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.<br>
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.<br>
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.<br>
