Your Xantrex inverter install looks stunning! Nice job!
Thanks so much, I wasn't sure how that copper colored Aluminum sheeting would look, but it was on Clearance at HD and virtually free so I went with it. It does look much nicer than an exterior Inverter bay needs to look, and I am pleased with how it's turning out.

I forgot to mention that I used 1" aluminum angle stock to make the mounting bracket for the separation wall between the inverter bay and the rest of the compartment. I just screwed the angle stock pieces into the compartment to make a frame. So then at the very end of my installation, I'll just screw a piece of the copper colored Aluminum sheeting to that frame.

Will your remote or app allow you to reboot? You may not need the physical button.
I don't know right now, but will learn all about how to use the remote controls and the App. But regardless, I tried to think ahead to be able to access that small circuit breaker reset button if I need to in the future.

Actually, I looked this us as I'll never be able to get to mine. Here is what it says about the reset button between the two fans:

"A supplementary protector with reset button provides overload protection for the Freedom XC PROGFCI Kit (PN: 808-9817) (sold separately) option. Press to recover from an overload condition. In a hard wired installation, the supplementary protector does not protect output wiring."

So I'm thinking if you are using the AC output option of the inverter and not the optional GFCI, you will never need to press this button.

Here is a simple video, showing why switching out your Leisure GoPower PWM controller for a MPPT Controller gets you up to 30% more power from your solar panels and offers a higher quality battery charging capability. A MPPT charge controller and glass monocrystalline panels are a must, in my opinion, for the highest quality and most efficient solar system. I selected the Victron Smart Controller 100v/30a, https://www.amazon.com/SmartSolar-M...9Y2xpY2tSZWRpcmVjdCZkb05vdExvZ0NsaWNrPXRydWU=, for my 400w glass solar panel installation. Changing out the GoPower is a very straightforward replacement. I previously posted a lot of information on that in this post, https://m.facebook.com/story/graphq...wMDAwMDMzNTI5NzY4NDpWSzo0OTU0NjgzNjcxMjcyMDI5. If you are interested in expanding to more than 400w then by a 100v/50a sized MPPT solar charge controller.

Many have been asking me for the easiest method to replace their GoPower so here is what I came up with. The easiest method would be to just install a switch and corresponding connectors, https://www.amazon.com/gp/product/B08623N19Z/ref=ox_sc_act_title_4?smid=AXDXPO2RICYQJ&psc=1 and https://www.amazon.com/gp/product/B07MPMJRY1/ref=ox_sc_act_title_2?smid=A205VE1PUGXUMQ&psc=1, on the positive wire from the Solar panels just before the new solar controller using this switch and screw terminal connectors. Just use a lighter to add a little heat to make the heat shrink smaller or just wrap with black electrical tape to cover the metal body of the connector. Take the positive solar wire and cut it 6" or so back, correct length between switch and controller. Then add a connector to two ends so you can wire the switch in just before the controller and wire the new controller in place. Just mount the Victron controller to the back of a cover panel (made from a thin sheet of plastic or wood) and install the switch on the front side. Since the Victron is Bluetooth it doesn't need it to be visible. Screw the new cover panel, using existing GoPower controller mounting screws/holes. I hope this makes it easier to add a switch and new Victron controller.

Great job and thank you for taking the time to document it. I'm going to tackle the inverter install next weekend.

Did you find any easy way to get the partition between the inverter and the storage bay out?

Are the terminal posts on the Lithtronics batteries 5/16?

I've never used VHB tape, there are so many different kinds I'm not sure which 3M number to use. Of course I'm looking for high bond strength but also something that will hold up to the desert heat when it gets into the 120's. What would you suggest?

I didn't have an inverter bay, so maybe someone else will chime in with tips to remove the wall. DiverBob may have explained how he did it in his electrical upgrade thread. Search for it. The Lithionics battery bolt is metric M8-1.25. See lost #89, https://sprinter-source.com/forums/index.php?threads/93929/page-5. I believe 3M 5952 VHB tape is the best for adhesion and high temperatures. Here is a chart I posted before when someone questioned choice of 5952 over 4950. I just finished my inverter installation and am posting about it here in #109, https://sprinter-source.com/forums/index.php?threads/93929/page-6. Good luck on you inverter installation.
