40volts in to the charge controller. will it step it down to charge a 24 volt battery bank ?

At 40 volts DC I am unsure of. I can assure you of 30 Volts DC it will work well with. Incoming voltage (DC) is supposed to be higher for charging.

I've not heard of doing that on this controller. Don't think I would try it!

This One is supposed to decide 12 or 24 for you once hooked up. I have 6 hooked up on a 12 volt System. It should work fine the AMPs are another issue it may say 30 Amps but I doubt it I would do the math and keep it under 18. Just a FYI hook it up as soon as you get it. If its Bad send it back fast. Had to send two bad oones back. The good ones are vey stable. The manual is horrible all in all not a bad cc

I use my charge controller with a 12 volt converter, but I think you can put as much power in as you want,and that it will charge a 24 volt battery bank.Since I have 12 volt converter, I had to put all my 12 volt batteries in parallel, so as not to go above 12 volts and exceed the converters volts

If you have 4 250 watt pannels at 24 volts that is 1000 watts at 24 volts. That would be a total current into the charge controller of 41.66 amps which would be within the 45 amp limit. However on a 12 volt system it is charging the batteries at (1000 watts / 12 volts) 83.3 amps which is beyond the charger controllers specified ratings. If you went to a 24 volt system it would work otherwise you would have to have 2 of these (2 panels per charge controller)

Actually neither. It delivers maximum power at 31.64V. This panel is made for working with an appropriate grid tie inverter, but it probably would work well for charging a 24V battery bank as well.

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.

I threw the packaging away. But i believe it listed 30 volts as top input. I used it to drop down a 24 volt to 12 volt and it works good.

Dont know if i understand your question. But it doesn't sound like it would work because one 12v panel wont charge 24v battery unless you connect two 12v panels in series.

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.

Only if your bank of batteries is wired 48volts. It WILL NOT charge at any other voltage than 48volts.

not sure as it is rated for 24 volts power source. Try it, it wont hurt it.

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

Yes. I checked the number on our 40-volt batteries and it is the same. We have used it to charge both the 36 and the 40 volt.

I don't believe it is a 24 volt charger per se but depending on which charger you have it can charge one or two 12 volt batteries at a timeSo one 24 volt battery noBut if two 12 set up for 24 volt yes

I believe this has an internal voltage regulator but im not sure about 24 volt sorce

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.

No, I think the generator inside the unit is set to generate 12V. The controller that goes with this system is also 12V so unless there is a controller that can convert to 24V, then you may need to find another way to convert the charge. I 24V system is more expensive though? FYI.

Nope. It will probably regulate close to 28 volts, so you would have to arrange your batteries in a 24 volt configuration.

The solar panel voltage must be higher than the battery voltage you are charging. A 12Volt (open-circuit about 18 Volts) solar panel will not charge a 24 volt battery.
