Calibration's
Impact on
Discharging
Batteries are
discharging at the
current load
power (the
discharged
battery energy
cannot be fed to
the grid).
1. When the
battery discharge
power is greater
than the load
power, the battery
discharges and
the surplus PV
power cannot be
fed to the grid.
The inverter
power is limited,
affecting the
energy yield.
2. If the battery
discharge power
is less than the
load power, the
PV power is
supplied to loads
at the same time.
Batteries are
discharging at the
maximum power,
and the total
power of PV and
batteries is less
than the power
limit at the grid-
connection point.
In the daytime,
the PV power fully
charges the
batteries. At
night, the
