Waterproof 300W 12V Wind Charge Controller – IP67 | 4Boats

Fully sealed 300 W regulator for 12 V three‑phase wind turbines; IP67 enclosure and automatic braking deliver safe, reliable charging for boats, caravans and remote off‑grid sites.

• Battery voltage: 12 V nominal.
• Compatible turbine power: 100 W – 300 W (3‑phase AC).
• Brake (cut‑off) voltage: 15 V DC; recovery (re‑start) voltage: 13.5 V DC — automatic braking prevents over‑charge and overspeed damage.
• Quiescent current: ≤ 15 mA to preserve battery charge when idle.
• Display mode: LED status indicators for charging, system connection and turbine rpm.
• Operating temperature: -35 °C to +75 °C (-31 °F to 167 °F) for reliable year‑round use.
• Ingress protection: IP67 (submersible to 1 m for 30 min / 3.28 ft).
• Dimensions: 100 x 87 x 28 mm (3.94 x 3.43 x 1.10 in); weight: 300 g (0.66 lb).
• Integrated protection: over‑charge shut‑down with automatic recovery, overspeed/high‑wind dynamic braking, plus short‑circuit and reverse‑polarity safeguards.

Works with any 12 V three‑phase wind turbine from 100–300 W. Supplied as model FW03-12 with an illustrated user manual and a 12‑month warranty — ideal for marine, caravan and remote off‑grid installations.
