Whether off-grid PV systems, inverters or storage systems, Steca solar electronics impresses with smart devices and new features designed to increase user friendliness and reduce costs.

Steca will present its extensive product portfolio for the 17th time, impressing visitors with innovations in the fields of off-grid and grid-feed systems. This year, the Steca inverters excel through optimized performance: For instance, a special smart meter, which allows for intelligent control of the feeding power, can be connected to a new interface. This new feature is a crucial requirement for integration into smart grids on international markets.

Another novelty is the completely revised integrated web server that allows end customers to analyse inverter data in a cost efficient, user-friendly and even more graphic way. Furthermore, Steca has introduced optimised error detection via a generator characteristic curve that can be called up on the inverter's display. This is a particularly user-friendly function.

The Global MPP Tracking function, which has also been enhanced, ensures optimum shade management for significantly higher yields. coolcept inverters are easy to use and reduce the costs of the overall system while boosting yields.

StecaLink bus – communicative charge controllers

Communication is key, which is why Intersolar visitors will be positively surprised by this year's innovative integrated RS-485 communication interface, the so-called StecaLink bus. In off-grid systems, this interface allows the charge controller to act as communications master and exchange measurements and setting information with other devices. This makes for a complex system that collects and records all information in a central place.

Optionally, it can also calculate the battery's state of charge as a percentage (SOC). These highlights also help to reduce costs by saving on additional components as well as ensuring application flexibility and raising the system's service life thanks to optimized battery maintenance. StecaLink bus: This ability to link multiple devices and their data creates a connected system which collects and records all information in a central place.

Storage systems – full speed ahead

One of Steca Elektronik's core competencies is the use of power electronics in battery systems. At the Intersolar, the electronics specialist will present both a complete storage system based on coolcept devices and the various application options for electronic components in various storage systems.

Solar thermal applications – adapted for the future

In 2016, solar industry experts may once again assure themselves of the user friendliness of Steca's solar thermal controllers. The current ErP Directive remains a controversial subject with uncontrolled pumps having been prohibited since August 2015. Since all Steca controllers have complied with the current Directive since last year, the electronics enterprise is holding all the cards.
