Moderator+ ScubaRx Posted April 30 Moderator+ Share Posted April 30 I have recently replaced the solar panels on the Outlaw Oliver. I used the old panels to attach to the topper on our truck. The truck panels will be used to keep a new Battle Born 100 Ah charged to run our Dometic CFX3 75DZ refrigerator located in the bed. In reading and researching different aspects of this project, I came across some info concerning the Solar Panel Disconnect Switch that I want to share with the group. All existing Oliver's with a solar system installed at the factory will only have a big red on/off switch installed in the positive side of the power wires coming down into the coach before going to the charge controller. This serves as their Solar Panel Disconnect Switch. The following information is from a guy named Nate Yarbrough and I copied it directly from his Blog Post that is listed below. Is a Disconnect Between the Solar Array and Charge Controller Necessary? Short answer: Yes. And here’s why: NEC 2020 Article 690.13 says that “Means shall be provided to disconnect the PV system from all wiring systems including power systems, energy storage systems, and utilization equipment and its associated premises wiring. Is a Dual Pole Disconnect Necessary for a DIY Camper Solar Array? Again, Yes… And here’s why: NEC 2020 Article 690.13 section (E) States that “ The PV System disconnecting means shall simultaneously disconnect the PV system conductors that are not solidly grounded from all conductors of other wiring systems. Since camper electrical systems are generally NOT grounded, this means that both the positive and negative conductors from the solar array need to be able to be simultaneously disconnected, and our dual pole breaker does exactly that where those other breakers and switches do not. _________________________________________________________________________ This is a link to his YouTube Video. https://www.youtube.com/watch?v=HOXnWXvLXko This is a link to his blog post that gives you all the same info with written instructions, a parts list and pictures. https://www.explorist.life/how-to-wire-a-solar-disconnect-for-a-diy-camper-electrical-system/ 2 Steve, Tali and our dog Rocky plus our beloved Storm, Maggie, Lucy and Reacher (all waiting at the Rainbow Bridge) 2008 Legacy Elite I - Outlaw Oliver, Hull #026 | 2014 Legacy Elite II - Outlaw Oliver, Hull #050 | 2022 Silverado High Country 3500HD SRW Diesel 4x4 Link to comment Share on other sites More sharing options...
