    LCD Display Digital Solar Charge Controller Pulse Width Modulation Charging
    SRNE 12/24v 40A pwm solar regulator with USB port HP2440
    Product Overview

    Pulse Width Modulation(PWM) charging method is to charge the battery by automatically changing the duty cycle pulse current, so that the pulsating charging can make the battery more safe and fast full of power, and the disconnection period makes the battery react with the oxygen and hydrogen generated by the chemical reaction. It is absorbed, so that the concentration polarization and the ohmic polarization are naturally eliminated, thereby reducing the internal pressure of the battery and allowing the battery to absorb more power. The pulse charging method enables the battery to have sufficient reaction time and improves the acceptance rate of the battery to the charging current.
    An upgraded 3-stage PWM charging algorithm is adopted. Application of an equalizing charge to the battery periodically or when over discharged, can effectively prevent the battery from non-equalization and sulfuration, thus extending the battery's service life (with the exception of GEL and lithium batteries).
    This model HP2440 is with LCD display so that the users can monitor the parameters of solar equipments . It is also with USB port and the users can charge their phones or other USB equipments 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.
