Goodwe ES 4.6kW Hybrid Inverter, 4.6KW Backup for sale in South Africa

4.6Kw Goodwe ES series Full Hybrid inverter is best suited to grid-connected PV systems: enhancing self-consumption and providing 4.6kW backup power to essential loads in the event of loss of grid. The Goodwe ES series bi-directional energy storage inverter can be used for both on-grid and off-grid PV systems.  During  the  day,  the  PV  array  generates  electricity which can be provided either to the loads, fed  into  the  grid  or  charge  the  battery,  depending  on  the  economics  and  set-up.  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.

  • It can intelligently control the flow of energy.
  • Both MPPT charge controller and inverter are fully integrated
  • Intelligent battery management function.
  • Capable of being grid-interactive or grid-independent.
  • Compatible with various Li-Ion battery types.
  • 2 x MPPT inputs with a Max of 6500Wp.
  • 100A Battery charger.
  • 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.
  • When using Lead-Acid battery technology with the ES/ EM Inverter range, Goodwe does not take any responsibility if the system performs below expectation

Summary
As a product intended for the new installation of PV storage generators, EM/ES series are aimed for boosting self-consumption in areas with high electrical rate and a relatively low FIT. For areas and regions where peak shaving can be applied and feed-in-power is restricted, this system would be a good fit.

Functional Introduction
Increasing Self-Consumption: During the day, the electricity from the PV array is used to optimize self-consumption. The excess is used to recharge the batteries and can be released to the loads at night. The highest proportion of self use is up to 95%.

Peak  Shaving:  By  setting  the  charging  and  discharging  time,  the  battery  can  be  charged  using  the  lower  electrical  rate  and  discharged to loads when there is a high electrical rate.

Power  Supply  for  Important  Loads:  Connected  to  the  backup  side  of  the  inverter,  loads  such  as  refrigerators,  routers,  lamps,  computers  and  other  small  appliances  can  be  powered.  When  grid  fails  the  system  automatically  switches  to  back-up  mode  within milliseconds.
