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.
