10A Dual Battery PWM Solar Charge Controller 12/24V | 4Boats

High‑quality 10 A PWM solar charge controller for dual‑battery 12 V/24 V systems, designed to charge and protect two batteries while preventing over‑charge.

• 10 A maximum charge current; compatible with 12 V and 24 V battery systems with automatic voltage detection.
• Maximum solar input power: 160W (12 V) / 320W (24 V); maximum solar input voltage: 30 V (12 V system) / 55 V (24 V system).
• 3 pairs of terminals (solar input, battery 1, battery 2) for independent charging and initial battery‑priority configuration.
• PWM (Pulse Width Modulation) charging to increase charge acceptance and help recover lost battery capacity; selectable battery types (sealed, gel, flooded).
• Protections include reverse current prevention, reverse polarity, short circuit and over‑charge protection; RJ‑45 socket for optional remote LCD meter.
• Self‑consumption: 4 mA at night, 10 mA when charging. Working temperature −35°C (−31°F) to +55°C (131°F).
• Terminals accept wire up to 4.0 mm² (approx. 11 AWG). Size 15.5 x 7.6 x 4.0 cm (6.1 x 3.0 x 1.6 in); weight 185 g (6.5 oz); multiple mounting holes for ease of installation.

Ideal for caravans, campervans and boats; the unit will also operate with a single battery fitted. For installations where the controller is distant from the battery, use the optional remote temperature sensor (3 m) and remote LCD meter (10 m) for best charging performance.
