45 A PWM solar charge controller with an LCD display and advanced programmable settings for 12 V and 24 V battery systems.

• PWM technology to increase charge acceptance and extend battery life; full electronic protection (reverse current at night, over-charge and deep-discharge cut-off, over-heating, over-load, short circuit and reverse polarity protection).
• Compatibility: works with solar arrays up to 640 W (12 V) / 1.28 kW (24 V); wide solar input voltage up to 48 V — most efficient when panel Vmp is marginally above battery voltage (e.g. 17–18 V panels for 12 V batteries).
• LCD display with multilevel menu operation and a user-friendly interface with 4 multifunction buttons; LED indicators and built-in temperature sensor; real-time monitoring including voltage, current, battery state of charge and temperature; energy statistics counter for daily and monthly accumulated charge.
• Access to charge controller data via the MT50 remote meter for extended monitoring and control.
• Controller specifications: rated current 45 A; fully automated operation with auto 12/24 V selection; enhanced monitoring and programmable charging parameters and load work modes.
• Self-consumption: max. 15 mA. Working temperature: -25 °C to +55 °C. Terminals accept wire up to 35 mm². Size: 20 x 11 x 6 cm (7.9 x 4.3 x 2.4 in). Weight: 800 g (1.76 lb).
• Installation: this unit comes with a detailed user manual which explains wiring, programming and safe operation.

Designed for single batteries or battery banks (gel, sealed or flooded). The controller auto-detects 12 V or 24 V systems and is suitable for small to medium solar charging installations.
