[RE-wrenches] SolarEdge -A ON/OFF switch issue?

[Dave Tedeyan]

I figured I would report back. I went out to the site, and it turns out
that the on/off switch relay was in fact futzing out. Sometimes it would be
working just fine, but it would often get stuck in the OFF position even if
no one touches the switch. I was able to temporarily bypass it by jumping
the two pins together on the comm board where the ON/OFF wires connect.
This invalidates that on/off switch, but at least the inverter works.

Cheers,
Dave
