  • NPP Tracer AN Series MPPT Solar Charge Controller
    2018-09-11

    The Tracer AN series. Based on common negative design and
    advanced MPPT control algorithm, with LCD displaying running
    status, this product is artistic, economical and practical. Improving
    the MPPT control algorithm further, Tracer AN series can
    minimize the maximum power point loss rate and loss time,
    quickly track the maximum power point of the PV array and obtain
    the maximum energy from solar modules under any conditions;
    and can increase the ratio of energy utilization in the solar system
    by 10%-30% compared with a PWM charging method. The
    limitation function of the charging power and current and reducing
    charging power function automatic improve the stability which
    works even connecting oversize PV modules and in high
    temperature, and increase the professional protection chip for the
    communication port, further improving the reliability and meeting
    the different application requirements.
