20A PWM Solar Charge Controller 12/24V LCD | 4Boats

20 A PWM solar charge controller for 12 V or 24 V battery systems with an LCD display, adjustable charging settings, MT50 support and energy statistics. Suitable for RV, boat, cabin and small off-grid systems.

• Rated charging and load current: 20 A. Fully automated operation with auto 12 V/24 V selection.
• Maximum PV input: max PV open-circuit voltage (Voc) 48 V; supports solar panel power up to 320 W (for 12 V systems) or 640 W (for 24 V systems).
• Charging technology: PWM (Pulse Width Modulation) to improve charge acceptance and extend battery life.
• Display & interface: LCD display with multi-level menu and four multifunction buttons for configuration and monitoring.
• Monitoring & statistics: real-time voltage, current, state of charge (SOC) and temperature monitoring, plus accumulated daily and monthly charge/energy counters.
• Load output modes: manual, light (sensor) and timer (programmable) for lighting and load control.
• Remote & PC connectivity: supports MT50 remote meter and computer connection via communication port for expanded monitoring and configuration.
• Protections & consumption: built-in reverse polarity protection, over-current/short-circuit protection and over-temperature protection; self-consumption ≤44 mA (max).
• Operating conditions & mechanical: operating temperature -20 °C to +55 °C; size 16.5 x 10 x 5.0 cm; weight 500 g.
• Installation & documentation: simple wiring, fully automated operation and includes a detailed user manual that explains wiring, load modes and battery type programming.
• Battery compatibility: suitable for a single battery bank using gel, sealed (AGM) or flooded lead-acid batteries.

Designed for small to medium off-grid systems such as RVs, boats and cabins; refer to the manual for wiring diagrams and battery type programming.
