After the multiday power outage experience I'm going to setup my 2008 Prius to be a 1000w generator. Got the Renogy inverter working, placed in the tray above the spare tire. But the questions I have is where in the right rear wheel well / trunk area can I flush mount these panels? They aren't drawn proportional to scale but they are: fuse panel, 12V/USB accessory outlets, and Renogy remote switch. Ideally I want to flush mount it in the right rear wheel well and trunk area, like an outlet in a drywall, so that it's neat and orderly, and not surface mount as the example picture shown below. Is there a spot along this wall that has max clearance between this carpeted trim piece and the actual body metal? I searched and couldn't find any examples of what others have done, so would appreciate any help. Thanks.
You've got a few receptacles there, those need depth. If you want them properly flush to a surface, you'll need to make a new false wall to create the necessary depth. Probably won't have to give up too much cabin width to create it, but to do it without adding a new wall is going to be complicated. You may not need a back wall, but you don't want to wind up with a hot terminal 1/4" away from the outer wall with only a scrap of petroleum-based carpet as padding & insulation. Probably a good idea anyhow so that you can easily access/rewire/remove/hastily extinguish that area in the future. You can borrow a lot from high end autosound installations. Amplifier mount boards & bespoke subwoofer cabinets use the same construction techniques you'll want for your fit & finish goal.
This was a Gen 3, not a Gen 2, so the dimensions and details won't be identical, but I built this thingy on DIN rail that fits entirely under the battery deck board. The RJ-11 telephone cable breakout at the aft end is for the remote control circuit of the inverter, which I ran to a switch on the dash. My very first version of the thingy was for a Gen 1 (which was a sedan, not a hatch), and also used DIN rail, with some creative bending of the rail.
