Auto Start Charge: Percent SOC below Auto Start Charge, system will AutoStart
to charge the battery bank from the generator(or the power grid).
Exit Charge: Percent SOC reach Exit Charge, system will stop charging the battery bank from the
generator(or the power grid).
Charge Current: Charge rate of Charge Current from the attached generator(or the power grid) in
Amps.
Gen Charge Enable: uses the gen input of the system to charge battery bank from an attached
generator, it is the main switch apply to all system work mode.
Gen State Signal: Normally open relay that closes when the Gen Charge Enable is active.
Gen Max Run Time: It indicates the longest time Generator can run in one day, when time is up, the
Generator will be turned off. 24H means that it will not shut down all the time.
Note: The setting method about Grid is the same to the Gen in this page.
Note: if the setting is conflict, The Grid priority is higher than Gen in all system work mode.
Lithium protocol: This is BMS protocol. Please reference the document(Approved Battery).
Bat Shutdown: It indicates the inverter will shutdown if the SOC below this value.
Bat Low Batt: It indicates the inverter will alarm if the SOC below this value.
Bat Restart: It indicates the inverter will restart if the SOC above this value.
Bat Constant V: It indicates the Battery will charge to this value when Bat Mode is Use Batt V.
Bat Float V: It indicates the Battery will charge to this value after battery voltage reachs Bat
Constant V and charge current is below than 5A last for 10min in Bat Mode is Use Batt V.
System Work Mode:
Selling First: This Mode allows hybrid inverter to sell back any excess power produced by the solar
panels to the grid. If Time Of Use is active, the battery energy also can be sold into grid.
The PV energy will be used to power the load and charge the battery and then excess energy will
flow to grid.
Power source priority for the load is as follows:
1. Solar Panels.
2. Grid.
3. Batteries (until programable SOC discharge is reached).
Zero Export To Load: Hybrid inverter will only provide power to the backup load connected. The
hybrid inverter will neither provide power to the home load nor sell power to grid. The built-in CT
will detect power flowing back to the grid and will reduce the power of the inverter only to supply
the backup load and charge the battery.
Zero Export To CT: Hybrid inverter will not only provide power to the backup load connected but also
give power to the home load connected. If PV power and battery power is insufficient, it will take
grid energy as supplement. The hybrid inverter will not sell power to grid. In this mode, a CT is
needed. The installation method of the CT please refer to chapter xx CT Connection. The external
CT will detect power flowing back to the grid and will reduce the power of the inverter only to supply
the backup load, charge battery and home load.
Solar Sell: “Solar sell” is supplement for Zero Export To Load or Zero Export To CT: when this item is
active, the surplus PV energy can be sold back to grid too. When it is active, PV Power source
priority usage is as follows: load consumption and charge battery and feed into grid.
Dispatch Mode: Receive power scheduling instructions by the energy management system (EMS), if
ticked, inverter will charge or discharge base on the Active Power setting.in Dispatch Mode, the
battery power can be sold into grid.
Active Power: the charge power(Active Power greater than 0) or discharge power(Active Power less
than 0) in the Dispatch Mode.
Max. Sell power: Allowed the maximum output power to flow to grid.
Zero-export Power: for Zero Export To Load or Zero Export To CT, and the “Solar sell” is not active. it
tells the grid output power threshold to ensure the hybrid inverter won' t feed power to grid.
Energy Pattern: PV Power source priority.
Batt First: PV power is firstly used to charge the battery and then used to power the load. If PV
power is insufficient, grid will make supplement for battery and load simultaneously.
Load First: PV power is firstly used to power the load and then used to charge the battery. If PV
power is insufficient, Grid will provide power to load, but neither the battery power to load nor the
Grid charge to battery.
Note: Batt First and Load First are suitable to Selling First(Time Of Use is not active) and Zero
Export To Load and Zero Export To CT.
