3.3 Working Mode Introduction
3.3.1 On Grid Self-Use Working Mode (Default)
The on grid self-use operating mode is recommended for when the system is
installed in an area with a stable grid. The purpose is to increase self- consumption
of clean PV energy. When Inverter is set to work in this mode:
During daytime and there is sufficient PV Power
•The PV energy is used to supply local loads as first priority andthen charge the
battery, excess energy will be fed intogrid*1*2.
•When battery is fully charged, PV energy is supplied to the local loads and fed
into grid*1*2.
During nighttime or there is not sufficient PV Power
•The battery is discharged to provide energy to loads. If there is not enough
power from the battery, the unmet power will be supplied by the grid.
•When the battery SOC is below the DischargeEndSOC@Grid value or the
battery is empty, 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.
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.
 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.

10
*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 Working 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.
3.3.2 Off Grid / Back-up Working 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 Working Mode:
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.
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 SOC reaches the EPS restart value.
When working in this mode:
•The max power*3 from the EPS port is limited by inverter type, battery type
and battery SOC.
•A larger battery is always recommended for off grid / back up configuration.

11
You should never discharge the battery too deeply to avoid it “Running Flat”.
•When there is an overload or short circuit fault, the inverter will stop working
and an alarm will sound. It will try to restart several times before shutting down
completely. Turn off or unplug load to remove the short circuit fault or overload
as soon as possible.
*2: Firmware update may be required to support this mode.
*3: Please be noted that refrigerators, air conditioners, water pumps and etc., demand
a large start up currents and may trip EPS overload protection. Be sure not to connect
too many of this kind of load to avoid frequent system shutdown and restart.
3.3.4 Declaration for backup loads
Hyper series inverter is able to supply a continuous 5000VA output (max 5500VA
for 10s) on EPS side. Inverter will shut down under full loading with high ambient
temperature if grid is absent.
Accepted loads as below:
• Inductive Load: Max 1.5KVA for single inductive load, max 2.5KVA for total
inductive load power.
• Capacitive load: Total capacitive load (like computer, switch power etc.) power
≤3.0KVA
(Any load with high inrush current at start-up is not supported on EPS circuit)
For off-grid / back-up Working Mode, one should set a higher
DischargeEndSOC@Grid value (above 50% for example). So that there will be
some energy in battery when a grid failure occurs.
