[RE-wrenches] 60 Amp PV breaker tripping

[Daniel Tittmann]

The classic 150 with a 100 amp breaker tripping.  Solution was to swap out
the charge controller and breaker.  No more problems, sent them both back
to midnite and they both tested fine.  New controller and breaker are
working fine.  Never did find what was causing the issue just found a
solution.
Cheers-
Daniel
