Steca Solarix MPPT
MPPT 2010
Steca Solarix MPPT 2010 is a solar charge controller with Maxi-
mum 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 from Steca assures that the maxi-
mum 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.

Steca Solarix
2401, 4401
The solar charge controllers Steca Solarix 2401 and 4401 are
optimally suited for inverter systems. The controller combines
basic solar charger functions with a 40 A high-performance
charge controller. It is available as 12 V / 24 V and 48 V system.
This makes the solar charge controller very cost effective.
The load current is limited to 10 A. The charging processes
are based on the voltage level, which can be individually set
with the help of four buttons behind the front casing.

**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.
