7 ESS Maintenance
Impact of Forced
Check 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. When the battery
discharge power is
less than the load
power, the PV power
is supplied to loads
at the same time.
