40W Solar Kit (2 × 20W) 10A PWM | 4Boats

Photonic Universe 40W solar charging kit with 2 x 20W waterproof panels and a 10 A 12 V/24 V PWM charge controller — ideal for boats, campers and off‑grid use.

• Kit includes two high‑efficiency 20W polycrystalline solar panels (waterproof, rigid aluminium frame).
• 2 x 20W panel specs (per panel): Peak power 20W; Vmp 17.5 V; Imp 1.14 A; Voc 21.6 V; Isc 1.23 A; tolerance ±3%; dimensions 485 x 345 x 25 mm (19.1 x 13.6 x 1.0 in); weight 2.0 kg (4.4 lb); 4 mounting holes; 2 m cable attached.
• 10 A 12 V/24 V PWM solar charge controller designed to protect batteries with automatic cut‑off to prevent over‑charge and deep discharge and to stop reverse current at night.
• Charge controller protections and features: over‑charge/discharge, overload, short circuit and overheating protection; LED indicators; temperature sensor; load on/off button; selectable battery types (sealed/gel/flooded; default sealed).
• Charge controller specs: Self‑consumption 8.4 mA (12 V) / 7.8 mA (24 V); working temperature −35°C to +50°C (−31°F to +122°F); terminals for wire up to 4 mm²; size 138 x 69 x 37 mm (5.4 x 2.7 x 1.5 in); weight 130 g (0.29 lb); multiple mounting holes.
• Remote monitoring: controller can be connected to an optional MT50 remote meter with LCD for monitoring and adjusting the charging process.
• Additional items: 5 m dual‑core battery cable (2.5 mm² cross‑section) included and a user manual with installation instructions.
• Mounting & installation notes: leave ~1.0–1.5 cm (0.4–0.6 in) space beneath panels for cooling; the controller may be shipped separately from panels depending on stock — follow the Installation tab for full steps.

Compatibility: suitable for 12 V or 24 V systems and for sealed, gel and flooded batteries; simple to install — always connect the battery to the controller before connecting the solar panels and follow the supplied manual.
