2 problems….
If you forget to turn off the mains, it could really make a lineman unhappy.
Most of these setups require a reprimand dangerous “ suicide cord”
I know enphase micro inverters have "anti-islamding" tech that disables output when they lose grid connection. I would expect any reputable manufacturer to also have the same tech.
I don't expect that for backup generators, but the proper way for them is via a transfer switch. You can wire in a properly made cable instead of a suicide cable. The transfer switch would prevent the inlet connector to the house from ever being live. (And since it is a proper cord from the generator, there would be no exposed ends coming from it.)
I agree on all points, but honestly I’d be pretty upset if I got a solar setup that didn’t work when the power was out haha
A LOT are like that though. They just get you a smaller bill by sending power bank to the grid, rather than making you grid-independent.
