[RE-wrenches] Anyone try the new SMA battery inverter with Automatic Backup Unit? Couple of questions.

Excited to use this and even more excited that one of our sales reps with a SMA system has offered to be our guinea pig! The ABU looks great - just got one to the shop today - it has transfer switch with full 200A capability, auto-transformer, easy inputs for BB-inverter, PV inverter, and smart me

Aw, one more Enphase / SolarEdge response. The "high voltage" DC is 350-380 volts and with the rapid shutdown capability now shipping standard with SE inverters, they go to 1 volt per optimizer when the AC grid is not present. By the way, that 1 volt per optimizer is a great way during instal

I'll give a different spin and of course each situation is different and to be judged on its own facts. Here in Texas, modules on a summer day don't typically perform to STC ratings and a DC/AC over-ratio is entirely appropriate. I've brought it up to 1.25 in some cases. I look at the economics
