Optimize your solar street light system with this 20A PWM Solar Charge Controller featuring intelligent SOC control and dual voltage compatibility (12V/24V). Advanced temperature compensation using external sensors ensures precise battery management in extreme environments (-20C to 60C). Multi-protection system includes overcharge prevention, short circuit protection, and reverse polarity safeguard with zero component damage during activation. High-efficiency PWM charging reduces voltage loss by 50% compared to diode-based systems, increasing energy conversion rate by 3-6%. Dual LED displays provide real-time battery status monitoring and one-touch programming for customized lighting schedules. Industrial-grade components rated for IP65 durability, supporting 6mm cables with 9.5mm terminal spacing for secure outdoor installations. Integrated half-power mode extends runtime by 30% through automatic midnight power reduction in LED street lighting systems. Universal compatibility with lead-acid, gel, and lithium batteries (up to 200W solar input).
