Complete 30W Solar Panel Kit for 12V Battery Systems What this kit provides Complete kit ready to install: 30W polysilicon solar panel, 30A solar charger voltage regulator controller (supports 12V and 24V systems), cigarette lighter harness for battery charging, battery clip harness, four suction cups for temporary mounting, and user manual. Compact panel size: approximately 435 x 200 x 2 mm for easy placement on vehicles, small roofs, or flat surfaces. Durable construction: polycrystalline polysilicon solar cells with PET backing for good light transmission and sealing; controller housing made of ABS. Key benefits and why you need it Reliable battery protection: the 30A controller prevents overcharge, overvoltage, overdischarge, short circuit, and reverse connection to help extend battery life and reduce maintenance. Simple setup and flexible connections: included cigarette lighter line and battery clips let you connect to vehicle, boat, or standalone batteries without extra wiring. Suction cups and compact size make temporary mounting quick and convenient. Maintains common 12V battery types: designed to charge and maintain AGM, Flooded, GEL, and Deep Cycle batteries used in cars, RVs, boats, cabins, gates, and trailers. Versatile for offgrid and backup use: suitable for remote power needs, trickle charging, and maintaining batteries during storage or intermittent use. Performance and compatibility Power: 30W solar panel output. Controller: 30A solar charger voltage regulator, compatible with 12V and 24V systems; protects against common electrical faults. Battery focus: optimized for charging and maintaining 12V battery systems and compatible with AGM, Flooded, GEL, and Deep Cycle batteries. Materials and size: polysilicon solar cells with PET backing for improved light absorption and sealing; controller made of ABS; panel size approx 435 x 200 x 2 mm. Typical use scenarios RV or camper maintenance: keep the house battery topped up during storage or while dry camping to preserve battery charge for lights, pumps, and electronics. Remote gate or pump power: power or maintain batteries for gate openers, garden pumps, and offgrid equipment where mains power is not available. Boat and trailer battery upkeep: provide trickle charging to marine batteries while docked or during periods of inactivity to prevent deep discharge. What is included 1 x 30W Solar Panel 1 x 30A Controller (12V 24V) 1 x Cigarette Lighter Line 1 x Battery Clip Line 4 x Suction Cup 2 x Manual Practical notes This kit is intended for 12V battery systems. The controller supports both 12V and 24V system voltages; for most uses in this kit, connect to a 12V battery. Ensure correct connection polarity when attaching clips or leads to avoid triggering reverse connection protection. For permanent mounting, consider using suitable fasteners in addition to the included suction cups.
