[RE-wrenches] APT Beaker

Sun Jul 19 17:22:01 PDT 2015

Possibly added after market, but I've seen quite a few APTs with QOUs 
used on the DC side.  I don't recall the exact mounting configuration.
In the days of DC loads, I would see the Heine's on the charge 
controller in, and then the QOUs used as PV inputs and DC load circuits.
I never sold the APTs; we built our own DC load centers until Outback 
and Midnite came along with saner pricing and better charge controllers.
