30/20/10A 12/24V Auto Work Solar Charge Controller PWM with LCD Dual USB 5V Output Solar Cell Panel Charger Regulator Controller


Solar charge Controller with dual USB ports.

Settable operating modes of loads, fully 4-stage PWM charge management.

The solar regulator is only suitable for lead acid batteries:OPEN, AGM, GEL, not for nickel hydride, lithium, Liions, or other batteries. For protecting the lifespan of your battery, once the voltage of the battery drop below 8V, the solar controller will turn off automatically
