Steca Solarix MPPT

Description

Steca Solarix MPPT are solar charge controllers with maximum power point tracking. These are suitable for all common module technologies and are the ideal fit for solar systems with module voltages higher than the battery voltage. In particular, this means that inexpensive PV modules that are used for grid-connected systems can also be used autonomously.

The efficient MPP tracking algorithm from Steca always provides the maximum usable power of the module and therefore significantly increases the energy yield, especially in poor weather conditions (cloud cover, winter, diffused light). The Steca Solarix MPPT charge controllers combine state-of-the-art charging technology with high efficiency, professional battery maintenance with numerous setting options, a modern design, excellent protective functions and an intuitive LC display with menu navigation.
