300W Travel Trailer Solar Kit — 3×100W Monocrystalline with 40A MPPT
A compact, travel-ready solar kit that delivers 300W of clean power for RVs, boats, and trailers. It combines three high-efficiency 100W monocrystalline panels with a 40A MPPT charge controller and all necessary cables and mounts to get you off-grid more quietly and reliably.
Benefits
- Reduce or eliminate generator use so outings are quieter and more relaxing.
- Keep batteries topped off for lights, appliances, and electronics without constant shore power.
- Spend more time off-grid—solar provides steady daytime charging while you travel or camp.
- Everything included means faster setup and fewer trips to the hardware store.
- Compatibility with 12V lithium batteries makes system upgrades simple and efficient.
Features
- Three 100W monocrystalline panels with 9 busbars for improved cell performance.
- 40A MPPT charge controller for efficient solar-to-battery conversion and better charging under variable conditions.
- Included DC cabling: solar-to-controller and controller-to-battery cables sized for travel installations.
- Mounting Z brackets for easy rooftop attachment on trailers and RVs.
- Inline fuse protection between controller and battery for added safety.
- Designed for 12V systems and compatible with 12V lithium battery banks (recommended pairing: 200Ah 12V Lithium).
