Today I installed a new Inteli-Power 9280 from Randy at Best Converter to replace the 70 amp Univolt in my Excella. It may be a bit of overkill, but I expect it to last for many years if 45 amp Inteli-Power I have in my Trade Wind is any example and will give me plenty of capacity for expansion.
The Univolt is still working (HUMMMMMM!!!), but I have bad memories about the failure of the one in my Trade Wind. The new Inteli-Power is
totally silent.
I have included photos of the old Univolt in place and the new Inteli-Power replacing it. I mounted the Remote Pendant just below the window above the covering that snaps into place and behind the curtains so the blinking LED status indicator won’t drive me crazy (ok, crazier

).
The sharp-eyed among you may notice that I mounted the new unit on top of rubber stoppers. This insures that no vibration can be transferred to the floor, not really much of a concern with the Inteli-Power though. It also spaces it up from the floor 15/16 of an inch in case any water were ever to get in. Of course, we all know that will never happen.

The rubber stoppers came from Home Depot. The large ones also make good isolation mounts for those 12-volt fans that make so much noise.
You may also notice that the Inteli-Power is plugged into the wall outlet using an adapter. The 80-amp Inteli-Power uses a 20-amp plug instead of a 15-amp one. Randy has discussed this in other threads. Apparently the RV industry commonly uses the 20-amp outlet for larger converters. Interesting choice since the maximum consumption for the Inteli-Power 9280 is 1,300 watts while portable electric heaters, which use a normal 15-amp plug, can consume 1,500 watts. It turned out that this adapter is very unusual. I was only able to find one online at music shops. I got mine locally at the Guitar Center here in Little Rock. It is a Furman ADP-1520.
The 6-gauge battery cable came from a local NAPA auto parts. I bought 6 feet and had about 18 inches left over.
Interestingly, the Inteli-Power weighs 7.67 pounds versus 39.5 for the Univolt.
