I turned them off before the recent inclement weather as advised by our local council.

I meant to do it last week, but I kept forgetting.

I turned the DC and the AC back on in the reverse of the order suggested for turning them off.

I watched the panels from across the road for a bit, to watch for anything obviously amiss. (I assume sparks, smoke and fire to be the obvious problems to watch for). We didn’t and up getting hit by the terrible weather event, so I wasn’t too worried.

The panels seemed to come up ok.

    Yes, this is a requirement in order for the inverters to be certified and thus be sold. So unless someone imports something directly from China and it happens to be made very dodgy, the inverters will shut off when the mains input goes down.

    There was even a bit of an issue with micro-inverters. The regulations in the EU said the inverter should physically disconnect, but a lot of micro-inverters used solid state switches to disconnect. IIRC the language was then changed to just specify it should disconnect and not how it should do that.
