    4.2.1 Whole home backup (requires sufficient inverter size) If the whole home is being backed up by the BushChook (all circuits - like what happens in an off-grid installation) then there is no need to separate the circuits in the switchboard. Also, the CT built into the BushChook inverter is used and there is no need for an external CT/Feed-in meter to be installed.
