Parameter Description Value Range
Priority of
excess PV
energy
● Charge: When the generated PV energy
is greater than the loads, excess PV
energy is used to charge the batteries.
After the maximum charge power is
reached or the batteries are fully
charged, the excess PV energy is fed to
the grid.
● Fed to grid: When the generated PV
energy is greater than the loads, the
excess PV energy is preferentially fed to
the grid . When the inverter output
power reaches the maximum value, the
excess energy is used to charge batteries.
This setting is applicable to the scenario
where the FIT is higher than the
electricity price. Batteries are used only
for backup power.
● Charge
● Fed to grid
Allowed charge
power of grid
(kW)
Indicates the maximum charge power
allowed by the grid. The value is
determined by the local grid company. If
there is no requirement, the value is the
maximum charge power of the ESS by
default.
