Characteristics of solar energy controller

1. Intelligent control is achieved by using microcontrollers and special software;

2. Accurate discharge control using battery discharge rate characteristic correction. The discharge terminal voltage is the control point corrected by the discharge rate curve, which eliminates the inaccuracy of simple voltage control over discharge, and conforms to the inherent characteristics of the battery. C'est, different discharge rates have different end voltages;

3. It has fully automatic control of overloading, overdischarge, electronic short circuits, overload protection, and unique anti-reverse connection protection; all the above protections do not damage any parts and do not burn the fuse;

4. The use of PWM series charging main circuit, so that the charging circuit voltage loses more than the use of diodes in the charging circuit to reduce the voltage loss of nearly half, charging efficiency is higher than non-PWM 3% -6%, increasing the power time; over-discharge recovery de lifting charging, normal direct charging, floating charging automatic control mode to make the system longer service life; en même temps, with high precision temperature compensation;

5. Intuitive LED light tube to indicate the current battery status, so that users understand the use of the situation;

6. All controls all industrial-grade chips (only for use with an industrial-grade controller), can run freely in cold, haute température, humid environment. En même temps, the use of crystal timing control, timing control is accurate;

7. Cancelled the potentiometer adjustment control set point, and the use of E-square memory to record the work of the control point, so that the setting digitization, eliminating the potentiometer due to vibration bias, temperature drift, etc., so that the error control point reduces the accuracy and reliability of the factors;

8. With the use of digital LED display and setup, one-key operation can complete all the settings, the use of an extremely convenient and intuitive role is to control the entire system’s working state, and the battery plays the role of overcharge protection, overdischarge protection. In places with large temperature differences, qualified controllers should also have the function of temperature compensation. Other additional features such as the light control switch, time control switch should be optional controllers.
