The solar energy storage inverter can be used for both on grid and off grid solar systems, it integrates controller and inverter. During the daytime, the PV array generates electricity to provide power either to the loads, or  to the grid or charge the battery.  The battery can be charged either by PV power or by grid, the power stored in the battery can be released whenever the loads require it.  Moreover ,the inverter can give three phase unbalanced output accroding to set up, to make a most flexible power solution.

The solar power inverter is highly integrated with the digital technology, which can improve the MTBF and reliability of the system, the whole systems are controlled by an independent high-speed DSP chips which can ensure the stability and reliable operation.  Optional power: 40kW 60kW 80kW 100kW 120kW 150kW 200kW Battery voltage: DC192V/DC216V/DC220V/DC240V/DC360V/DC384V Battery type: Gel battery or Lithium-ion battery AC output voltage: three phase 208V or 380V/400V/415V

The  LiFePO4  battery  ESS  (Energy  Storage  System) includes LiFePO4  battery,  PCS.  The system includes  100KWh  LiFePO4  battery,  50KW  PCS,  liquid cooling system and  Fire protection system. The system includes BMS, PCS, and EMS.

This kind of solar system is integrated with wind turbine. Solar panel and wind turbine supply power to loads and charge battery together. It is suitable for those area with high-quality wind resources.

LV-BAT-R5.12Aa is a lithium battery with an operating voltage range between 45.6~56.2V. It is designed for residential energy storage applications and works together with a low voltage hybrid inverter.LV-BAT-R5.12Aa is not suitable for supporting life-sustaining medical devices.

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.
