Where are the busbars on a 27FB Queen?

[AirMiles]

I can’t believe I have to ask this question! I searched the forum and could not find the answer. I asked the service tech and manager at a five-rivet Airstream dealer and they did not know. I pulled the protective panel in front of the inverter off and found the solar prewire. The solar prewire goes into a compartment between the front storage bin and the curbside nightstand. I believe the busbars may be inside that compartment. I haven’t found any way to access that compartment. I would appreciate help with locating these busbars from someone who’s actually gotten their hands on them in the past. I can’t believe how well hidden these busbars are on a 27’ queen.

And now for those who have been participating in my Solar Show and Tell thread, I just purchased a new 27FB queen Globetrotter! I now have the opportunity to install 600W of series-parallel solar on the factory prewire. Stay tuned to the Solar Show and Tell thread for documentation on how 600W on the prewire performs. Based on my experience with 400W on the prewire, I expect great performance from 600W.

The last one I installed solar on, the 12v bus was curbside, accessed from the front storage compartment. It was a twin, and I could have accessed it by removing the base for the bed on that side, as well.

My next attempt will be to remove the plywood from the bed base to get better access to the front storage area. Maybe that will uncover the access point to that compartment.

Thanks for sharing your knowledge. I expect the busbars to be in the front curbside area. There’s a grey pvc box inside the storage bin labeled 12V or electrical. Could they be inside that grey PVC box?

The grey PVC box on my 25FBQ is for the 7-way connections only.

I found them! They are inside that grey PVC box on a Globetrotter 27FB Queen. Attached is the picture to document this.

Yes, but the box on my FB25 also said something similar and, as you said, the busbars are outside of that box. Taking the plywood off the bed gives much better access than reaching around the trailer tongue and propane tanks. Once I got the plywood off, it was obvious that the other compartment I considered was not accessible and therefore they had to be inside the grey PVC box.

Good deduction. I had to take the plywood off my bed to do my electrical upgrade a few years ago. Pretty good access after you clear the stuff out, but it was a chore.

Also removed the plywood, emptied the front compartment and could sit inside and work on the wiring. Looks like AS has clocked the box 90º on your 2017.They left a few mounting screws out on mine and the solar controller mounting screws were half installed so the controller could move around. I was installing a Victron BMV-712 shunt.
