100W 18V Solar Panel Kit with Charge Controller, Dual USB, for RVs, Boats, Camping, 42x28 cm

100W 18V Portable Solar Panel Kit A compact, ‑output solar solution designed for mobile power needs. The panel measures 42 cm by 28 cm, making it easy to mount on a roof, deck, or backpack frame. A built‑in charge controller regulates voltage and protects connected devices, while dual USB ports allow simultaneous charging of phones, tablets, GPS units, or small lights. Key Benefits Reliable 100‑watt output provides sufficient power for small appliances, battery maintenance, and emergency electronics. Fixed 18‑volt voltage matches common 12‑volt and 24‑volt battery systems used in recreational vehicles, boats, and portable power banks. Dual USB ports deliver up to 5 V 2.4 A per port, enabling fast charging of two devices at the same time. Integrated charge controller prevents over‑charging, over‑discharging and short circuits, extending the life of both the solar panel and the storage battery. Compact size and lightweight construction simplify installation on limited surface areas such as RV roofs, boat decks, or backpack frames. Weather‑resistant frame and tempered glass protect the cells from rain, dust and mild impact, ensuring consistent performance in outdoor conditions. Product Features Power rating: 100 W peak, 18 V nominal Dimensions: 42 cm (length) x 28 cm (width) Output connectors: 2 USB‑A ports, each 5 V 2.4 A, plus MC4 connectors for direct solar array connection Charge controller type: PWM with LED status indicators for charging, fully charged, and fault conditions Materials: anodized aluminum frame, tempered glass front layer, ‑efficiency monocrystalline cells Compatibility: standard 12 V and 24 V lead‑acid or lithium battery banks, RV and marine power systems, portable power stations Typical Use Scenarios 1. Road trips with an RV – Mount the panel on the roof to keep the vehicle's auxiliary battery topped up while traveling, eliminating the need for propane generators or frequent plug‑in charging. 2. Boating and marine use – Install the panel on a cabin roof or deck to maintain battery health during overnight stays at anchor, ensuring navigation lights, radios and pumps remain operational. 3. Camping or emergency preparedness – Deploy the panel on a backpack or portable stand to charge phones, LED lanterns and small radios during extended stays without grid access, providing a reliable power source in off‑grid situations. Installation and Operation Position the panel where it receives maximum sunlight, preferably facing true south (in the northern hemisphere) or north (in the southern hemisphere). Secure the panel with the supplied mounting brackets or straps; no permanent modifications are required. Connect the MC4 cables to the charge controller, then link the controller to the battery or power station. Plug devices into the USB ports for immediate charging, monitoring the LED indicators for system status. Maintenance Keep the glass surface clean with a soft, damp cloth; avoid abrasive cleaners. Inspect the mounting hardware periodically for tightness and corrosion, especially after exposure to salty or humid environments. This 100 W 18 V solar panel kit provides a practical, dependable source of renewable energy for mobile and off‑grid applications, delivering consistent power while protecting the connected battery and devices.
