The solar controller is called the solar charge-discharge controller, which is an automatic control device used in a solar power generation system to control the multi-channel solar battery array to charge the battery and the battery to power the solar inverter load. It regulates and controls the charge and discharge conditions of the battery, and controls the power output of the solar cell module and the battery to the load according to the power demand of the load. It is the core control part of the entire photovoltaic power supply system.
The solar control system consists of solar panels, batteries, controllers and loads.
1. Power adjustment function; 2. Communication function: 1 simple indication function 2 protocol communication function such as RS485 Ethernet, wireless and other forms of background management; 3. Perfect protection function: electrical protection reverse connection, short circuit, over current, etc.
main feature: 1.Using single-chip microcomputer and special software to realize intelligent control;
2. Accurate discharge control using battery discharge rate characteristics correction. The end-of-discharge voltage is a control point modified by the discharge rate curve, eliminating the inaccuracy of pure voltage control over-discharge, which is consistent with the inherent characteristics of the battery, that is, different discharge rates have different end-voltages;
3. Fully automatic control with overcharge, overdischarge, electronic short circuit, overload protection, unique anti-reverse protection, etc .; the above protections will not damage any components and will not burn insurance;
4. The series PWM charging main circuit is adopted, which reduces the voltage loss of the charging circuit by nearly half compared with the charging circuit using a diode, and the charging efficiency is 3% -6% higher than that of non-PWM, which increases the power consumption time; the improvement of over-discharge recovery Charging, normal direct charging, and floating charging automatic control methods make the system have a longer service life; meanwhile, it has high-precision temperature compensation;
5.Intuitive LED luminous tube indicates the current battery status, let users know the usage status;
6. All controls use industrial-grade chips (only for industrial controllers with I), which can run freely in cold, high-temperature and humid environments. The crystal timing control is used at the same time, and the timing control is accurate;
7. Canceled the potentiometer adjustment control set point, and used the E square memory to record each working control point, digitizing the settings, eliminating the control point errors due to potentiometer vibration deviation, temperature drift, etc., reducing accuracy and reliability. Sexual factors
8. Using digital LED display and settings, all settings can be completed with one-click operation. The extremely convenient and intuitive use is to control the working status of the entire system and to protect the battery from overcharge and overdischarge. In places with large temperature differences, qualified controllers should also have the function of temperature compensation. Other additional functions such as light switch and time switch should be optional for the controller.
