Application Settings

• EPS Voltage Set(V): Set voltage of the inverter’s output.

• PV Grid Off: If the customer wants the system to have Off-Grid functionality without in-

stalling any batteries, please enable PV Grid Off. Please note, in this situation the Off-Grid en-

ergy is supplied by solar and is not stable. We suggest the customer install battery/batteries to

keep the EPS/UPS output voltage stable if they want to have Off-Grid function. (Allow system

to access the Off-Grid mode when only solar input is available)

• Power Backup: If Power Backup function is Enabled, the LOAD terminal will maintain output

when AC is interrupted. You can set “Power Backup” via web or “Off-Grid Output” by LCD.

(When enabling this mode, the inverter’s output will be uninterrupted).

• Seamless EPS Switching: When power is interrupted, the inverter will turn to EPS mode

seamlessly unless there is a grid voltage fluctuation issue; in which case, we suggest you set to

“Disable” to avoid misjudgment.

• Grid Sell Back: In some cases, the customer cannot feed energy into grid. If the customer

does not want to feed energy to grid, you can disable the Grid Sell Back function.

• Grid Sell Back Power(kW): If Grid Sell Back function is enabled, you can adjust the power

limitation to feed into the grid.

• Fast Zero Export: Normally the inverter will adjust output power every 5 seconds to avoid

export. If Fast Zero Export is enabled, the inverter will adjust output power accordingly.

• Max. AC Input Power(kW): The inverter can adjust the charge power based on the detected

inverter’s load consumption and max. AC Input power limitation.

• PV Arc: Only available for the US model. The inverter will detect when there is a PV input

Arc Fault and protect the inverter from an Arc Fault.

• PV Arc Fault Clear: Clear the records of PV Arc fault.

• Run Without Grid: Enable for Off-Grid operations.

• RSD: The rapid shut-down detection of the PV inputs.

• Normal/Standby: “Standby” is used to set the system into standby mode, stopping feed in,

charge and discharge. “Normal” is used to set the whole system to auto run status.

• Restart Inverter
