•
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.
4.4.2 Off Grid / Back-up Operating Mode
*3
For systems installed in area with a weak grid or even without grid,
the inverter should be working in off grid / back-up operating mode:
i. When grid or diesel generator is available,
•
When the battery is below the DischargeEndSOC@Grid value,
it will be charged firstly from PV and secondly from grid at the
max allowable current.
•
When the battery is above the DischargeEndSOC@Grid value,
it will be charged by excess PV energy and will discharge if
the PV power is not enough to support the loads.
ii. When grid or diesel generator is not available,
•
When there is enough energy stored in the battery, the EPS
port will export power to support local loads firstly from PV. If
there’s excess PV energy, it will be used to charge the battery.
Otherwise battery will be discharged to feed the load.
•
When the battery SOC is below the DischargeEnd SOC@EPS
value, the inverter will disconnect power to the EPS port. All
energy from PV will be used to charge the battery until the
