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.

The Steca PLI-300 is a cost-effective 300 W sine wave inverter that can be used to operate small AC loads. It has a manual on/off switch that can be used to switch the inverter off, avoiding self-consumption. The unit is particularly suitable for solar home systems in which small AC loads are manually switched on as required in addition to the DC loads. The unit is supplied with DC cables and has a European AC connection socket.

The Steca TR 0201 solar thermal controller offers everything your solar thermal system needs for safe and long-lasting system operation. The microprocessor-controlled regulator monitors and controls solar thermal systems with one collector array and one storage tank.

The Steca TR 0301 controller was the first controller on the market to fully visualise the operating status and solar circuit of a solar system via a graphically animated display.

Steca TF B001 is a particularly cost-effective fresh water controller for heating drinking water directly and hygienically using the instantaneous water heater principle for fresh water stations in the range of 0-20 l/min, 0-40 l/min and 0-80 l/min.
