Protection Does Not Damage Any Parts And Does Not Burn Insurance

- May 17, 2018 -

Solar panels are the core part of solar photovoltaic systems. The function of solar panels is to convert the solar energy into electrical energy, and then output the direct current into the storage battery. Solar panels are one of the most important components in solar photovoltaic systems. Their conversion rate and service life are important factors that determine whether solar cells have value in use. Component Design: Designed according to the International Electrotechnical Commission IEC:1215:1993 standard, 36 or 72 polysilicon solar cells are used in series to form 12V and 24V various types of components. The module can be used for various household photovoltaic systems, independent photovoltaic power plants and grid-connected photovoltaic power plants.

1, using a single-chip microcomputer and special software, to achieve intelligent control;

2. Accurate discharge control using battery discharge rate characteristics correction. The end-of-discharge voltage is a control point that is corrected by the discharge rate curve, eliminating the inaccuracy of a pure voltage-controlled overdischarge, which is consistent with the inherent characteristics of the battery, ie different discharge rates have different end voltages.

3, with overcharge, over discharge, electronic short circuit, overload protection, unique anti-reverse protection and other automatic control; the above protection will not damage any parts, do not burn insurance;

4. A series PWM main circuit is used to reduce the voltage loss of the charging circuit by nearly half compared to the diode-based charging circuit. The charging efficiency is 3% to 6% higher than that of the non-PWM, which increases the power consumption time and improves the overdischarge recovery. Charging, normal direct charge, floating charge automatic control system makes the system have a longer service life; at the same time, it has high-accuracy temperature compensation;

5, Intuitive LED LED indicates the current battery status, allowing users to understand the status of use;

6, all control all use industrial-grade chips (only with industrial grade I controller), can run freely in cold, high temperature, humid environment. Crystal oscillator timing control is used at the same time, timing control is precise.

7, cancel the potentiometer adjustment control set point, and the use of the E-side memory record the work control point, so that the set of digits, eliminating the potentiometer vibration offset, temperature drift so that the control point error to reduce the accuracy and reliability Sexual factors;

8. The use of digital LED display and settings, one-button operation to complete all settings, the use of extremely convenient and intuitive role is to control the working status of the entire system, and played a role in the battery over charge protection, over discharge protection. In areas with large temperature differences, qualified controllers should also have temperature compensation. Other additional functions such as light control switch, time control switch should be optional controller;
