This is a multi-function inverter/charger, combining functions of inverter, solar charger and battery charger to offer uninterruptible power support with portable size. Its comprehensive LCD display offers user-configurable and easy-accessible button operation such as battery charging current, AC/solar charger priority, and acceptable input voltage based on different applications.
There are three working modes：Standby mode/Power saving mode; , Fault mode, Line Mode,
Standby mode/Power saving mode :
Standby mode: The inverter is not turned on yet but at this time, the inverter can charge battery without AC output.
Power saving mode: If enabled, the output of inverter will be off when connected load is pretty low or not detected.
No output is supplied by the unit but it still can charge batteries.
Fault mode:
Errors are caused by inside circuit error or external reasons such as over temperature, output short circuited and so on.
PV energy and utility can charge batteries. Utility can power loads when the unit starts up without battery.
Line Mode:
The unit will provide output power from the mains. It will also charge the battery at line mode.
Battery Mode:
The unit will provide output power from battery and PV power.
PV priority mode：
When PV energy and battery will supply power to load. When PV energy is invalid , Load will be supply by mains.
In this output mode, Solar energy can be maximally used, battery will also maintain high charging level.
This mode is suitable for areas with stable power grid.
Mains supply priority mode ：
Load will by powered by Mains priority . when mains power is invaild ,then the load will be powered by Inverter (Battery)
In this output mode, the system will work as backup UPS.
It suitable for area with unstable power grid.
Inverter priority mode：
Load will be powered by Inverter(Battery), When battery is low ,then load will be supply by mains .
In this output mode, Battery energy will be use maximally.
This mode is suitable for areas with stable power grid.

Off grid inverter works in many place, suitable for different utility grid conditions, you can use the inverter in different way.
In urban area, with Stable utility grid power but electrictiy price is high. In this suitation, off grid solar system can help max reduce electritiy bills.
In rural area , with Unstable utility grid power and need backup power supply when power outage. In this suitation, off grid solar system can provide stable power supply.
| Typical Scenario | First concern | Charging Mode setting | Output mode setting | Method |
| urban area : Utility grid stable But electricity price is high | Reduce electricity bills | PV Priority | Inverter Priority | Max use solar energy and battery power |
| Rural area : Utility grid unstable | Provide backup power when power outage | PV & Mains mixed charging | Mains Priority | Always keep battery full and standby |
