Coolcept Flex StecaGrid 5011_2 inverter


Proven technology - even more flexible

With coolcept fleX, KATEK Memmingen presents the next generation of the proven coolcept topology. Coolcept fleX offers a creative energy concept for every modern home.


What is coolcept fleX?

The all-new electronic platform will be used as the technological heart of the next generation of solar electronics, combining power generation from photovoltaics, load management and even e-mobility. The coolcept fleX platform is open in its future application, but still made on a single card. It is now possible to use a single device for very different applications.


Coolcept fleX inverter

Coolcept fleX is the heart of Steca's new generation of inverters.
With rated outputs of 1.5 to 5.0 kW, they achieve the usual high peak efficiencies.


Your advantages of coolcept fleX inverters

coolcept fleX is flexible.
Several MPP trackers allow you to manage simple or even complex module fields.


Coolcept fleX is robust and simple.

Indoor and outdoor installation is made possible by a rugged IP64 housing. Nevertheless, with less than 14 kg, the product range remains not only one of the lightest in its class, but also simple to assemble as usual.


Coolcept fleX is future-proof.

Steca offers the global concept for the production, consumption, storage and supply of energy for the home of tomorrow.



One for all
This incomparably low-cost all-in-one solution offers functions for very different applications and is even scalable in terms of power requirements: whether it's one or more MPP trackers, high-voltage or low-voltage memory, with or without backup power - anything is possible. Even charging an electric vehicle directly from a PV generator is already thought out and prepared. The new components and tuning options also allow use in the following applications
especially in many countries.


Maximum efficiency at each input voltage and proven cooling concept

The highest efficiencies of the latest power electronic topology guarantee minimal losses and therefore a very long service life thanks to minimal self-heating.
