5kW PV System (Lithium) Solutions

Benifits

  • Backup power for lights & plugs
  • Lithium batteries
  • Scalable backup power
  • Low noise levels
  • Low maintenance costs
  • Reduces electricity bills
  • Truly renewable energy source

The Goodwe ES series bi-directional inverter is applicable with both on grid and off grid PV Systems.

It can control the flow of energy intelligently. During the day the PV plant generates electricity which can be provided to the loads, fed into the grid or charge batteries.

The energy stored can be released when loads require it during the night. Additionally the power grid can also charge the batteries (storage device) via the inverter.

Additional Info

  • The majority of new home energy storage technologies, use some form of lithium ion chemical composition. Lithium ion batteries are lighter and more compact than lead acid batteries. They also have a higher DoD and longer lifespan when compared to lead acid batteries. However, lithium ion batteries are more expensive than their lead acid counterparts.

Features

  • 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
