Daytime Off-Grid
■
PV Power > Load Power
: The PV power is preemptively supplied to the household load (Critical Load), and
then it charges the battery. Then, when the battery is fully charged, the inverter lowers the PV power to
generate as much as the household load (Critical load) power.
■
PV Power < Load Power
: If the PV power is less than the household load (Critical load + Main Load) power,
the battery discharges to supply the short energy to the critical load. If PV + battery power is less than the load
power, the inverter stops operating.

to the household load (Critical Load), the inverter stops operating.
