120W 12V Dual-Battery Solar Kit | 4Boats

Compact essentials kit with a waterproof 120W 12 V monocrystalline solar panel, a 10 A dual-battery PWM controller (12/24 V) and high-temperature solar cables — ideal for campers, motorhomes, boats and yachts.

• Solar panel: high-efficiency, waterproof 120W 12 V monocrystalline panel suitable for permanent outdoor use on campers, motorhomes, boats, yachts, sheds and remote sites.
• Cable and connectors: fitted with 2 x 5 m of special solar cable that tolerates high roof temperatures and reduces power loss; pair of male/female MC4 connectors fitted (can be cut off when wiring to screw terminals).
• Solar panel specifications: Peak power: 120W; Maximum power voltage: 20.2 V; Maximum power current: 5.94 A; Open circuit voltage: 23.9 V; Short circuit current: 6.31 A; Power allowance range: ±3%; Dimensions: 1180 x 540 x 30 mm (46.46 x 21.26 x 1.18 in); Weight: 8.3 kg (18.3 lb); 4 mounting holes 9 x 14 mm; includes 2 x 5 m of high-quality single-core solar cable.
• 10 A solar charge controller: kit includes a 10 A 12 V/24 V dual-battery solar charge controller designed to charge and protect two batteries independently with automatic cut-off to prevent overcharging. Uses PWM technology to increase charge acceptance and prolong battery life.
• Charge controller specifications: fully automated operation with auto 12/24 V selection; 3 pairs of terminals (input, battery, load); protections including over-charge, over-discharge, short-circuit and reverse polarity; self-consumption 4 mA at night, 10 mA when charging; working temperature -35°C to +55°C (-31°F to +131°F); terminals for wire up to 4.0 mm²; size 155 x 76 x 40 mm (15.5 x 7.6 x 4.0 cm); weight 185 g (0.41 lb); multiple mounting holes for ease of installation.
• Dual-battery operation: set initial charging priority between two batteries (for example 80% engine / 20% leisure). When one battery is fully charged the controller reallocates charge automatically.
• Battery compatibility: suitable for common battery chemistries including AGM, GEL and flooded (FLA). For LiFePO4 and other chemistries, check battery manufacturer requirements and confirm compatibility with a PWM controller.
• Installation and shipping notes: due to warehouse arrangements the solar charge controller may be shipped separately. The included controller is supplied with a detailed user manual — see the Installation tab for guidance.
• Please note: this is an essentials kit and does not include mounting accessories or batteries. The panel can be fitted to a flat roof using metal brackets; MC4 connectors can be cut off when wiring to a controller's screw terminals.
• Care and compatibility: waterproof panel and robust frame suit all-weather marine and road use; ideal for powering lights, leisure equipment, pumps or motors where input variation is acceptable. Check battery capacity and system wiring before installation. For warranty details, refer to the product documentation supplied with this kit.
