I know I saw this a while back but I need sonic's contact information. I have a power inverter that was replaced twice on my 04 31ss and it has a 3 year warranty but they will not warranty it because they say sonic installed too small of a unit to handle the a/c. I know it is a long shot but I want to send them the bill and letter from Xantrax stating the unit was not suffient for what it was intended to do. Thanks in advance.

The number on the web site answers as First Derivative.

With the right size inverter, how long will the AC actually run? I remember reading some threads and if I remember correctly, it really sucked up the juice from the batteries quick. Some guys were using golf cart batteries which really weigh a lot...

Spend $800-$1000.00 ( depending on where you get it ), & get a Honda EU2000 Genny. Small, light weight & will run everything.

I wouldnt expect the bats to run the too long. The AC draws alot on start up & cycle. doubt you would get more than a couple hrs before they were drained. Not good on the bats, inverter or AC unit I would think.

From the last pics in the uncensored section, I know why you want to spend some time in the cabin with the AC crankin !

If you are going to run an a generator on your transom, you need to read the thread Gen Sets Are Dangerous from back in June. Friends of my brothers died in their boat while running a generator to power the A/C.

It will run about 3 hours I have 4 batteries and they shut off before they run all the way down. I do not use the a/c very often without shore power. I do not recommend this setup for anything more that running the a/c while the little woman get's her hair fixed or makes a frozen margarita. Or for a little one on one time away from the group. I sent the info to Bruce at sonic we will see what they have to say. Thanks
