I contacted Velit multiple times to get instruction when installing my unit, because the instruction manual is a joke. They finally sent me a updated PDF of the manual which did help with info like torque specs for the hold down bolts.

Same issues with these instructions. 😩

I'm curious what your power cabling looks like up to the batteries ? What did you do to get enough power back to run the new AC unit ?

@BradKoester 16 күн бұрын

The power cables follow the same path that the Maxair fan did and terminates at the circuit breaker under the bed. From there I upgraded the cables from the breaker to the batteries. This part was not fun.

can the ac run with the top popped up? How does it handle in the 95-100f temps?

Yes I run the AC with the top up with no issues. A few weeks ago we were traveling across the country and when we stopped in KS it was well over 100 F. It took it around 20 minutes to take it from over 100 to low 70s F. And it was able to maintain that for the remainder of the night.

Brad, I have a question. I contacted my Mission dealer to order the unit you purchased. They said Mission told them I would have to upgrade my WFCO unit. I know you swapped out your WFCO unit due to not recognizing lithium batteries. I was planning to run my ac unit using my battery bank. So I’m confused as to why I would have to change my WFCO to run the AC.

This is just a guess on my part…. The WFCO is a converter/charger, so it will provide DC power to charge your batteries and provide DC power for consumption. If they changed out the more recent trailers with a different WFCO, it might not produce enough DC power to keep up with the AC unit. The one that I changed out to has a slightly higher output, and is able to keep up with the AC unit’s needs as long as it is not on the highest/MAX setting (then it will draw from the batteries a little). Lastly, I contacted Mission Overland directly and did not do this through a dealer.

@@BradKoester Thank you for your reply. It was very helpful and you are correct in that the WFCO unit would need a higher output from 35amps to 40 amps. Thanks again.
