Product Description

12V/24V 20A PWM Solar Charge Controller (QWP-1420T)

Solar charge controller is the most important part of the solar system. It is too intelligent and automatically to control the charge, discharge and load of the system. The performance of the controller can influence the stability of the system, especially the lifetime of Battery. 

1. System Description: 

1). The solar controller is designed for solar DC power supply system, DC solar street light system, to use professional intelligent chip to control it. 

2). To use one button light touch switch to finish all the manipulation and settings. 

3). The controller has many protective functions, for exsample, short circuit, over load, wrong connection, over charge, over discharge, suto cut, auto recovery etc. 

4). With detailed charging battery state, load, and breakdown signal LEDs. 

5). It can high precisely control cos of the chip can get battery data such as voltage, discharge current, environment temperature etc. 

6). It uses PWM battery charging mode, to assure the battery at its best state and prolong its life span. 

7). It has many working modes, discharge choices, to meet different users' needs. 

2. Main Features: 

1). Intelligent control with single chip and professional software. 

2). With precise battery discharge control by use of battery discharge features. Different discharge rated with different final voltage. 

3). With over-charge, over-discharge, short circuit, over-load, worng connection auto protection. 

When the above mention functions work, it won't destroy any components of the controller, it won't burn the use. 

4). To use series connection PWM circuit, it is 3%-6% more effective than non-PWM circuit when charging. To use float charging control mode to prolong the system life span; with high precision temperature compensation function. 

5). With digital display of work mode and LED's of solar system

6). To use industrial grade chip, it can work under environment such as cold, high temperature and humid; at the same time, it uses a crystal oscillator timing control, the timing control accurately. 

7). To use flash memory to keep record of all the working control point, to make the settings digitalized. 

8). With DC discharge or IHZ strobe flash discharge mode which is especially suitable for traffic light control etc.
