20 A PWM solar charge controller with LCD for 12–48 V battery systems, offering programmable charging and advanced monitoring.

• Fully automated operation with automatic 12/24/36/48 V detection; rated charging and load current: 20 A.
• Compatible with 12 V, 24 V, 36 V and 48 V battery banks (gel, sealed, flooded); the controller auto-determines the working mode.
• Maximum PV power: 320 W (12 V) / 640 W (24 V) / 960 W (36 V) / 1.2 kW (48 V); PV input voltage up to 96 V.
• Comprehensive protections: reverse polarity, reverse current at night, over-charge, deep discharge, over-temperature, overload and short-circuit protection.
• Interface: LCD display with multilevel menu, LED indicators and 4 multifunction buttons; PWM charging increases battery acceptance and helps recover capacity.
• Real-time monitoring: panel and battery voltage and current, battery state of charge (SOC) and temperature; energy statistics counter for accumulated daily and monthly charge.
• Remote monitoring and programming: supports MT50 remote meter and other remote monitoring/programming methods for expanded control and readout.
• Low self-consumption: max 15 mA (12 V). Working temperature: −25°C to +55°C.
• Terminals accept up to 16 mm² cable. Size: 20 x 10.5 x 6 cm (7.9 x 4.1 x 2.4 in). Weight: 0.7 kg (1.54 lb).
• Installation manual included. Care: install with correct cable sizing, secure terminals and follow the supplied manual for safe operation and optimum battery life.

Note: When sizing systems with a battery bank/inverter, ensure the controller's current rating and cable gauge are adequate for your array and load.
