An on-grid inverter’s main job is to convert DC power generated from the PV array into usable AC power. Hybrid inverters go a step further and work with batteries to store excess power as well. In the developing world, hybrid inverters are more of a necessity to compensate for weak or intermittent grids or a lack of grid electricity all together.
Deye hybrid inverters include single phase 3kW/3.6kW/5kW/8kW and three-phase 8kW/10kW/12kW, and all of them adopts 48V battery. So, the solar energy storage system is safer and more reliable compared with high voltage battery system.
The Grid-interactive inverter consists of several hardware elements. The Grid-interactive inverter controls and monitors the connection of the electricity from the power plants. In addition, it also controls the disconnection of excess power from the plants. It ensures the dispatch of power at the peak time based on demand. In case of the disconnection of the surplus power, the inverter prevents blackouts, by switching the supply of electricity to the systems that demand it most. Grid-interactive inverter can also be used to switch the direct power supply from the main power plants to a Grid-to-Grid connection. Solution and service by Deye - China Hybrid inverter manufacturer
