In this video, I’m setting up 10 used 110W solar panels found on Marketplace. After cleaning and testing the individual output, I walk through the wiring configuration required to power my off-grid camper and replace my noisy generator.
Technical Specifications
Panels: 10 used units rated for 110W, 40V, and 3.84A.
Charge Controller: Outback Flexmax 80 with a 150V open-circuit limit.
Battery: 12V 300Ah LiFePO4 (planning to parallel a second for 600Ah total).
Wiring Fix: Corrected a 360V series mistake by rewiring into three banks of three panels (3S3P), bringing the input to ~116V at 6.5A.
Controller Settings: Configured for Lithium with a 14.6V absorption and 13.4V float.
Project Goals
Currently, running the generator costs approximately $3 per day in fuel. By mounting these panels on the Connex, I’m transitioning to a “set-and-forget” solar system to eliminate that expense and enjoy the silence of the Maine woods.
