coolcept fleX | 1 MPP-Tracker

Single-phase inverter with one MPP tracker

Description

Proven technology - even more flexible

With coolcept fleX, Steca presents the successor generation of its proven coolcept topology. Coolcept fleX offers a creative energy concept for every modern home.

What is coolcept fleX?
The brand new electronic platform is used as the technological core of the next generation of solar electronics, combining power generation from photovoltaics, load management and even e-mobility. While the coolcept-fleX platform is open with regard to its future use, it is still implemented on a single circuit board. This means that it is now possible to use one and the same device for very different applications.

coolcept fleX inverters
Coolcept fleX is the core of the new generation of inverters from Steca.
With rated outputs of 1.5 - 5.0 kW, these achieve the usual high peak efficiencies.

Your advantages in using coolcept fleX inverters
coolcept fleX is flexible.
Multiple MPP trackers allow simple or even complicated module arrays to be handled.

coolcept fleX is robust and uncomplicated.
Indoor and outdoor installation is made possible by the robust IP65 housing. Yet the product range remains one of the lightest in its class and is also easy to install.

coolcept fleX is future-proof.
KATEK Memmingen offers the holistic concept for energy generation, consumption, storage and feed-in for the homes of tomorrow.

GLOBAL INNOVATION

One for all
This all-in-one solution is unmatched in price, offers functions for a wide range of applications, and is even scalable in terms of power requirements: Whether you need one or more MPP trackers, high-voltage or low-voltage storage, or a solution with or without an emergency power supply – anything is possible. Even charging an electric vehicle directly from a PV generator has already been considered and prepared. The new components and setting options also enable use in a large
number of countries.

Highest efficiency at any input voltage and proven cooling concept

The maximum efficiencies of the state-of-the-art power electronics topology ensure minimal losses, thus guaranteeing a very long service life thanks to extremely low levels of self-heating.
