I also had less trouble getting the wires out of the refrigerator compartment than I feared. There were two layers of plywood with about an inch of styrofoam in between but enough space behind the water tank to move the wires. I pulled them out with a back scratcher. I could not find a wire hanger!

I stuffed stainless steel wool around the wires and sealed with foam.

I finished bolting the panel racks today.
[image]
I could tell I hit something solid behind the trim. I used double sided Eternabond behind the holes to waterproof. The photo shows the adjustable furniture legs I’m using to make the racks sturdier.
[image]
I plan to bolt the legs onto the racks.
I ended up just cutting the refrigerator vent panel off at the rear. What is left still covers the vent fully.
[image]
I also further configured the Cerbo GX to read data through the mifi. When I did it earlier I didn’t reboot and the change was lost.
This was the morning after running the equipment and the fantastic fan overnight.

The AC info will never populate unless I replaced my generator and charger with Victron products.
Today was the best solar generation although if was a bit cloudy.

The graph from the Cerbo can tell when I plugged in the RV and ran the charger even though I don’t get that info on the display.

It’s a cool tool but has limited usefulness for the cost.

I would cut smaller chunks of the angle you used and put it on the short side of the panels also. it will stiffen up your total brackets and also let you put a mount on each end of the panel which will prevent flexing while your driving.

I was faced with a similar thought/feeling/fear regarding the lack of thickness on my RV roof when drilling/screwing down solar panels. It seemed really thin.

Here's a link to what I did and how my install went:
https://www.rv.net/forum/index.cfm/fuseaction/thread/tid/30217540.cfm

Summary: Instead of 4 brackets per panel, I ended up with 8. I also used 3M double sided tape in between the bracket and the roof to give them extra grip/holding power. They seem 100% unmovable still one year later.

If you are like me, you probably had a little fun coming up with your solution. I applaud your ingenuity. The adjustable furniture feet to give your panels extra support across the span are crucial. You might consider using 3M double sided tape to hold them down to your roof so the panels don't bounce while driving down the road.

Enjoy your sunshine power!

I just doubled my rooftop solar with a panel from amsolar.com. I really, really like their mounting system. (But, I don't trust their recommendation that the double stick tape is enough to hold the panel to the roof. I also used 2 screws per foot.) If I ever mount a panel I buy somewhere else, I will still buy their mounts.

YES!
I had read and even commented on your post while I was planning for solar. It was very helpful. Thanks.
I finally finished my mounting system and wiring and camped last weekend in a very quiet campground. We were not the only ones not using a generator! It was sweet to use the inverter for morning coffee and toast bread for lunch sandwiches. I experimented running the refrigerator on the inverter before we left and I only got 8 hours overnight so we used gas for that. At most we used about 25% of our 200 amps overnight before the sun was charging them again.

I mounted the panels behind the air conditioner bonnet. I didn’t really have enough room further forward. We backed into a north-south facing site. The trees didn’t shade the panels. I’m thrilled that they work so well.

Great resource thanks. I looked at the mounts. They look similar to the mounts I used. I didn’t understand the rocking mounts.
One thing I was happy about is that the roof racks did not make noise as we drive.
I do have a roll of the 3m tape. I thought I would use it under the furniture legs but I have not yet. I was concerned about the screws in the roof though I know many people use the tape and screws. I like that the holes are at the side rails. I think they will be easier to remove when the time comes.

I have an Airstream. Airstream trailers don't have flat roofs. The roofs are curved. The rocking mounts don't actually rock. But you can pivot them so they sit flat on the roof surface, no matter what angle that surface is. Once attached to the roof, the mount is as rigid as any other mount.

Thanks that’s very cool. I have a niece with an Airstream. I’ll let her know. Thanks.
