40A MPPT Solar Charge Controller RV Charging

High Performance: 12v solar panel regulator uses 32-bit high-speed industrial computing technology, as well as advanced MPPT control algorithms, which can quickly track the maximum power point of the photovoltaic array in any environment, so that the maximum energy conversion can be obtained in the solar cell, significantly improving the utilization rate of the photovoltaic array.

Solar Panel Regulator: The digitally controlled three-stage adaptive charging mode of the solar charge regulator effectively extends battery life and improves system performance.

Solar charge controller: The combination of the charge controller's large screen and four buttons improves the information exchange rate between man and machine.

Wide Application: The intelligent temperature control circuit of the solar controller can effectively protect the normal operation of the machine in a high temperature environment. It can be used in communication base stations, home power systems, traffic lights, solar street lights, garden lighting systems, etc.
