AIMS 1200 Watt Inverter quandry

Tried to install a AIMS 1200 Watt full sine wave invert with automatic transfer switch this weekend..

Had 4 gauge cable for POSITIVE AND NEGATIVE, connected to the CONVERTER :POSITIVE coming right off the USE/STORE relay. Connected the NEGATIVE to the NEGATIVE bus bar.

Checked voltage, was running 12.7-12.6v DC

Pulled the AC leg that feeds the TVs/ETC (non-GFI) and connected to the inverter OUTPUT, (did not have anything turned on when trying to power up the inverter).

Connected ROMEX to RECEPTICLE Breaker, neutral bar and grounding bar and connected to inverter INPUT. (did not have shore power or generator turned on)


GREEN light on INVERTER/REMOTE CONTROL would come on, then go off in 1-2 seconds. This happed whether the AC INPUT/OUTPUT was connected or not..

Never could get the unit to stay on long enough to basically see if it would deliver AC power or not...

I tried GOOGLING this issue, but did not see anything like this..

I know some of you have this unit in your AXIS/VEGAS, just wondered of anyone else had run into this, and what the result was...

Hate having spent the whole weekend and end up in defeat...

Sounds like you have a connection issue
Follow the videos below from a fellow Thor Vegas owner who thoroughly explains the AIMs Inverter install process...

Part 1:

Part 2:

Part 3:

If this doesn't work for you, it may be a faulty AIMs Inverter that needs to be returned and replaced.

MO Mike, Did you figure this out yet? I have the same inverter. No problems with my install except they had one of my outlets (in the slide) wired separately (with a flexable wire) so I took me a while to figure out why it would not work.

Did you check the wiring again? Fuses?

You said "POSITIVE coming right off the USE/STORE relay". So your ran your own wire from this rely to the inverter? Did you install inverter near your fuse panel? I just used the 12v sorce at the fuse panel like "Two Trail Hikers" did in the youtubes posted above. Saves a lot of wiring.

You said "green light goes off" after 1 or 2 seconds.... Did it change to Yellow or Red? Make sure this phone line is connected tight to this remote and to the inverter. Push in or wiggle and see if it works and if it does replace phone line?

If no light at all - then no power going to inverter or remote switch. If the inverter is on it will be green (running your 120 outlets off of 12v battery) Yellow (on but your hooked up to shore power or genny is on so its bypassing battery) or RED which is a fault code (low battery or bad connection?).

Does the inverter light come on? Can you hear the fan run? Shoot me a PM if you like.

Guess the issue was a bad inverter...

AIMS sent me a replacement, wired it in with the same wiring that we had before and now have AC power on the batteries.

Transfer switch works great. Haven't tested on alternator power yet, but have no doubt that will work also. (just want to make sure that there is no issue running on 14.4 voltage coming from the engine)

Bye the way AIMS customer service/support is GREAT!

Mo_Mike, I agree. This inverter is the great as is customer service. I have a Vegas 25.5 so the inverter is under one of the twin beds. I even run a residential refrigerator with it and have no problems. It takes about 3 hours for the fridge to reach temperature and I still have 3 lights on the battery monitor.

I just returned from an 8 day trip.
I used inverter "always on", powering the fridge in most cases
When I boon-docked for extended periods of time, I moved fridge switch to "gas-only"

The biggest challenge was remembering all the switching needed when starting and stopping from place to place.
That is...
Am I plugged into shore power?
Am I using propane now?
Does the inverter need to be in "on" position right now?

That said, one time I left inverter-on powering the fridge while boon-docking for several hours (no Chassis engine or Genny running).

And I didn't draw down the battery bank past the 3 lights on the battery monitor

The nice feature is that you save $$$ on propane once the fridge is up to temp.

That was one reason we installed the inverter, to run the refrigerator without the propane being turned on while driving down the road.

Just feel safer traveling with the propane "off" until we stop to camp. And, hopefully, can run off the alternator without draining the coach batteries.

Thanks for all the replies on this.

Just tested with engine running and inverter was flawless. GAS/AC refrigerator ran fine on inverter power. (switched to automatic and propane valve off)

Dropped the alternator charging voltage on the coach battery circuit from 14.4 to 13.7 running the INVERTER/REFRIGERATOR combo, but at this voltage, the house batteries should still be charging fine while driving.

Definitely a HAPPY "rv" CAMPER here!
