Single-phase inverter with one MPP tracker
Proven technology – even more flexible
With coolcept fleX, Steca presents the next generation of its proven coolcept topology. coolcept fleX offers a creative energy concept for every modern home.
What is coolcept fleX?
A brand-new electronics platform is the technological core of the next generation of solar electronics, combining PV electricity, load management and even e-mobility. Although the coolcept fleX platform is open for future use, it is still built on a single circuit board. This means the same device can now be used for very different applications.
coolcept fleX inverters
coolcept fleX is the core of Steca’s new generation of inverters.
Rated outputs of 1.5–5.0 kW achieve the usual high peak efficiencies.
Benefits of using coolcept fleX inverters coolcept fleX is flexible.
Several MPP trackers can handle simple or even complex module arrays.
coolcept fleX is robust and uncomplicated.
The durable IP65 enclosure allows indoor and outdoor installation. The range is still one of the lightest in its class and easy to install.
coolcept fleX is future-proof.
Kontron Solar GmbH offers a complete concept for energy production, consumption, storage and feed-in for the homes of the future.
WORLDWIDE INNOVATION
One for all
This complete solution is unmatched in price, offers functions for many applications and is even scalable in power: whether you need one or more MPP trackers, high- or low-voltage storage, or a solution with or without backup power – everything is possible. Even charging an electric car directly from the PV generator has already been planned for. New components and setting options also allow use in many countries.
Highest efficiency at any input voltage and a proven cooling concept
The maximum efficiencies of modern power electronics topology ensure minimal losses and a very long service life thanks to very low self-heating.
