This industrial-grade PWM solar charge controller delivers robust battery protection and reliable performance for off-grid systems. Engineered for 12V or 24V setups with automatic voltage detection, it safeguards deep-cycle batteries while maximizing solar harvest. Here’s why it’s a trusted solution for entry-level solar installations:
Smart PWM Charging: Pulse Width Modulation technology optimizes battery absorption and float stages. Extends lead-acid/GEL battery lifespan by preventing overcharging, deep discharge, and reverse current leakage at night
Multi-Layer Safety: Integrated protection against short-circuit, reverse polarity, overcurrent, and over-temperature events.
Automatic 12V/24V Recognition: Instantly detects battery voltage without manual configuration. Supports solar panels up to 360W (12V) or 720W (24V)
