Re: Strange electrical/Breaker issue (solar related??)

For solar you're under designed. 50% discharged batteries = 12.1V. 500W/12.1V = 41A with a 30A CC. Possibly you exceeded 40A the fuse or it was defective but actually solar output is ???. 500W is the spec for ideal light and 25C.

What does your CC do when there is more than 30A output potential considering the input? Mine derates to it's 60A spec.
