EPEVER Solar Regulator / Controller, Model MPPT 40A MPPT, 12V 24V

Description

The 40A Maximum Power Point Tracking ( MPPT) controller increases charging efficiency by up to 30% compared to a PWM(Pulse Wave Modulation) controller. This MPPT model automatically adjusts the operating voltage and makes the PV panels work constantly at maximum power point throughout the day.

The EPEVER charge controller is equipped with an LCD display for parameter display and device configuration.
