I'm using a single 95AH AGM battery. Limited output, but that's what I have. The charge controller is a 20 amp older Renogy, new in box that's only for lead/acid. I also have a 40 amp Renogy, also NIB.
I'm just charging cellphone and running a few strings of COB LED lights. The panels are 100w...
Both CCs (20&40 amp) I have are MPPT, but older and don't have an option for lithium. I bought the system some years back and its just sat in the boxes, cool and dry.
This is the simple answer that's useful to beginners. I've got a 40 amp renogy rover. I'm still a bit unclear how many watts I can input at 12 volts and 24 volts.
I'm building a 200 watt system. Will's video shows the two panels in series. This will feed 24 volts into the charge controller, right? Will the controller then automatically feed 12 volts into the battery?
