The solar charge controllers with Maximum Power Point Tracking, MPPT for short, increase the efficiency of the solar panels. The operating point varies constantly depending on the external conditions (solar radiation and temperature) to which it must adapt (tracking). They ensure optimal utilization through: . Tracking efficiency and efficiency up to 99% 4-step charging curve for longer battery life. 8 predefined battery charging curves, suitable for all common battery systems. Fully configurable system
