Product Description

12V/24V 20A Dual USB-5V/2A Light+Timer control Solar Controller/Regulator Sm20

CM20-20A / CM30-30A

This is a new intelligent solar controller, which is equipped with industrial-grade STM 8 microprocessor to control the charge and discharge process. And, it has perfect and liable battery charge and discharge period management. The charge circuit is characterized by high efficiency and low consumption by controlling the MOSFET of the ultra-low internal resistance with PWM. This controller has multiple load control modes and is adaptable to different industries.
