    We see consultation as a training exercise. Therefore we assist in all aspects of solar analysis, vetting, and verification.
  • System Design

    System Design

    A properly designed solution will deliver expected results. We model all our PV solutions according to customer requirements.
  • Procurement


    Cost - quality balance is a tricky thing. we stock only NRS-097 compliant equipment, at a competative price.
  • Installation and Construction

    Installation and Construction

    Installations for PV solutions are rife, but we take meticulous care that all regulatory requirements are met through our installations.
  • Customer Service

    Customer Service

    With equipment lasting more than 30 years, long term relationships is important. We want satisfied customers.
  • Remote Monitoring

Tarom Models

The new design of the Steca Tarom sets a new standard for this power class. The graphical display informs the user of important information and enables configuration of the controller to the requirements of the spesific system.

The Tarom charge controller is the ideal choice for larger systems at three different voltage levels - 12V, 24VF and 48V.

The integrated ogger stores all important operational data which can be read using an optional Steca UART interfae. An external temperature sensor is available for integration to the system.

Two switch contacts are available for programming to automate functions such as a night light, generator control, load management. Up to six devices can be connected in parallel to increase the system capacity.


  • Shunt topology
  • MicroSD Card slot for recording of operational data
  • Automatic battery voltage detection
  • PWM Control
  • SOC dependant load disconnection function
  • Automatic load reconnection
  • Temperature compensation
  • Real-time clock
  • Four programmable timers
  • Two configurable multifunction contacts
