From the house to the solar panels there are these shutoff, in this order
1) AC main panel, has 2 breakers for solar feeding to grid
2) AC disconnect blade switch
3) inverter has a flip switch (inverter on/off) and also a very big DC safety disconnect switch
4) DC disconnect blade switch
5) the panels (no switch here)
It's been 4 years and I think back then, I flipped the AC blade switch first off, then the DC disconnect blade switch. My thinking was that this emulates a power outage, inverter should shut down anyway then.
But what is the safest order of shut down?
And start up in exact reverse?
