I recently bought a Victron MPPT controller and I installed it yesterday at a remote location that gets attened once a month.
I have fed it with two 300W panels in series giving me 80V@10A (Overkill I know but those are the panels available to me)
I have installed 10A circuit breakers on both the Positive and Negative before the PV feeds into the Controller. Cable for the PV is 4mm2
I have the Controller charging two identical lead acid truck batteries in series - their capacity would be 300 to 400AH combined. Setting is at 24V. Cable for the charge cable is 10mm2
Using bluetooth I set the charging algorithim to the "Default 2" setting at the advice of an off the grid electrician.
Can you guys give me advice as to how safe this setup is? I am primarily worried about the Charging Algorithim as the descriptions didn't seem to fit exactly with my battery hardware.
