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

20 A PWM solar charge controller for 12 V/24 V systems with an LCD display, designed and made in Italy for motorhomes, boats and off‑grid lighting. PWM charging improves charge acceptance and can recover some lost battery capacity. The controller is supplied with a detailed instruction manual and a 5‑year manufacturer warranty.

• Rated charging and load current: 20 A; fully automated operation with automatic 12 V / 24 V selection.
• Maximum solar panel input voltage: 55 V; compatible PV power up to 320 W (12 V battery) / 640 W (24 V battery).
• Monitoring metrics: panel and battery power, voltage and current; energy counter; temperature monitoring.
• Built‑in temperature sensor for temperature‑compensated charging and temperature display.
• Full electronic protection functions (overcharge, over‑discharge, short‑circuit, reverse polarity, over‑temperature).
• Enhanced monitoring and charging/load control for reliable system management.
• Self‑consumption: 8 mA.
• Working temperature: -10 °C to +60 °C.
• Wire size: suitable for cable up to 10 mm².
• Physical: size 15 x 12 x 5 cm; weight 500 g.
• Multiple mounting holes for easy installation.
• Compatible battery types: sealed, AGM, gel and flooded lead‑acid batteries.
