Solar charge controllers

---

– add cables and an MPPT solar controller

---

Items to connect the panels and controller to the battery:

Note: Connecting directly to the battery is better than using the trailer’s side solar port.

SAE connector method

MC4 connector method

If installing the solar controller inside the trailer, check out the Battery/Solar Wiring Parts page.

12V roof solar panels

– If adding another solar panel/s to an existing roof solar setup, you don’t need to buy a solar controller since the trailer should already have one inside on a wall.
– Don’t bother with 100 watt panels on the trailer roof. Labor is the largest cost.
– If your trailer already has a factory solar panel, it is most likely 12V. Purchase another 12V panel (matching the wattage as close as possible) and a parallel splitter/adapter. Most are 175-200 watt from the factory.

Roof panel accessories

Note: If there isn’t an inline fuse, you’ll want to put a circuit breaker on the positive cable between the solar panel and solar controller.
