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:
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.
| Operating Mode | Built-in Optional Mode | |||
| Charging Mode | Standby mode/Power saving mode | Fault mode | Line Mode | |
| Output Mode | PV priority mode | Mains supply priority mode | Inverter（battery）priority mode | |
Off-grid storage inverter works in many places, suitable for different utility grid conditions. You can use the inverter in different ways:
In urban areas, with stable utility grid power but electricity prices are high. In this situation, an off-grid solar system can help maximize electricity bill reduction.
In rural areas, with unstable utility grid power and the need for backup power supply during power outages. In this situation, an 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 | Battery mode | Inverter priority | Max use solar energy and battery power |
| Rural area : Utility grid unstable | Provide backup power when power outage | Battery mode | Mains priority | Always keep battery full and standby |
