Hybrid inverter 3kw 5kw low voltage lithium-ion battery for home energy storage

This is 3kw hybrid inverter with battery cabinet, which can be use in our home load. Sunshine genertated electricity to the load meanwhile store the energy in the LiFePO4 battery, when national grid is stop work in the night.Battry will start work to offer energy to the load.When the battery power under its standard capacity, meanwhile no solar panel energy, the national grid will offer energy to the battery and load.
1. 3KW, 5KW hybrid inverter have the function with on grid and off grid inveter.
2. Single phase 5kw hybrid inverter with pylontech battery,connect with national grid, which can generate power for the load, meanwhile store the energy in the battery.
3. When no electricity and no solar panel energy to the load , the national grid will send the power to battery and load.
    Take full advantage of the solar energy, also can avoid to power outage.
    If the national grid don't accept the power , we can add the device to prevent the reverse flow.
4. The 5kw system, we suggest four battery (48v,50AH),which can store 9.6kwh.
