Auto 48V 40A LCD&LED MPPT Solar Charge Controller (QWM-4840CAP)
Product Introduction:
MPPT controller is a kind of intelligent, multi-purpose solar charge controller. It uses the fixed LCD
Display, with a very friendly interface; Various control parameters can be flexibly set, fully meet your various
Application requirements. MPPT controller has following features:
(1) MPPT function: The most important feature of this controller is intelligently tracking input voltage from
Solar panels, and this can let solar panels always work at Maximum Power Point of V-A curve. Co***red
With normal solar charge controller, this MPPT controller can increase the generating efficiency of solar
Panels by 10% to 50%.
(2) Vivid LCD screen signal and precise operation.
(3) Intelligent PWM charging mode with auto temperature compensation.
(4) Adjustable charging and discharging parameters, and settable load working state.
(5) Different protection function for battery, including protection against reverse charging for battery, battery low voltage protection and protection against battery reverse connection.
