    Product Description

    Features of SR-ML4830

    1. Advanced double-peak or multiple-peak tracking technology. When the panel has a shadow block or a part of the panel is damaged, I-V curve shows multiple peaks. The solar charge controller can still accurately track the maximum power point.
    2. Built-in algorithm for maximum power tracking. This significantly raises energy utilization efficiency of photovoltaic systems, with charging efficiency 15% ~ 20% higher than traditional PWM solar charge controllers.
    3. MPPT tracking efficiency can be as high as 99.9%.
    4. Advanced digital power technology, with circuit energy conversion efficiency as high as 98%.
    5. Supporting charging procedures of gel batteries, sealed batteries, open batteries, lithium batteries and other types of batteries.
    6. Current-limiting charging mode. When the power of a solar panel is too large, and the charging current is greater than rated current, the solar charge controller automatically reduces charging power, thereby making the solar panel work at rated charging current.
    7. Supporting automatic identification of battery voltage.
    8. LED indicator of malfunction, buzzer alarm, and liquid crystal display of abnormal information. This helps users identify system failures.
    9. Supporting historical data storage for up to 5 years.
    10. LCD screen display function. The display enables users to view equipment operation data and status, and modify controller parameters at the same time.

    Q: How many charging mode does the controller have?
    A: There are two charging modes. There are PWM and MPPT. MPPT is the most advanced. Srne have already developed MTTP charge controller with high performance, reliability, efficiency and fast tracking speed.

    Q: What's the difference of the PWM charge controller and MPPT charge controller?
    A: 1. MPPT controller uses maximum power tracking technology, compared to the PWM controller, the MPPT can generate more electricity with the same solar panels.
    2. MPPT controller has low requirement of solar power system voltage, if the line or component parts damage the voltage, using MPPT controller does not affect the system generating.
    3. MPPT controller can detect the temperature of the battery, then adjust the temperature by itself, the solar panel can charge the battery more efficiency.

    Q: Why should the controller have temperature compensation function?
    A: As temperature rises, electrochemical activity in the battery increases. Similarly, as temperature falls, electrochemical activity decreases. Therefore, as temperature rises, charging voltage should be reduced to prevent overcharge, as temperature falls, charging voltage should be increase to avoid undercharge. In general, to assure optimum service life, use of a temperature compensated charger is recommended.

    Q: How does your factory carry out quality control?
    A: Quality is our priority. Our QC always attached great importance to quality control from the very beginning to the end of the production. Each product will be fully assembled and carefully tested before packed.
