This 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 2010 is especially qualified in combination with grid tied solar modules. The advanced MPP-tracking algorithm assures that the maximum available power of the solar generator is charged to the batteries. The Steca Solarix MPPT 2010 with latest technology ensures full performance in all conditions, a professional battery care combined with modern design and excellent protection.

**CAUTION: If an open circuit voltage of more than 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 100 V over the entire working temperature range.
When using solar modules with a maximum open circuit voltage of between 75 and 100 V (over the
entire temperature range), all installation steps must be carried in accordance with protection class II.
