I am currently running 5 100W solar panels in parallel through my Victron 100|50 MPPT controller, connect to 3 12v, 125Ah AGM batteries connected in parallel.
My batteries are rated for 30A max charging current.
I am about to upgrade the solar to produce more power to recharge faster (not quite generating enough to keep up with usage). I will add two 250W panels, connected in series, to a separate controller.
My question: I don't want to overcharge the batteries. They are rated for 30A max charge current, which is currently around what my Victron controller is sending them with the current setup. If I switch my 5 100W panels to a series connection (dropping the Amps, but increasing the voltage), would that change how much current the Victron is sending to my batteries so I have room to add another controller? Or is the Victron converting the power regardless of how I have the panels configured?
