Is it possible to get a wire diagram of your travel trailer from Grand Deaign? Also, someone posted a link with the GD letter head with instructions on how to utilize the inverter prep that was done at the factory. Where did that come from? I need docs like that, especially one on my 30 amp charge controller prep. I just bought a 2025 Transcend XPLOR25MLX and I want to install a 3000 watt inverter with 2 200Ah batteries and eventually add 3 200 watt solar panels to go along with a 30 amp charge controller. Thank you for your help.

While there may be diagrams for the production line when a rig is built, those diagrams are (most of the time) not actually followed. Each rig is unique unto itself, depending on who actually did the set up on the production line. The only way to get a diagram for YOUR rig would be to trace out the wiring yourself (as some of us have).

I don't believe any prep is rated for 3000 watt, may as well plan on a full install...Xplor is up to 2000 watt.

Grand Design will provide info at this level. Not entirely useful, but does give you some indicators on your searching for issues.

I would pull the breaker panel out enough so you can see if there is a "split busbar". The shorter side of the busbar is usually the side that the inverter powers up if its pre-wired that way. I suppose if you wanted to power up the whole rig for boondocking a 3000 watt inverter-charger would be the way to go. But if you just want to power the inverter ready part of the breaker panel then a 2000 watt inverter rated at 20 amps could work fine. Either way I would get one with a built-in automatic transfer switch. Use 4/0 size battery cables with a 3000 watt inverter or 2/0 battery cables with a 2000 watt inverter.

I asked Grand Design for a wire diagram for our 2025 22RK Reflection and they said "unfortunately we do not have wire diagrams available that I can send to you. I could send an electrical layout, but not a print showing each wire".
