50A solar charge controller for 12V 24V solar panel PWM

50A solar charge controller for 12V 24V solar panel PWM.

The solar charge controller is equipped with an intelligent battery protection system; Multiple protections against overcharge, over-discharge, overload, short circuit, reverse polarity, overheating and battery undervoltage.
Visual LCD graphic symbols, automatic system voltage recognition, automatic temperature compensation, short key press, intelligent PWM charging mode. Adjustable charge and discharge control parameters.
This solar collector controller with output switch, intelligent control and easy operation: connect the controller and the battery with cables of the correct polarity. The battery indicator on the controller will light up if the connection is successful; otherwise, check and connect again.
Digital microcontroller accuracy: when charging, the arrow between the panel icon and the battery icon will flash quickly; when the battery is fully charged, it will flash slowly and charging will stop. The controller's function is to protect against over-voltage and over-discharge.
Adjustable load operating modes, remote monitoring function (non-standard), battery low voltage disconnect (LVD), overload and short-circuit protection, accumulated charge and discharge time, battery over-discharge protection, battery recovers connection, with DC 12V and USB 5V output (non-standard).
