Operating Mode

7.2  Off-Grid Mode

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.

Nighttime Off-Grid

While the battery discharges, it supplies energy to the load. If the battery power is not enough to supply energy 

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