This is a very timely discussion for us also as we have
many Midnight MNPV6 discos in the sun. Though we're careful about
tightening wire landings, using contact cleaner for the fuses and fuse
holders, some installs seem to get hotter than others. We just started

In my experiance if the combiner is in the sun breakers will be hot
breakers are a thermal device and should be kept at room temperature. Try
substituting the HCAC type breaker for the stanard breaker

tripped again a few days ago. It was the same branch this time.

Hi Chad
Was the enphase monitoring able to locate the bad inverter? Or trial and error?

I'm trying to resolve an intermittent frustrating problem with and Enphase
IQ system. There are three AC Branch circuits of 9 microinverters each
coming into an Enphase AC combiner.
What has been happening is one of the BR220 branch circuit breakers and the
