Kontron Solar GmbH, formely known as Steca Elektronik GmbH products

The Steca Solsum generation is one of the most successful and most frequently used charge controllers in solar home systems. With load currents of up to 10 A with automatic switching from 12 V or 24 V, it is ideally suited for devices with up to 240 W power. The printed circuit board is completely electronically protected and the LED display allows the battery status to be easily read. The connectors allow solar panels, battery and load to be connected easily. The Steca Solsum F operates as an energy-efficient series controller based on PWM.

The very high efficiency level results in a peak efficiency of 98.6% and a European efficiency level of up to 98.3%, which means that less power loss has to be generated and dissipated to the environment. These are your yield advantages. A new and unique cooling concept inside the inverters also guarantees an even distribution of heat and therefore a long service life for the units.

The advantage of three-phase feed-in is that the solar power produced is always distributed symmetrically on all three grid conductors to the public grid. This is the case with these inverters over the entire power range. When planning the system, this eliminates the need to avoid an asymmetry of more than 4.6 kW, which is sometimes time-consuming, by selecting individual inverters accordingly. Symmetrical feed-in is entirely in the interest of the energy supply companies. That makes lengthy discussions with these companies a thing of the past.

Smart Energy Manager for coolcept, coolcept-x, coolcept³, coolcept³-x, StecaGrid 8000+ 3ph and 10000+ 3ph. The feed-in management solution: The StecaGrid SEM offers different options of realising feed-in management with a photovoltaic system. A ripple control receiver from the relevant distribution grid operator can be connected. The feed output at the grid connection point can be limited to an adjustable value, or the ripple control signal can be switched to the relay output. Up to ten inverters can be connected to the StecaGrid SEM via the RS 485 interface.
