Steca Solsum

The Steca Solsum F-Line continues the huge success of one of the most used SHS controllers. With a power range of up to 10 A at automatically recognized 12 V or 24 V it fits to a system sizes of maximum 240 W.

The circuit board is completely electronically protected and with the LED user interface it is easy to check the battery state of charge at any time.  Large terminals guarantee a simple connection of solar panels, battery and load. The Steca Solsum F works on PWM as a low loss series controller.

  • Diode protection to prevent reverse current from the solar panel in darkness
  • Efficient PWM voltage regulation (pulse-width modulation)
  • LED System Indicators
  • Low voltage disconnect feature to maximum load current rating of the model
  • Temperature compensation for accurate voltage sensing
  • Reverse polarity protection
  • Automatic system detection for 12V or 24V systems.

The PR Range and Tarom range incorporate the following additional features

  • Digital display of battery volts or state of charge
  • Digital display of charge and load currents
  • Digital display of accumulated ampere hours charged and drawn

Steca Solarix MPPT

Steca Solarix is a solar charge controller with maximum Power Point tracking. The  advanced  MPP-tracking  algorithm  from  Steca  assures  that the  maximum  available  power  of  the  solar  generator  is  charged to  the  batteries. These regulators allow the connection of large grid-connect panels to batteries. The Solarix MPPT 2010 is perfect for connecting a 250W panel to a 12V system.

  • Maximum Power Point Tracker (MPP tracker)
  • Voltage and current regulation
  • PWM control
  • Current compensated load disconnection & Automatic load reconnection
  • Temperature compensation
  • Monthly maintenance charge
