We have a photo-voltaic system with a battery bank configured to 24 Volts. There were sound reasons for going this way, but it has made headaches because 24 V equipment is hard to find and expensive to buy.
My question is this; when we have a few cloudy days and I need to charge the battery bank, can I just wire up two 12 V chargers in series to do the trick or is this too good to be true? Would it be likely to damage the chargers? I would be running these off the dual outputs of a gas generator.
Reason - 12 v chargers are readily available and cheap. 24 V chargers are a special order and several hundred dollars.
Thanks for any help!
