Photonic Universe 180W 12V Dual Battery Solar Kit 20A PWM Controller

180W 12 V dual-battery solar kit with 20 A PWM charge controller and cables — ideal for campervans, motorhomes and boats.

• With controller and cables — 180W solar panel: this high-efficiency, waterproof 180W 12 V monocrystalline solar panel is perfect for permanent outdoor use to charge 12 V batteries.
• Solar panel electrical specs: Peak power 180W; maximum power voltage 20.2 V; maximum power current 8.91 A; open-circuit voltage 23.9 V; short-circuit current 9.47 A; power allowance ±3%.
• Panel mechanical specs: Dimensions: 147 cm (57.9 in); weight: 11.5 kg (25.4 lb); 8 mounting holes 9 x 11 mm (0.35 x 0.43 in).
• Cabling and connectors: supplied with 2 x 5 m (16.4 ft) high-quality single-core solar cables with MC4 connectors suitable for high roof temperatures; MC4 connectors can be cut off when wiring to screw terminals of the charge controller.
• 20 A solar charge controller: rated charging current 20 A; fully automated operation with auto 12/24 V selection; dual-battery independent charging; PWM technology to improve charge acceptance and battery life; 3-stage PWM charging (bulk/absorption/float) to optimise battery conditioning.
• Controller protection features: built-in protections including overload protection, short-circuit protection, reverse polarity protection and reverse current protection to safeguard panels and batteries.
• Charge controller details: self-consumption 4 mA at night, 10 mA when charging; working temperature −35°C to +55°C (−31°F to +131°F); terminals accept wire up to 4.0 mm² (≈ AWG 12); size 15.5 x 7.6 x 4.0 cm (6.10 x 2.99 x 1.57 in); weight 230 g (0.51 lb); multiple mounting holes for ease of installation.
• Installation and supply notes: electrical connection — the solar charge controller is supplied with detailed use and installation instructions; the solar panel can be fitted to a flat roof using metal brackets; due to warehouse arrangements the charge controller may be shipped separately. Please note this is an essentials kit and does not include mounting accessories or batteries.
• Suitable uses and limitations: ideal for campervans, motorhomes, boats, sheds, farms, remote telecoms/monitoring or direct powering of non-sensitive loads; not suitable as a complete mounting or battery solution on its own. Compatible with standard 12 V lead-acid battery types (flooded/AGM/GEL); consult your battery manufacturer or installer for settings for Li-based batteries.

Care: keep the panel clean and free of heavy shading; follow the supplied installation guide and respect battery manufacturer recommendations for safe charging and compatibility with 12 V systems.
