Hi guys, I've invested in a 400w solar panel and a victron mppt smart controller. Just a quick question for the electrical wizards, it came with 2 125v dc breakers, a c25 one and a c63 one, I take it the breaker goes in between the mppt and the battery bank but which one do I use? I have 960ah battery bank. Do I need to connect the mppt directly to the batteries or is it ok connecting it after the battery isolator, would it damage something if the battery isolator was in the off position??
