Goodwe ES Series 5kW Hybrid Inverter


GoodWe ES series GW5048-ES 5kW Hybrid Inverter bi-directional energy storage inverter is compatible with both on-grid and off-grid PV systems. It can control the flow of energy intelligently. During daytime, the PV plant generates electricity which can be provided to the loads, fed into the grid or charge the battery. The electricity stored can be released when the loads require it during the night. Additionally, the power grid can also charge the storage devices via the inverter.


  • Both MPPT charge controller and inverter are fully integrated.
  • Intelligent battery management function.
  • Capable of being grid-interactive or grid-independent.
  • Compatible with various Lead-acid and Li-Ion battery types.
  • IP65 dust-proof and water-proof rating.
  • 45°C full-load output.
  • Monitoring of inverters is free via computers or mobile phones and extremely easy to use.
  • Fanless, low-noise design.
