PV Power Preferred is displayed only when the PV+ESS system and charger are connected
to the same plant.
In addition to the power supplied to home appliances and ESS, if the surplus
PV power is greater than the setting of Surplus Power to Start Charging, the
charger starts charging.
In the PV Power Preferred mode, after the charger starts charging, the actual
charging power is related to the surplus PV power and the setting of Max
Charging Power from Grid.
– When the surplus PV power is greater than Max Charging Power from
Grid, the charger uses the surplus PV power to charge the vehicle.
– When Max Charging Power from Grid is greater than the surplus PV
power, the charger charges the vehicle at Max Charging Power from
Grid. The deficiency is supplemented by the power grid.
The minimum charging power of a single-phase charger is about 1.38 kW*.
You are advised to set Max Charging Power from Grid of the single-phase
charger to a value greater than 1.38 kW. Otherwise, charging will be
interrupted when the PV power is low.
