12 volt vs 24 volt charging for boat 12v system mppt
Hello, i looking for some assistance wiring my panels for a boat system. Boat will also have alternator charging and a 120 volt changer when close to shore power. But im building an off grid solar charging system for when i go camping. The biggest panels i could fit were (2) 210 watts 12 volt panels. I bought a victron mppt 150 / 35 charge controller. My battery bank is (2) 12 volt 100ah battle born batteries. This 2 battery 12 volt bank feeds alot of 12 volt accessories. My question is do i run the panels to the mppt charger in 12 volt or 24 volt? Im sure 24 volt wil be more efficient but im worried about surpassing my 35 amp max. I doubt that will happen but its a bit confusing for me and i only want to start wiring when i fully understand the system. I did calculate this at some point which lead me to buying the 150/35 victron and i believe i had good amperage to spare..... any insight?
