COOLCEPT FLEX | 2 MPP TRACKER
Reliable technology – even more versatile
With coolcept fleX, KATEK Memmingen presents the successor generation to Steca's established coolcept topology. Coolcept fleX offers a creative energy concept for any modern home.
What is coolcept fleX?
The all-new electronic platform is being used as the technological heart of the next generation of solar electronics and connects photovoltaic-based power generation, load management and even e-mobility for the very first time. The coolcept fleX platform is open about its future use, it is always implemented on a single card. This extremely small and compact format allows the use of affordable standard components on the printed circuit board. Thus, it is possible to use the same device
for various different applications.
Coolcept fleX inverter
Coolcept fleX is the centerpiece of the new generation of inverters.
As usual, with rated powers of 1.5 to 5.0 kW, they achieve particularly high peak efficiencies.
The advantages of coolcept flex inverters
Coolcept fleX is flexible.
Several MPP trackers allow you to manage simple or even complicated module fields.
Coolcept fleX is robust and simple.
Indoor and outdoor installation is made possible by a robust IP65 housing. However, the product range is not only one of the lightest in its class, but it is also very easy to install.
Coolcept fleX is scalable.
KATEK Memmingen offers an integrated and scalable concept for the production, consumption, storage and supply of energy for the modern home of tomorrow.
WORLD PREMIERE
One for all
This all-in-one solution at an incomparable price offers functions for very different applications and is even scalable depending on the power required. Whether you need one or more MPP trackers, high or low voltage storage, a solution with or without backup power, anything is possible. KATEK Memmingen has already thought of and prepared the charging of an electric vehicle directly from a PV generator. The new components and adjustment options allow use in many countries.
Maximum efficiency at all input voltages and reliable cooling concept
The maximum efficiencies of the topology of the state-of-the-art power electronics guarantee minimal losses, thus guaranteeing a very long service life thanks to extremely low self-heating levels.
