Change to more efficient energy and water systems



YellowDot Energy has designed and built an innovative off-grid solar–diesel hybrid power plant on a cotton farm in Moree NSW. This power plant allows the cotton grower to pump high volumes of irrigation bore water while reducing diesel consumption by up to 60%.



Key features

  • Integrates power from solar PV and a diesel generator via a high capacity variable frequency drive
  • Capable of operating 24/7 in hybrid mode or during daylight hours in solar-only mode
  • Pumping up to 4ML per day during peak season
  • Electronic control system manages the generator, PV, drive output and the hybrid integration 
  • DC optimised PV modules provide power control from the solar array
  • Multiple sensors and modem communications provide monitoring and remote systems control
  • Submersible three phase electric pump  

 Projected outcomes

  • 890 ML pumped per year
  • Up to 4ML per day during peak season (hybrid) and up to 1.6ML per day off season (solar only)
  • Annual diesel saving 40,760L which is a 60% reduction on original diesel engine
  • Reduced annual maintenance cost


  • 70kWp of solar PV
  • Ground mounted, north facing array
  • PV modules include Tigo DC optimisers
  • 45kW ABB Variable Frequency Drive
  • ABB PLC control system
  • 100Ah battery UPS for control system including solar and generator charging capability
  • Himoinsa 60kVA diesel generator with modbus connected control panel
  • Submersible pump manufactured and installed by Condamine Drilling!irrigation-pumping/g3pxr






A 30kw Grid Connect System with Generation Management was commissioned in Menzies in November 2015 for power producer SOLARZONE (WA) within 7 days by Global Protection Systems (GPS) providing approximately 125units of energy per day - a total annual carbon reduction of 41 tonnes.

GPS provided a turn key solution which included a Battery Control Room - heavily insulated the Control Room is built to withstand the harshest of conditions within Australia. Built in Perth and transported upon completion!

This approach allows us to supply clients in the most remote areas within the Country.

The Generation Management component was been designed by Yellow Dot Energy.
