Overview: 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 . The limitation function of the charging power and current and reducingcharging 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. Advanced MPPT technology, with efficiency no less than 99.5% Advanced MPPT control algorithm to minimize the maximum power point loss rate and loss time type: 40A Ultra-fast tracking speed and guaranteed tracking efficiency Wide operating voltage range High quality components, perfecting system performance, with maximum conversion efficiency of 98% Accurate recognition and tracking of multiple-peaks maximum power point high quality and low failure rate, which can the product's service life Charging power and current limitation function Compatible with lead-acid and lithium-ion batteries Battery temperature compensation function Real-time energy statistics function Overheating power reduction function Multiple load work modes The communication port adopts professional protection chip, which can provide 5VDC power supply, and has over-current and short-circuit protection. With -485 communication bus interface and Modbus communication protocol, it is available to meet various communication requirements in different situations. Monitor and set the parameters via mobile phone APP or PC software Full-load operation without any drop in capacity within the range of working environment temperature Extensive electronic protection Material: plastic colour: White Package Contents: 1 x MPPT Solar Charge Controller Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
