This charge controller is designed for solar DC pump and use a dedicated high-speed control chip,Using one-button switch to complete the automatic pumping and battery charging control, With over-current protection, short circuit protection, unique anti-reverse protection, full automatic shutdown protection,automatic recovery and other full-featured protection measures,detailed charge indication, battery status, load and various fault indications. The controller through the high water level, low water level, common detection. When the water is below the low water level, the controller controls the pump to work, when the pumping water level reaches the high water level, the automatic shut down the pump stops pumping, thus realizes the intelligent control of the solar energy automatic pumping.Winter when the water pipe icing, and in the water pipe to install a ice bucket, when pressed ice bucket button, the system automatically open ice melting function, after 3 minutes, ice melting and controller automatic closed. If it does not meet the requirements,please continue to press melt ice button to continue to melt ice. The controller through the battery voltage, ambient temperature and other parameters related to the battery capacity of the sample, through a dedicated control model to achieve in line with the battery characteristics of the discharge rate, temperature compensation correction of high efficiency and high accuracy control, and the use of efficient PWM battery Of the charging mode, to ensure that the battery work in the best state, greatly extending the battery life.

Notes: If you use the ice melting function, you need to connect the ice plate to the 7/8 port, ice maker voltage DC24V, power should be less than 300w.
1） With high-performance single-chip control of water pumps and PV charging, to achieve the intelligent control.
2） The battery discharge rate characteristics of the battery charge and discharge control. The discharge voltage is a control point corrected by the discharge rate curve, eliminating the inaccuracies of the simple voltage control over-discharge, in line with the inherent characteristics of the battery, that is, different discharge rates have different voltage control points
3） With over charge, over discharge, electronic short circuit, the unique anti-reverse protection and other automatic control; the above protection does not damage any parts, do not burn insurance.
4） Using the series PWM charging the main circuit, so that the charging circuit voltage loss
than the use of diode charging circuit reduced by nearly half, the charging efficiency than NON-PWM can be up to 3% ~ 6%, increased power consumption; over discharge recovery to enhance the charge, Normal straight, floating automatic control system to make the system have a longer life; at the same time with high precision temperature compensation
5） Intuitive LED indicates the current battery status, allowing users to always understand the use of batteries
6） All control system use industrial chip (only for I industrial controller), in cold, high temperature, humid environment to run freely. At the same time the use of crystal timing control, timing control accuracy7） Using the digital LED display and settings, one-button operation to complete all settings, the use of extremely convenient and intuitive.
