Color option: 3 Overview This solar charge controller supports 12 V and 24 V battery systems and combines MPPT and PWM functionality for efficient solar charging. It features a large LCD for real time system information and dual USB outputs for charging small devices. Key benefits Higher solar harvest and fast tracking: advanced MPPT/PWM technology with tracking efficiency not less than 99.5 and maximum conversion efficiency up to 98 improve energy yield from PV panels. Clear system monitoring and simple setup: large LCD shows charge and discharge currents, cumulative generation, discharge power, temperature, and provides adjustable charge and discharge parameters with poweroff memory. Flexible device charging: dual USB outputs (5 V) for phones and accessories, typical 2 A per port and maximum combined USB current up to 2.5 A for simultaneous charging. Reliable protection and recovery: builtin protections for overcharge, overdischarge, short circuit, reverse connection, overcurrent, open circuit and overheating, with selfrecovery to prevent controller damage. Wide operating range: supports cold to hot climates with operating temperature from minus 35 to 60 C and low standby consumption.
