[RE-wrenches] Battery Back-up and Grid Tie

Fri Apr 26 14:56:04 PDT 2013

The Ecogen is an excellent unit, but it is not cheap. For the price of the
Ecogen, you can get a 20KW Guardian packaged unit with ATS and not buy all
the batteries and inverters and switchgear.
If you only get very rare outages, how does it make sense?
