Reposit Power and their Virtual Power Station

Canberra-based renewable energy startup Reposit Power are predicting their client base will double within a year, and hope to have their technology in 5,000 homes by 2020. Their ‘virtual power station’ model is one we’ve seen before (Enova’s community solar, AGL’s virtual power plant which is in advanced stages of trials), but we’re excited to see how Reposit’s system works. Anything that helps improve baseline power is great for Australian energy as a whole. 

Reposit Solar, the Reposit Box, and ‘Grid Credits’

Reposit Power have a ‘smarter, more intuitive way’ to control energy usage. According to their site, it typically costs approximately 4-6% on top of solar + storage, but these batteries will then be paid off in half the time as standard solar + storage. 

The system learns your energy usage patterns to feed back into the grid at optimum times. Every GridCredit you feed back into Reposit’s virtual grid represents a dollar off your bill – and the system automatically trades excess energy for GridCredits when the demand is at its highest. 

The system also uses advanced weather models to predict solar usage, factors in peak/offpeak tariffs, and will even charge your system overnight from the cheaper tariffs if it detects a probably energy shortfall for the next day’s peak hours.  It has an app which will display all information you need to know about the system, how much you’re saving, and how many GridCredits you are earning. 

Reposit Power Compatible Batteries

There are currently eight Reposit compatible batteries – they are available ‘pre-integrated’ from leading vendors or you can 

  • LG Chem Resu 6.4kWh
  • LG Chem Resu
  • LG Chem Resu HV
  • Fronius Solar Battery
  • GCL e-KwBe
  • Pylontech
  • Tesla Powerwall 1
  • Samsung All in One ESS

Reposit Power & Tesla Powerwall 2 Compatibility

Please note that there are no GridCredits on the Tesla Powerwall 2 as they won’t integrate with cloud / Internet only based control systems – given that it wouldn’t be able to function correctly if the Internet was unavailable. Since the Powerwall 2 is tremendously popular, this is a serious blow to Reposit Power’s ‘virtual power station’ – wonder if they’ll figure out a way to rectify this before the Tesla Powerwall 3 announcement
