[RE-wrenches] Grid-Connect Inverter with battery, AND auto backof f?

[Joel Davidson]

Hi Jeff,

Was that the Living Center PV system configuration before or after the flood and fire? Was the Fetzer Winery PV system also with 2 meters?

Cheers,
Joel

  Hi Joel,

  The system I designed at the Real Goods Solar Living Center was been grid-tied and on battery back-up for 13 years now, goes back to the non net-metering days and 2 meters. I did a whole "house" back-up with 2 SW5548's on the lighting panel and 2 SW5548's on the plug-load panel. PV is about 11kW and battery is good for 8 hours of store back-up. We kept one office off of back-up so we would know when a power failure occurs and energy use could be cut back a bit. All the usual problems of you see over 13 years - inverter issues, batteries not liking a life in float, CC failures and so on, but agin nothing that we would not experience on a typical o-t-g system.

  Take care old buddy,
