• PV Power > Load Power : The PV power is preemptively supplied to the household load (Critical
load + Main Load), and then it charges the battery. If PV energy remains, it is operated according to
the operation mode as below.
- Self consumption mode : The remaining PV energy is supplied to Grid.
- Zero export mode : Q.VOLT decreases the PV generation amount.
•
PV Power < Load Power
: If the PV power is less than the household load (Critical load + Main
Load) power, the battery discharges to provide the short household load energy. If the PV + battery
power is less than the load power, the short load power is supplied from the grid system.
