Markets and Application Scenario

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 Solar first Solar first Max use solar energy and battery power
Rural area : Utility grid unstable Provide backup power when power outage Solar first Solar first Always keep battery full and standby
