Steca Solarix MPPT are solar charge controllers with maximum power point tracking. They suit all common module technologies and are ideal for solar systems where the module voltage is higher than the battery voltage. In particular, this means low-cost PV modules made for grid-connected systems can also be used in stand-alone systems.
Steca’s efficient MPP tracking algorithm always delivers the maximum usable module power and so significantly increases energy yield, especially in poor weather (cloud cover, winter, diffuse light). Steca Solarix MPPT charge controllers combine the latest charging technology and high efficiency, professional battery care with many setting options, modern design, excellent protection functions and an intuitive LC display with menu navigation.
