Can’t find the Magnum Inverter on my 38GK

[Ezyracer]

I recently bought a used 2015 38gk and replaced the 12v 100ah battery with 2 6volt 225ah agm batteries wired in series. I thought it had the magnum MMS 1012 inverter since the magnum user manual was included in the the documentation pack. I get no AC power when shore power is disconnected so I suspect the inverter if I have one is not turned on. Does anyone know where it would be located? I checked behind the storage compartments and behind the Progressive fuse box/converter in the closet at the front door, also I don’t see any inverter remote control panels. Any help would be appreciated, If I don’t have the inverter, is the converter that is part of the fuse box sufficient to charge AGM batteries.

Thanks for your help.

Because of the nature of "Voltage drops"....Inverters usually are located close to the battery bank / source...Thick cabling runs from the batteries to the inverter.
This is not always the case....as smaller inverters can be located anywhere.

I would look carefully around the battery area....in your basement...and maybe behind the wall in your basement..

Does your unit have a generator or prepped for a generator? It could be mounted above the galvanized box for the generator. But should be close to the battery(ies).

Yes it has an Onan 5500k LP generator. I traced the pos/neg cables from the battery bank, one from each post goes to the generator and the thinner cables connect to a connection bar a on the back walk of the battery storage area next to the generator. I’ll check above the galvanized generator box r-time_soon suggests. I don’t see a battery temp sensor. I would think it would be located in an accessible area. Does anyone know if the inverter is standard or is it optional or only included in the Domestic refrigerator option.

The inverter is standard if and only if you have the Factory Residential Fridge. If you have a Dometic or Norcold fridge you wouldn't have an inverter.
Our inverter is mounted in the front basement area, street side, on the bulkhead between the basement and battery compartment. Also the Remote for controlling the inverter is mounted on the wall just inside the entrance door.
Good luck

You stated you bought the RW used with the inverter manual included, it sounds like the PO may have removed the inverter to install in their replacement RV or to recover a few bucks leaving you playing hide/seek for a non-existent inverter.

Thanks everyone for your help. Having the manual sent me on the hide/seek goose chase. I should have known when the manual for a Splendid 2100c was included but not the real washer dryer. Any recommendations for a 3000 watt pure sine wave inverter? Now that I upgraded the batteries I’d like to use them beyond my 12volts. The Magnums and Xantrex s are pricey, do you really get what you pay for with inverters?, - or can I go cheap with AIM, Renology or some other off brand? Thanks again.

What are you trying to do with an inverter ?...Big loads ? Full featured HD inverters (pure sine wave...so they play nice with sensitive electronics) with built in chargers are expensive....if your needs merit it a stand alone inverter (without charger etc...) maybe enough...if sensitive electronics is not an issue....again inverters (modified sine wave) can be quite affordable....The Magnum series inverters (pure sine wave) can be optioned up with a "full control" remote...auto gen start...etc....It adds up in a hurry...cabling...proper fusing...switching....bigger battery bank....

My goal is to be able to run one ac and the Norcold fridge off grid if I run out of propane and still have the lg tv and microwave work. If that can be accomplished with modified sine then I’ll be happy. I will need to charge a laptop, run a CPAP etc., I already have the Magnum remote control panel.

Run an AC unit off an inverter with a two battery ...bat bank ?

[Ezyracer]

I would expand the battery bank to 450ah, have not figured out how long the ac can run. May not be worth the trouble nor expense. I may be spoiled coming from a Beaver Motorhome with 600ah (6 coach batteries) with a Xantrex 4000k charger/inverter and 7500watt diesel Onan cummins generator that was able to run everything, so trying to create similar capabilities on the redwood. It was a 2001 model with halogen lights, everything original so was thinking I could get away with less power needs on a more modern coach. I don’t think the modified sine will work with Led lights, tv and printer. Thanks for your suggestions..
