Inverter Input Mode
1.
Go to
Hybrid Setting > GEN Port
page and choose
Inverter Input
.
Inverter Input Mode:
Under this mode, the GEN Port works as an input port from other grid-tied inverter.
The grid-tied inverter should also support derating output power according to the output frequency.
Note: The capacity of grid-tied inverter should be less than that of hybrid inverter.
2.
All parameters have been set by default.
Battery SOC Of Inverter On (V):
Battery SOC below which the Inverter powers on and starts charging
the battery.
Battery SOC Of Inverter Off (V):
Battery SOC above which the Inverter powers off and stops charging
the battery.
AC couple Frequency high (Hz):
This parameter is used to limit the output power of grid-tied inverter
when the hybrid inverter works under off-grid mode. As the battery SOC reaches gradually to the setting
value (Off), during the process, the grid-tied inverter output power will decrease linear. When the battery
SOC equal to the setting value (Off), the system frequency will become the setting value (AC Couple
Frequency high ) and the grid-tied inverter will stop working.
The default values of
Inverter Input
are as below:
3.
If the values are set as described above, the situations are as follows:
Under off-grid mode, when the Battery SOC ≤ 80%, the GEN port function will be enabled and Inverter
Input will be ON. When the Battery SOC ≥ 100%, the GEN port function will be disabled and Inverter Input
will be OFF. When the battery charge power lower than the grid-tied inverter output power, the hybrid
inverter will increase the output frequency to maximum 52Hz. Then the grid-tied inverter will work in
limited power mode.
Under on-grid mode, the grid-tied inverter works as normal regardless of battery capacity.
