will also prevent overcharging of the battery. Get a controller rated for 10 amps or more. I don't know how long it will take to charge one battery. This is a powerful panel, and would likely charge in one day or less.

If you are out west, 400 AH @12 volts would be a good match. On the East coast, or in some place cloudy like the Pacific Northwest, you might want 600AH @ 12V. Since you want to use 6 Volt batteries, Trojan T-105 would be a good choice. Either 4 of these or six of these hooked up in pairs with a MPPT controller. However if you are asking this question, you might not be smart enough to wire these properly. Get an expert to help.

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

Hello,If you are charging 12v nominal battery bank you can input up to 400 watts of solar power.If you are charging 24v nominal battery bank you can input up to 800 watts of solar power.The wiring configuration of the 800 watt panel setup must be done so that you do not parallel all of them or not series all of them or else the panels will either go out of the 100 VDC or the 40A rating.The 800 watt setup must be wiring in series/parallel.Please let us now if you have any further questions.Regards,AW

It should be able to charge them in series as a 12 volt bank without issue as long as it can handle 2, 10 or 20 amps. You can also charge them individually as 6 volt units if you are unsure of their capacity .

I used 2, 12 volt solar panels about 150.00 each and it works good on 24 volt. I was pumping only 60 foot though and 12 volt was too slow. Buy the 12 volt solar panel with the controller it sets it at 24 volts, 2 12 volt batteries and that worked ok. I also ran a 12 volt electric fence charger off of one of the batteries.

I have charged 3 12 volt batteries hooked up in series with this. It works fine. It is best if you make sure that the charge is balanced across the 3 batteries to start with.

You will need about 300Ah worth of batteries with a 400w system asuming 50% Depth of Discharge. So if this is for a 12v system you can use 2 x 6v, 300Ah batteries in series.

Yes20v max and 12v max are the only batterys that work in that ratio.18v dont work in that ratio.But the reception aint good.

I went with 12v battery with solar charger. I made my own out of ammo can instead of buying one. Battery stays full and don't have to keep buying batteries. I used a old charger cord off regular 12v recharger. To hook to unit. Works like a champ. Only way to go in my opinion.

Yes you can use a converter 12 v.I have a bank of batteries and a converter 12 v., 1200 wat and works perfectly. Consumes about 300 wat

I would not use a 6v charger on a 12 volt battery (assuming you have a 12v battery, or why else would you ask?). The 6v battery tender charger will not even cycle on unless the battery voltage drops below a certain point, well below what you would need in your car.

This would work, but 1 12v deep cycle marine battery will not last very long. I use this with a bank of 4 marine batteries at 220ah each in my bus and it is good enough for about 12 hours using lights, TV, Radio, and mini fridge. Most people use 6v golf cart batteries. You can wire 2 together in series to make 12v, and then you can wire sets of 2 in parralell to increase amp hours (how long they last. The other thing to consider is a means of charging the battery when not in use. If you are using a single battery, a 6 amp "smart" multi-stage charger should be fine. I use a 45amp-maxx 4 stage smart charger from Go Power. Works great! This would work, but 1 12v deep cycle marine battery will not last very long.

Should work.But i suggest to find 24v DC - AC inverter and hook it directly to your batteries. Converting from 24V to 12V and then to AC voltage is not efficient at all.

Sure, you can use more than one 12v battery, but the multiple batteries must be wired in parallel, NOT series. "Parallel" means like terminals (+/-) must be wired together. You should consult an electrician if you aren't sure how to do this. I'm not sure about charging capacity - I suspect it will take longer to re-charge multiple batteries. You may want to ask Tripp Lite about that.
