I am new to 12V systems and am currently specing out / purchasing components for my 2020 4x4 sprinter conversion power system. I have purchased 2 x 12/12 30A Orion-Tr Isolated smart units since I am looking to obtain 60A charging capabilities. I am building a 12V 400Ah battery system. I see the fusing recommendations are 60A at the starter battery and 60A at the auxiliary battery side, this is however in the case of having a single 12/12 30A Isolated unit.
What would the fusing reccomendation be for two units in parallel? do I fuse / circuit breaker them separately effectively having 4 fuses configured? If not I would appreciate any documentation links or schematics I can refer to. Any input is appreciated!
So far I am using Blue Sea Systems components for Bus Bars, Battery Switches and Circuit Breakers.
