Where is the MPPT? 2022 Interstate 19

[DavePDX]

Does anyone know where the Victron MPPT Bluesolar MPPT 150/35 is located on an 2022 Interstate 19?

Airstream told me it was under the curb side ottoman, but it's not there, unless it's well hidden. Anyone know the correct location? TIA

Apparently Airstream puts these devices all over the place. I'm not sure how your setup is but a few things are the same unless someone can chime in that has found it and provide you with the exact location.

With some wire chasing you'll probably be able to find it. You'll need to check where all your components are centrally located. The MPPT has the solar wires going in to it. You have a Green and Yellow wire and these are usually marked with Solar + & - on them. They come from the solar panel to the MPPT. You can also chase a wire from your thermal fuse buss bar (these are the square resettable looking fuses) where you should have a 40a fuse with a wire going to the charge controller.

The thermal fuse buss bar looks like this in the pic. Good look hunting.

Thanks much, those clues should be helpful!

Sorry, don't know about an Interstate 19, but my 2022 24X has the MTTP under the drivers seat colocated with the DC-DC converter, and the trickle charger for the chassis battery.

Ok, so this is incorrect. This is the MPPT for the chassis battery (one 100w solar panel).

The MPPT 150/35 is under the curb side bench all the way in the back behind a side panel.

Thanks for the replies. I'm currently traveling and haven't had a chance to take another look, but I'll report back when I do.

emike,, do you mean under the curb side ottoman or the sofa bench? And when you say "behind a side panel", do you mean between the outside of the van and the inside of the van?
I did see a black cover located against the outside wall of the van, under the stove cabinet when I removed the curb side ottoman (photo attached), but it didn't come off easily, so I didn't expore that further. Toward the rear of the ottoman cabinet is the wheel well and I didn't see anyplace it could be hidden there.

Thanks so much for the assistance!

For the Interstate 24x, it's under the curb side bench. We don't have a sofa or ottoman.

Thanks for the photos and reply. Alas, the 24x seems to be a different beast from the I19. The dealer is telling me it's located under the passenger seat in the front of the vehicle. I've seen the Xantrex Freedom X 1000 inverter there, but I didn't see the MPPT and I'm surprised that it could even fit. When I get the vehicle back from servicing the refrigerator, I'll check.

Check in the rear driver side of the garage. Are you aware of the location of the manual power disconnect knob is located? If you remove the cover, you'll see the wall that houses the buss bars and, fuses and etc. That wall is attached via 2 screws on the right side. When removing the screws, pull the wall towards you and the mppt should be attached on the backside of that wall.

Thanks for the reply. They finally have fixed my refrigerator (replaced a bad control board), and I will get to pick the van up this week! The dealer ended up installing the dongle for me and promised to show me the location, but I believe that you are correct. I'll post a photo once I see it.

on my 2021 Interstate 24GL, the Victron MPPT is behind the overhead bin control panel.
the panel simply pulls out with some force. It's a blue box.

The device under the driver seat is the Batteryminder for the chassis battery, in a 24 GL.

[DavePDX]

So I finally know the location of the MPPT in my 2022 Interstate 19. It's in the garage area on the driver's side in the box containing the red battery switch. Adding the bluetooth dongle was well worth the trouble. I can finally see what's actually happening with my solar. Thanks to everyone who tried to help. Obviously Airstream has a variety of locations they use, so YMMV.

Here are some visuals:

DavePDX, hello, just curious about the Bluetooth dongle. I have a 2021 AI19, same as yours otherwise. When you disconnected the VE cable that sends data to the round MPPT control, did it render that gauge useless? Was the data in the app that much better? I’m considering doing the same…
Thanks,
Adam B

[mike2016]

another option is to replace the MPPT with a newer version that has bluetooth built in.... and sell the old one.

the gauge is pretty useless, i never look at it.

Yes, it disabled the gauge, but that was pretty much completely useless to me anyway. The app is fantastic. Not only can I see in near real time what’s happening with my solar, but I was also able to significantly improve the charging performance by tweaking the settings to Battleborn’s recommendations. This has turned out to be one of the best upgrades I’ve made to the rig. Adding this, along with the Victron SmartShunt has allowed me to mange my power far more effectively.
