•
When the battery SOC is below the DischargeEndSOC@Grid value or
fully discharged, the inverter will stop working and
local loads will be supplied from the grid.
•
Thanks to the on-grid operation, the switch from battery power, PV power
and grid power is automatic and seamless.
iii.
When grid fails,
•
When grid fails, the inverter will automatically disconnect from grid and
output power to the EPS port.
•
When battery is discharged to the DischargeEndSOC@EPS value, the
inverter will stop working and wait for the grid to recover or until there is
sufficient power from PV panels to charge the battery.
•
If grid failure can be a common occurrence in your area, you can adjust
the DischargeEndSOC@Grid higher to ensure there is battery power
available.
iv. You can also:
•
Set a schedule for the inverter to charge the battery using cheap off-peak
grid power.
•
Specify the daily working periods of self-use for inverter.
*1: The inverter can be set not to feed power into the grid. But a small amount
of energy will still inevitably be fed into grid due to unpredictable PV energy
change and load fluctuations.
*2: Firmware update may be required to support this function.
For on-grid self-use operating mode, one can set the discharge end
SOC@Grid as low as the battery allows (10% or 20% for example).
Please refer to your local battery technician for minimum discharging
end SOC.
