The nominal active power of an FHP system is determined by the total active power of the backup loads.

FHP capacity requirement: Total active power of backup loads ＜ FHP active power.

Overload protection may be triggered in the FHP system if the sum of active power of all backup loads is larger than the nominal active power of FHP system, when FHP works in off-grid mode without sufficient sunlight and the generators are not working. Overload protection may lead to power failure of some home loads.
