Solar Arc Fault ON:
This is only for US.
System selfcheck:
Disable. this is only for factory.
Gen Peak-shaving:
Enable When the power of the
generator exceeds the rated value of it, the inverter will
provide the redundant part to ensure that the generator
will not overload.
DRM:
For AS4777 standard
Backup Delay:
0-300)S adjustable
BMS_Err_Stop:
When it is active, if the battery BMS failed
to communicate with inverter, the inverter will stop
working and report fault.
Signal ISLAND MODE:
when "signal island mode" is
checked and the inverter connects the grid, the ATS port
voltage will be 0. When "signal island mode" is checked
and the inverter disconnected from the grid, the ATS port
voltage will output 230Vac voltage. With this feature and
outside NO type relay, it can realize N and PE disconnection
or bond.
More details, please refer to le side picture.
Generator input rated power: allowed Max. power from diesel
generator.
GEN connect to grid input: connect the diesel generator to the
grid input port.
Smart Load Output: This mode utilizes the Gen input connection
as an output which only receives power when the battery SOC
and PV power is above a user programmable threshold.
e.g. Power=500W, ON: 100%, OFF=95%: When the PV power
exceeds 500W, and battery bank SOC reaches 100%, Smart Load
Port will switch on automatically and power the load connected.
When the battery bank SOC < 95% or PV power < 500w, the
Smart Load Port will switch o automatically.

Smart Load OFF Batt
• Battery SOC at which the Smart load will switch o.
Smart Load ON Batt
• Battery SOC at which the Smart load will switch on. Also, the PV input power should exceed the setting value (Power)
simultaneously and then the Smart load will switch on.
On Grid always on: When click "on Grid always on" the smart load will switch on when the grid is present.
Micro Inv Input: To use the Generator input port as a micro-inverter on grid inverter input (AC coupled), this feature will
also work with "Grid-Tied" inverters.
Micro Inv Input OFF: when the battery SOC exceeds setting value, Microinveter or grid-tied inverter will shut down.
Micro Inv Input ON: when the battery SOC is lower than setting value, Microinveter or grid-tied inverter will start to
work.
AC Couple Fre High: If choosing“Micro Inv input”, as the battery SOC reaches gradually setting value (OFF), During the
process, the microinverter output power will decrease linear. When the battery SOC equals to the setting value (OFF),
the system frequency will become the setting value (AC couple Fre high) and the Microinverter will stop working.
Stop exporting power produced by the microinverter to the grid.
Note
: Micro Inv Input OFF and On is valid for some certain FW version only.
AC couple on load side
: connecting the output of on-grid inverter at the load port of the hybrid inverter. In this
situation, the hybrid inverter will not able to show the load power correctly.
AC couple on grid side
: this function is reserved.
Note
: Some firmware versions don’t have this function.
