Compact 5 A PWM solar charge controller designed to protect and charge 12 V batteries in small solar systems.

• Protects and charges 12 V batteries with a full range of safety protection functions: reverse-current protection (at night), overcharge/discharge protection, overvoltage, overload and short-circuit protection.
• Charging current: 5 A; Load current: 5 A; Rated voltage: 12 V.
• PWM technology increases charge acceptance and prolongs battery life and can recover some lost battery capacity.
• USB interface 5 V DC / 1.2 A for charging mobile devices; bright LED indicators to show battery state of charge, solar panel and load status; load on/off button also available.
• Compatible with sealed, gel and flooded batteries — battery type selectable by the user.
• Use with solar panels up to 60W in total; highest charging efficiency with panels Vmp 17–20 V. For panel voltages over 25 V consider an MPPT controller for maximum efficiency.
• 3 pairs of terminals (solar panel, battery, load) for wire up to 2.5 mm² (approx. 14 AWG); 2 x 4.5 mm mounting holes.
• Self-consumption ≤5 mA; working temperature -35 °C to +55 °C; size 109.7 x 65.5 x 20.8 mm (4.3 x 2.6 x 0.8 in); weight 90 g (3.2 oz).

The product comes with an instruction manual explaining connections and operation. Suitable for small boats, caravans and other compact off-grid setups; ensure panel voltage and battery type are matched for best performance.
