only detect it after a restart!
3.4.4 Connection to AC Voltage
On the power side the AC voltage is connected to the automatic circuit breaker F2. If
there is only one electric circuit this can be directly supplied by the Sunny Island. If
there are additional devices feeding the grid, such as wind generators, separate cir-
cuits and thus an external distribution is recommended.
