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

Hi all,

Has OutBack licked the multiple stacking UL listing yet? Can we hookup a
quad stack now to the grid? We would be looking at doing a 120/240 VAC
single phase setup with two inverters per leg.

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,

-jeff o
