[RE-wrenches] Module - microinverter compatibility question

[Jerry Shafer]

Wrenches
In the am it will latch up but in the hotter days the inverter may not
reconnect in the event of corrected outage resulting in no production
through the rest of the day, if the VMPPT falls below minimum tracking you
might not get much production due to fixed power settings. I have seen this
issue from other combo's.
Suggest either a different inverter or module.
