Depending on your jurisdiction, particular in the EU, the micro inverters are usually not allowed to keep running if the grid fails. It of course still helps the grid to not fail in the first place by reducing load.
Our inverter (don’t know if its a micro or not) switches off but has some backup power plugs, where solar/battery power will be available in case of the grid going down. Good for the fridge and freezer.
That depends on the inverter and irs use case. The standard German ones are always connected to the grid and switch off when the grid fails. The can be complemented by a battery, which stores cheap self-produced electricity for later use. Depending on the type of electricity meter, they can also cause the meter to spin backwards. In the environment of Germany, which has a very very stable grid, all this makes good sense.
But you can also get inverters and batteries for “insular” systems, like for camping, which are not grid-connected. These will be more useful in countries where the grid is not stable. And then, you could combine both modes if the inverter circuitry allows that (or you switch inverters) - similar to an EV which is sometimes connected to the grid, and can act as a home battery, and sometimes not.
