[RE-wrenches] Equipment ideas for very large residential PV and battery backup

[Peter Giroux]

  Is this a commercial project? If so depending on the incoming voltage, Fronius Primo or Symos for the grid tied portion and Outback radians for the battery side ( can stack up to 8 per Mate and hub ) . There is a company called Sol-Ark that has a great true Hybrid but they are still working on stacking inverters.

  Re batteries, LG if they ever bring their 48 volt battery to the US, SimpliPhi or Blue Planet out of Hawaii. With Outback you can use their 12 volt output ( with a relay from Grainger ) to trip off the Neutral on the Fronius inverters if the battery voltages get too high on an AC Coupled application. No matter who you use there will be a few challenges but hey, if it was easy everyone would think they could do it. Sounds like a fun, challenging project, enjoy.

  Hi Wrenches,


  We have a new potential client who wants a 60 kW PV system and a battery backup system with 200 kWh of storage. The system will be grid tied and the client insists on some sort of lithium battery technology and doesn't want Tesla. For such a ridiculously large system, what kind of equipment would you recommend? I'm thinking maybe Sunny Islands with Blue Ion LiFePO4 batteries?


  Best, August
