SOLPERK 50W 12V Solar Panel Kit — Waterproof Trickle Charger with 10A Controller for Boat RV Car Motorcycle

SOLPERK's 50W 12V solar panel kit is a compact, weatherproof trickle charger that maintains and gently tops up 12V batteries for boats, RVs, cars, motorcycles and off-grid equipment.

This kit pairs a high-efficiency monocrystalline 50W panel with an IP65 waterproof 10A controller to provide reliable, low-maintenance battery maintenance. Built with low-iron tempered glass and an anodized aluminum frame, the panel resists corrosion and extreme weather while delivering steady power to LiFePO4, lithium-ion, AGM, SLA, GEL and other 12V battery types. The plug-and-play cabling and pre-drilled mounting points make installation straightforward whether mounted on a roof, deck, or vehicle surface.

How does this kit keep my 12V battery healthy?

The included smart 10A controller uses a three-stage charging algorithm that prevents overcharge and restores batteries to stable float voltage. It monitors charge status with LED indicators so you can quickly see when the battery is charging, full, or in float mode. Because it is designed for trickle and maintenance charging, it avoids the stress of constant high-current charging.

• Three-stage charge (bulk, absorption, float) to reduce battery degradation
• Compatible with multiple 12V chemistries including LiFePO4 and AGM
• LED status indicators for clear charging feedback

How durable is the panel for outdoor and marine use?

The panel features low-iron tempered glass and a corrosion-resistant aluminum frame engineered for long service life in outdoor environments. It’s rated to handle strong winds and significant snow loads, and is fully waterproof to withstand rain, splashes, and marine exposure. Combined with sealed cable connections and waterproof controller housing, it’s built for rugged, all-season use.

• Tempered low-iron glass for improved light transmission and impact resistance
• Aluminum frame resists rust and corrosion in coastal or wet conditions
• Weather ratings that support high wind and snow loads for reliability

Is installation and everyday use straightforward?

Yes — the panel arrives with pre-drilled mounting holes and essential fasteners to speed up roof or wall installation. Cable ends are plug-and-play with SAE connectors and alligator clips included for temporary or permanent connections. The controller is intuitive with simple wiring and visible LEDs, so routine use and monitoring are easy for non-technical users.

• Pre-drilled holes and mounting hardware for quick attachment
• SAE extension cable and alligator clips for flexible connection options
• Plug-and-play cabling reduces setup time and wiring errors

What components and support come with the kit?

The package contains the 50W solar panel, an IP65-rated 10A charge controller, connection accessories, and multiple mounting pieces. SOLPERK backs the kit with after-sale support and technical help, plus a one-year after-sale period for customer service inquiries. Spare mounting pieces and easy-to-follow wiring minimize downtime and simplify replacements or adjustments.

• 1 × 50W monocrystalline solar panel and 1 × 10A waterproof controller
• SAE extension cable, alligator clips, and four sets of mounting hardware
• One-year after-sale support and lifetime technical assistance
