StecaGrid 2020

Highest efficiency with a long service life


The very high efficiency level results in a peak efficiency of 97.5% and a European efficiency level of up to 96.7%, 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.

Product design and visualisation

The StecaGrid has a graphical LCD display that visualises energy yield values, current outputs and the operating parameters of the system. The innovative menu offers the possibility of an individual selection of the different measured values.

Thanks to a guided, pre-programmed menu, the seamless, final commissioning of the unit takes place.


Weighing just 9 kg, the lightweight units can be mounted effortlessly and securely onto the wall. The wall bracket supplied and the practical recessed grips for right- and left-handed use make for easy and very comfortable installation. It is also not necessary to open the unit for installation. All connections as well as the DC isolator are accessible from the outside.

The inverters of the coolcept-120 series meet all of the requirements for use in countries with 110 V, 120 V and 127 V grids. The units are the ideal solution for markets such as South America, Africa and Asia.
