Lithium, Inverter, and Solar Upgrade

[Grizz000]

Hi everyone — I previously did an intro in the introductions section, but my wife and I are new (to us) Oliver owners (about 2 months in). We’ve camped twice so far and already have several trips planned over the next several months, including a lot of boondocking in USFS campgrounds. I've had travel trailers of various forms for about 20 years and we are super excited to now be Oliver owners.

I just finished a lithium / inverter / portable solar upgrade on our 2019 Legacy Elite II (Hull 514) and put together a detailed project write-up with photos, wiring approach, parts list, and lessons learned (see attached). The trailer came from the factory without an inverter, no roof solar, and no solar connector. It had two AGM batteries when we bought it. The main goal was a clean, reliable, serviceable install that leverages the existing factory AC/DC wiring/routing and keeps the system simple (including an inline inverter/charger pass-through so the trailer’s AC panel works “like stock,” just with inverter capability).  

I found great info on this forum as I undertook this project and hope to give back just a little by posting this as a practical reference for anyone planning a similar upgrade — happy to answer questions or share any additional photos/details if it helps.

Happy camping!!
