Collection: Steca

This enables small DC appliances such as chargers, radios & computer games etc. to be powered from a 12 or 24 V battery system with an output that can be switched to 12, 9, 7.5, 6, or 3 volts. Max output current is 1.5 A depending upon input & output voltages.

Remote graphical display for the Steca Solarix 2020-x2 solar charge controller. Energy flow is displayed as a graphic, making it intuitively understandable. Includes comprehensive data logger enabling full monitoring of the entire system. Virtually all charge controller parameters can be set and modified which allows the distribution of charge power between the two batteries to be adjusted. For the load output, all automatic time and battery voltage functions are fully programmable.

The programming unit Steca PA RC100 allows to program Steca solar charge controllers. The values can be adjusted with the help of switches. After a restart of the charge controller the new settings can be activated by pressing the program-button on the Steca PA RC100. An LED will transfer the values to the controller.

A range of PWM solar charge regulators rated from 10-30A, ideal for any small to medium size system which adapts automatically for use in either 12 or 24 V systems. Includes automatic low voltage disconnection and a manual load switch. Protection features include an automatically re-settable electronic fuse for maintenance free operation. Includes large self explanatory LCD display showing voltage, charge & discharge current.

PWM solar charge controllers using the latest charging technologies combined with state of charge determination to enable optimal battery charging. A large display informs the user about all operating modes with the aid of symbols. State of charge is shown as a level meter and data such as voltage, current and state of charge can be displayed digitally as figures on the display.

State-of-the-art dual battery PWM charge controller that is ideal for use in leisure applications such as boats and motor homes

These controllers use maximum power point tracking and are optimally suited for solar systems with module voltages higher than the battery voltage. In particular, they enable PV modules that are used for grid-connected systems to also be used off-grid.

Simple high performance PWM solar charge controllers with modern design and a convenient LED display.

Easy to use PWM charge controller ideal for small systems with up to 10A charge/load current.

The Steca Tarom sets new standards in this power class. A graphic display informs the user about all important system data and enables configuration and adjustment of the controller to the specific requirements of the individual system for optimal control and battery protection.

Integrated data logger stores all important system data which can then be read by the minute via an open Steca UART interface.
Two additional switching contacts can be freely configured as a timer, a night light function, to start generators or as surplus management. Up to six devices can be connected in parallel and communicate with one another via the StecaLink bus.

Sophisticated 60A 12/24/48V MPPT charge controllers with 180VDC maximum input voltage

All Steca solar charge controllers have an integrated temperature sensor that makes them capable of adjusting the charging to suit temperature conditions. However, if the battery is installed in a different room to the controller a n additional external temperature sensor should be used.
