Steca Solarix MPPT is a solar charge controller with Maxi­mum Power
Point Tracking. It is specially designed to work with all established
module technologies and is optimized for solar systems with module voltages higher than the battery voltage. The Steca Solarix MPPT is especially qualified in combination with grid tied solar modules. The advanced MPP-tracking algorithm from Steca assures that the maximum available power of the solar generator is charged
to the batteries. The Steca Solarix MPPT with latest technology
ensures full performance in all conditions, a professional battery
care combined with modern design and excellent protection.

  • Inverters must not be connected to the load output.
  • CAUTION: If an open circuit voltage of more than 75 V or 100 V is supplied to the connected solar module, the controller will be destroyed. When selecting the solar module, it is important to bear in mind that the open circuit voltage should never exceed 75 V or 100 V over the entire working temperature range. When using solar modules with a maximum open circuit voltage of between 60 and 100 V (over the entire temperature range), all installation steps must be carried in accordance with protection class II.
