1604
Manual generator stop
1605 Manual error acknowledgment of generator error
1606 Generator requested
1607 Generator started in current-controlled operation
1608 Generator stopped in current-controlled operation
1609 Grid request due to low battery state of charge
1610 Release of grid disconnection due to sufficient battery state of charge
1611 Grid request due to power limit being exceeded
