Photonic Universe 320W 12V dual-battery kit, 20A controller | 4Boats

Photonic Universe 320W 12 V dual-battery solar kit supplied with a 20 A 12 V/24 V dual-battery PWM controller and high-temperature cables — ideal for campers, motorhomes and boats.

• Includes a high-efficiency, waterproof 320W 12 V monocrystalline solar panel perfect for permanent outdoor use to charge 12 V batteries or supply direct power to non-voltage-sensitive loads.
• Panel fitted with 2 x 5 m high-temperature single-core solar cable with male and female MC4 connectors — MC4 connectors can be cut off if connecting to the controller’s screw terminals.
• Solar panel specifications: Peak power 320 W; maximum power voltage (Vmp) 18.35 V; maximum power current (Imp) 17.88 A (Vmp x Imp ~328 W, within ±3% tolerance); open-circuit voltage (Voc) 21.85 V; short-circuit current (Isc) 19.04 A; power tolerance ±3%; dimensions 1956 x 992 x 40 mm; weight ~19.5 kg (~43.0 lb); 8 mounting holes 9 x 14 mm.
• 20 A solar charge controller: 20 A rated charging current; 12 V/24 V automatic selection; designed to manage two batteries (charges and isolates batteries as required to protect starter and auxiliary batteries); PWM technology with 3-stage charging (bulk / absorption / float) to improve charge acceptance and battery life; fully automated protection functions (over-charge, reverse polarity, short circuit, over-temperature etc.); 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 15.5 x 7.6 x 4.0 cm; weight 230 g (~0.51 lb); multiple mounting holes for ease of installation.
• Please note: this is an essentials kit and does not include mounting accessories or batteries; the solar charge controller may be shipped separately due to warehouse arrangements.
• Electrical connection: the solar charge controller is supplied with a detailed user manual and installation instructions — the User manual for DB2024 Photonic Universe 20 A 12 V/24 V automatic solar charge controller is available to download.
• Fitting: the solar panel can be fixed to a flat roof using metal brackets, pole mounts or alternative brackets (mounting hardware not included).

Care & compatibility: keep the panel clean for best output, check cable and terminal connections regularly, and use appropriately sized batteries and fusing. The PWM controller is ideal for standard lead-acid and AGM batteries; seek specialist advice for lithium battery systems.
