Key Features of Sunchonglic 20A PWM Solar Charge Controller
High-efficiency PWM charging algorithm maximizes battery life and solar power utilization. Durable ABS flame-retardant casing with heat dissipation design ensures safe operation in harsh environments. Precise 12V/24V auto-detection and compatibility with gel, sealed, and flooded lead-acid batteries. Ultra-low standby consumption (≤13mA) for energy-saving performance in off-grid solar systems. LCD display with intuitive LED indicators for real-time voltage, current, and charging status monitoring. Advanced multi-stage charging (boost, float, equalization) prevents overcharge and deep discharge. Weatherproof construction (IP32-rated) ideal for RVs, boats, cabins, street lights, and remote power setups. Compact yet robust design with screw terminal connections for secure 20A current handling. Certified compliance with CE and RoHS standards for reliable global use. Backed by wholesale pricing—bulk orders available for commercial solar projects and resellers.
