The DC circuit is no different than a fuse if it gets "popped" it can be reset.Hello, I am new here and plan to build a PV system in my van. I start with a stupid question ... What is the job of this DC-Braeker? Some people say it is cut for "backflow" ?! but I'm going to use an MPPT, how can I get a "reverse current"? And if I have a short circuit at the DC input of the MPPT or in connection with the solar cell, the current is not more than 5-6 amps. so the DC Braeker would never trigger.
many thanks for your help
It is not a diode.
If it is on the panel side then back feed from the battery to the panel is not possible.
Get a DC Circuit breaker just an amp or so higher than the IMP you expect to setup. (that is, the maximum amps you intend to have)
