Video: Installing a Magnum Hybrid Inverter in our Airstream
We just got done installing a Magnum Hybrid Inverter in our Airstream. It was such a relief to find that chase under the floor, it made the install SOOOO much easier. Install Video

Why didn't the Dimension Energy engineer want to use the transfer switch built into the Magnum itself? Is using an external transfer switch going to interfere with the hybrid's load-support feature?
Fantastic question. It's fun hearing from people who know a thing or two about this technology!
So... we actualy didn't bypass the internal transfer switch. I was going to explain it in the video, but it felt long-winded. The factory Airstream transfer switch is for the two power inputs - one on the street side, and one on the front of the trailer (for a generator). The Airstream transfer switch lets either input work, so we kept that.
If you're plugged into both a pedestal and you're running your generator (who would do that?, the transfer switch will give one priority and block the other one. (I can't remember which one it gives priority to). We easily could have disabled one of the inputs and bypassed the Airstream transfer switch, but I wanted to keep it as close to stock as possible. If we ever sold it the poor new owners would have no clue what we did.
After the Airstream factory transfer swtich, the power goes into the inverter's internal transfer switch.
Thanks! That makes sense, didn't know there were two power inlets.
