Everything i’ve read says the flex panels won’t last & I only want to do this install once
It’ll take a bit more installation time for the solid panel mounts, but it’s the most reliable result

I have a 2018 27.2 ACE. I found the solar wires from the roof in the electrical area under the bed (orange/yellow.). I also installed a 1500 W PSW inverter in the storage cabinet adjacent to the batteries, and ran the output into this cabinet from below. I then hardwired it, with an A/B switch, to two circuits that control plugs and TV’s. (Cut the Romex after the circuit breakers,before the plugs etc.). I’d like to use the cables that are in there from the charger/converter to hook up the solar, after they run thru a solar controller. Looking for help on how to do that.

Yes I know that I am Solar ready. We have installed a panel and are very happy with having it in our system.

Mine is attached to the roof of a storage compartment on the drivers side just past the generator.

Ok
My parts came in, everything looks clean (I ordered everything from Amazon, & saved $$$ via the open/damaged box warehouse)
So, with connectors & 30amp controller...$310 + sales tax (on some, but not all items).

I’ll mount the two solid panels on the roof with the drill-free mounts
On-line, it is suggested that I “rough-up” the drill-free mount underside with a Dremel where the Sikaflex adheres to the roof.

I’ll wire the two panels in parallel, with branch connectors, and run the +/- lines down the refrigerator vent using 10 gauge stranded wire (20’ @ $.35/ft x 2) directly to the PWM 30amp controller located just inside at the entry door wall

Then a short run from the controller to the +/- battery terminals under the steps

Photos to be added shortly...

I can't speak to how you're wiring your inverter. With my solar, I installed the solar prewire (orange) to a 30 amp breaker to the solar controller. The output is wired to another 30 breaker and then with #8 wire to the "live" side of the latching relay (charging solenoid). The grounds connect through to the coach ground block nearby. Use ring crimp connectors to make it simple. While you're in there, it would be smart to move the latching relay off the floor (WTH?) up higher where you can easily reach when it needs to be replaced. Think it thru, take your time and label everything.

UPDate on my solar install...
I pre-wired #10 wire from the roof, down the cool side (rear) of the refrigerator vent, then down under the fridge, across the floor under the sink to the entry wall.

I also pre-wired a 2nd set of wires from the controller to the batteries. A 30 amp fuse is between the controller and the positive battery connection.

So right now I’ve got my controller connected to the battery box and I get my standard readings without solar charging.

And later this week, time permitting, I’ll Sikaflex the drill-less plastic mounts, screw in the two 100 watt panels, and make the final connections.

An you tell me where the converter is located (I have a 2018 24.1 and want to add some solar)

“Converter” is located below the Fridge, has all the breakers and fuses (if that’s what you’re asking)

2018’s did not include a “Solar Controller”.
2018’s are “pre-wired” from the roof to the area under the refrigerator.
Remove the panel next to the “Converter” (below the Fridge), and look for the wires.

Personally, I have not seen photos of what the bare wires look like.

Let us know what you find.

Are you confident of those mounts? It seems that with the air that will be rushing underneath the panels, the mounts better be rock solid.

Well...
They were installed 9 months & 6,000 miles ago.
When last checked they were rock solid.

That said, you can always plant a single screw in each foot if it makes you feel better.
But the point of the mounts is to eliminate any punctures in the roof.

Many on this Forum have screwed mounting plates into the roof and are fine with it.
Others have used flexible solar panels with Eternabond tape.

So, there are other options for you.

Looks like the panels likely don't catch much air with those mounting locations aft of the rig and behind the a/c and skylight as well as being aft on the rig.
My rig is pre-wired solar and the hard connection is just forward of the aft fan cover. I'm contemplating my approach to this. A correctly positioned panel with screwless mounts appears to have some merit.
