GENERAL RECOMMENDATIONS selecting the solar controller The solar charge controller is the central component in a standalone system. It controls the energy flow in the entire system and determines the system function and service life. This means that a suitable solar charge controller must be selected carefully. The solar charge controller only accounts for between 3 % and 5 % of the total cost of a stand-alone system, and yet it is the most important component. A high-quality, reliable solar charge controller in a higher price class pays for itself very quickly, as it increases the battery...

Sine wave inverters In contrast to so-called square wave or trapezoidal inverters (grey square curve), Steca sine wave inverters produce a real and precisely controlled sine wave (red sine wave) at their output. The sine wave inverters assure that all loads which are suitable for grid operation can also be operated on a solar home system without any problems. Furthermore, they offer the advantage that no significant noises are produced in the inverter and there is no loud background noise to be heard on a connected radio, for example. Selecting an inverter The power of the inverter must be...

for Steca solar charge controllers Steca offers an innovative, integrated RS-485 communication interface, the StecaLink bus. This interface allows a charge controller to act as a communication master (e.g. Steca Tarom MPPT 6000-M) to exchange measurements and setting information with other devices (e.g. Tarom MPPT 6000-S, Steca Tarom 4545/4545-48 and/or PA HS400). In the StecaLink communication system, the master collects all relevant data of the other controllers or electricity sensors, to record them in the data logger. Optionally, it can also calculate the battery's state of charge as a...

The Steca PR 10-30 series of charge controllers is the highlight in the range. Use of the latest charging technologies combined with state of charge determination enable optimal battery maintenance and module power monitoring. A large display informs the user about all operating modes with the aid of symbols. The state of charge is represented visually in the form of a level meter. Data such as voltage, current and state of charge can also be displayed digitally as figures on the display. In addition, the controller has an energy meter which can be reset by the user.
