In order to be able to feed back excess capacity into the grid, the solar inverter (along with all other generators) has to be synchronised in speed and phase ( think 2 engines running the EXACT same speed, and hitting TDC simultaneously) to the incoming supply.

With nothing to synchronise to, it has no choice but to shut down, in case it suddenly gets reconnected, unsynchronized.

Analogous to trying to control the speed of a MASSIVE engine, with your TINY engine, with a dog clutch.
