SKU: SD-PWM-12/24V-20A-IP65
SD-PWM-12/24V-20A-IP65 20 A PWM Charge ControllerIP65 Waterproof | Auto 12/24 V Detection | Canadian All-Weather Reliability
Harness your Canadian solar array with confidence using the SD-PWM-12/24V-20A-IP65. Its advanced MCU-controlled PWM algorithm delivers up to 98 % conversion efficiency for faster, cooler charging—whether you’re on an Arctic cabin or a Maritime cottage. The IP65 rugged enclosure keeps rain, dust, and snow out, while auto-voltage detection switches seamlessly between 12 V and 24 V battery banks.
Advanced PWM ControlMCU-driven pulse-width modulation maximizes charge efficiency and minimizes heat, extending component life.
Multi-Chemistry CompatibilityOptimized charging profiles for LiFePO₄, LTO, Gel, AGM, flooded (WET), and calcium batteries—no manual switches required.
Built-In Overcharge & Over-Discharge ProtectionIntelligent voltage regulation prevents premature battery failure; reverse-current blocking stops drain at night.
Automatic Equalization & Float ChargingPeriodic boost and float cycles maintain capacity on deeply discharged lead-acid banks—ensuring years of reliable service.
Night-Time Battery GuardSpecial circuitry blocks reverse discharge when panel voltage falls below battery voltage under low-light or snow-covered conditions.
Intuitive LED & LCD DisplayReal-time readout of battery voltage, charging current, state-of-charge (Ah), battery type selection, and fault codes.
Comprehensive Safety ProtectionsReverse-polarity, short-circuit, over-voltage, over-temperature, and multi-stage charge safeguards keep you and your system safe.
Flexible InstallationIP65-rated die-cast aluminum housing for surface-mount use; optional flush-panel mounting hardware available.
Rugged, Canadian-Ready DesignConformal-coated circuit boards and plated terminals resist corrosion, humidity, and salt spray from coast to coast.
Easy setup, and coast-to-coast Canadian shipping make the SD-PWM-12/24V-20A-IP65 the perfect companion for your 12 V or 24 V off-grid battery system. Add to Cart today!
