1. The solar charge controller uses a microprocessor and a dedicated control algorithm to realize intelligent control.

2. Five load working modes: pure light control, light control + timing, manual, debugging mode, and normally open mode.

3. The solar charge controller has a discharge rate correction control, and different discharge rates have different termination voltages, which are in line with the inherent characteristics of the battery.

4. Scientific battery management method. When over-discharge occurs, the battery is charged with a boost voltage and a compensation maintenance is performed. During normal use, use a combination of direct charging and floating charging, and boost charging every 7 days. It prevents the battery from being vulcanized and greatly extends the service life of the battery; at the same time, it has high-precision temperature compensation.

5. Parameter setting has the function of power-off saving, that is, important data such as system mode and control parameters are saved inside the chip, and will not be lost after power-off, making adjustment more convenient and system work more reliable.

6. The charging circuit adopts a dual MOS series control circuit, which reduces the circuit voltage loss by nearly half compared with the circuit using a diode. The charging adopts PWM fuzzy control, which greatly improves the charging efficiency and greatly increases the power consumption time.

7. LED visually displays the status of solar cells, storage batteries and load, and the digital tube displays the adjustment parameters, allowing users to understand the operating conditions of the system in real time, and has a wealth of parameter settings, users can set the corresponding working mode according to different use environments.

8. With overcharge, overdischarge, overload protection and unique electronic short circuit protection and anti-reverse protection, all protections will not damage any parts, and no insurance will be burned; TVS lightning protection, no jumper design, can improve the reliability of the system Performance and durability.

9. All controls use industrial-grade chips and precision components, which can operate normally in cold, high temperature, and humid environments. At the same time, crystal oscillator timing control is used to make the timing control more accurate.

10. The solar charge controller uses digital LED display and settings, and all settings can be completed by one-button operation, which is convenient and intuitive to use.

The solar charge controller is specially designed for solar DC power supply systems, solar DC street light systems, and small solar power station systems. It uses dedicated computer chips to achieve intelligent control. All chips are industrial-grade and can be used in harsh environments. At the same time, the system has full-function protection measures such as short circuit, overload, and unique anti-reverse connection protection, full-featured, over-discharged automatic shutdown, recovery and other full-featured protection measures, detailed charging instructions, battery status, load and various fault instructions. The solar charge controller samples the battery voltage, photovoltaic cell voltage, discharge current, ambient temperature and other parameters through the computer chip, and calculates through a special control model to achieve high-accuracy control of the discharge rate and temperature compensation correction that meets the characteristics of the battery, and adopts intelligent and efficient The PWM fuzzy charging method is adopted to charge the battery, and the 7-segment voltage control is adopted to ensure that the battery is working in the best condition and greatly extend the service life of the battery.
