Thanks for selecting 20A 12V/24V our solar charge controller. This controller is a PWM charge controller with 12V/24V automatic identification with the most advanced digital technique and represents the latest level of development of photovoltaic technology products.

 

The PWM Technology


Pulse Width Modulation (PWM) technology for battery charging. Battery charging is a current based process so controlling the current will control the battery voltage. For the most accurate return of capacity, and for the prevention of excessive gassing pressure, the battery is required to be controlled by specified voltage regulation set points for Absorption, Float, and Equalization charging stages. The charge controller uses automatic duty cycle conversion, creating pulses of current to charge the battery. The duty cycle is proportional to the difference between the sensed battery voltage and the specified voltage regulation set point. Once the battery reached the specified voltage range, pulse current charging mode allows the battery to react and allows for an acceptable rate of charge for the battery level

 

Product features:


Using Single Chip Microcomputer and specialized software make it smart control.

The controller is made by PWM technology, the voltage loss the charging circuit is less nearly half than using diode charging circuit, charging efficiency is 3% higher than Non-PWM, increases the power use of time; the improving charge of Discharge recover, normal direct charge, floating automatic control mode will extend the battery life

Intuitive LCD display interface, allowing users to understand the use of the situation. Well.

All controls are made by the industrial-grade chip, can run freely in cold, high temperature, humid environment.

One stop solution design with a key operation, to make it more easy and convenient to use

Built in 12V/24V battery automotive identification function

With two 5V USB output, can meet all electronic appliance with 5V input voltage
