If no PV modules are installed or the system has not detected sunlight for at least 24 hours,
the minimum end-of-discharge SOC is 15%.
Description
● Charge: When the PV power is greater than the
load power, the surplus PV energy is used to
charge the batteries. After the maximum charge
power is reached or the batteries are fully charged,
the surplus PV energy is fed to the grid.
● Fed to grid: When the PV power is greater than the
load power, the surplus PV energy is preferentially
fed to the grid. When the maximum output power
of the inverter is reached, the surplus energy is
used to charge the batteries. This setting is
applicable to the scenario where the feed-in tariff
(FIT) is higher than the electricity price. The
batteries are used only for backup power.
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.
