I have three 300 watt / 44 volt panels that I would like to install on pre existing 12 volt system. I've been trying to figure out what size of charge controller that's required.
I have found a few online calculators but everyone makes me doubt the other. Hooking them up in series makes sense to me to keep the voltage down but I may be wrong. Would a 150/60 charge controller work the best?
Any suggestions would be great. Thanks.
