Tracer-AN(10A~40A)series charge controller adopts MPPT(Maximum Power Point Tracking)technology. In any situation, it can track the maximum power point (MPP) of the solar array and obtain the maximum solar energy rapidly and accurately. It can generate up to 30% more power compared with the PWM charge controller. This series can accept max.100V Voc and work with the solar panels which are designed for on-grid applications. The multi-functional LCD displays the system status vividly.
