SX-HSI Series Inverter can connected with PV panel, AC mains ,Battery and Load to make a off grid solar storage system.

SX-HSI Series Inverter Intelligently switches between using solar power,battery storage and grid power. It can provide low costs energy for power stable places or stable power supply for grid unstable areas.

There are four charging modes:PV priority ,mains power priority, PV and mains mix charging,only solar power.

Three output modes: PV priority output, Mains priority output, Inverter (battery) priority output.

Charging Mode

PV Priority : 
Battery will charge from PV priority. when PV energy is unavailable(PV panel output voltage under PV operating voltage 120V)
then battery will be charged from mains . 
This charging mode make full use of solar energy in the daytime.
It is suitable for areas with relatively stable power grid and relatively expensive electricity price

Mains Power Priority: 
Battery will charge from mains, only when the mains supply is invalid, PV will start to charge battery. 
This charging mode will make battery always keep full. 
It is suitable for areas with unstable utility grid power and need backup power supply when power outage

PV and Mains Mix Charging:
When PV energy is sufficient , PV will charge battery priority, when PV energy is insufficient
(PV Charing current is less than charging current setting in the inverter), then PV and mains will charge battery at same time.
In the charing mode ,battery can be fully charged in fastest way. It is suitable for the area with unstable power grid, battery will use as backup power supply.

Only Solar :
Only use PV energy to charge battery.
This charging mode can save the electricty bills at most.
All the battery energy are from solar energy. It suitable for areas with good light condition or without mains connection.

Output mode

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

Operating Mode Built-in Optional Mode
Charging Mode PV priority Mains power Priority PV and main mix charging Only solar
Output Mode PV priority mode Mains supply priority mode Inverter(battery)priority mode

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 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

24V 3000W, 24V 3500W, 48V 3300W, 48V 5500W, 48V 5500W(Parallel OK), 24V 3000W, 48V 5000W
