Im just after some advice on a suitable circuit breaker between the panels and the mppt
I will be installing 3 (potentially a 4th in the future) Victron poly 175w panels in series and a Smartsolar 100/50 MPPT but am unsure of which circuit breaker to install between the 2 in order to isolate the panels if need be and also for safety.
Given voltage will be up around the 72 mark what would you suggest? With 4 panels it will be around 94v
Between the MPPT and batteries would it be advisible to install a 60 or 70amp medium duty thermal circuit breaker?
