The system is a flexible intelligent hybrid inverter, using solar energy, ac power supply, and battery power supply, to provide continuous power supply. This system is a simple and intelligent solar energy storage system, users can store energy in the battery for use at night, or according to the need to set their own use time. Photovoltaic energy, battery storage energy and power priority can be programmed and set by themselves. At night or during power outages, it automatically uses up the battery's remaining power, reducing its dependence on the city's electricity.


2. Work mode

2.1 With sufficient solar energy, solar energy can 

simultaneously power the load, charge the storage

 battery, and integrate the excess power into the 

grid. When the battery and load are not used, t

he solar power is all integrated into the grid


2.2 When photovoltaic power generation is low, 

the power supply will not work.

The battery powers the load until the battery

 consumption is very low, and the load 

uses the city grid.



When there is a long-term shortage of main 

power or no main power, the system can be 

used as off-grid inverter to provide continuous

 power to the load. Mainly solve remote areas or

 field ac power applications
