【BIG POWER, STILL PORTABLE】 Folds to 19.3×37.4×1.1in and weighs only 15.2lb, so this 300W panel packs serious energy yet remains slim and easy to move, mount, or store for RVs, vans, boats, and backup use.
【SEPARATE CONTROLLER FOR SAFER CHARGING】 Equipped with a standalone PWM controller that protects your 12V system from reverse polarity, overcharge, overload, and short-circuit—and can be replaced or upgraded later if needed.
【LONG REACH FOR FLEXIBLE SETUP】 Includes a 9.85ft (3m) cable, allowing you to place the panel in full sunlight while keeping the controller or power station safely shaded for cooler, safer operation.
【KNOW YOUR POWER STATION’S LIMITS】 Some power stations restrict solar input (often 100-200W). Even under full sun, a 300W panel cannot exceed your unit’s own cap—this is normal design, not a defect. Please check your model or message us for confirmation before ordering.
【USB CHARGING WHEN YOU NEED IT】 When connected to a 12V battery, the dual USB ports provide stable power for phones, lights, and small devices. Even without a battery, they can still work in sunlight for emergency top-ups, though current may fluctuate.
【MONOCRYSTALLINE EFFICIENCY, BUILT FOR OUTDOORS】 High-grade mono cells deliver better conversion efficiency and reduce mismatch loss. The panel surface is weather-resistant, but avoid leaving the fabric case in heavy rain or strong sun for days to extend life.
【COMPLETE BUNDLE READY TO GO】 Includes the 300W foldable panel, separate controller, SAE/XT60/Alligator clips, DC5521/5525/35135/6440 adapters, 9.85ft cable, storage bag, and manual—a one-stop kit for camping, RVing, or emergency backup.
