STECA COOLCEPT FLEX
Coolcept fleX offers an complette inverters family of grid conneciton inverters for the actual home.
What is coolcept?
Coolcept is Steca‘s new inverter topology that provides the highest peak efficiency. It is basically characterised by circuit simplicity combined with highest efficiency. The patented coolcept topology is a global innovation that is only available from Steca.
The advantages of coolcept
Coolcept is cool.
High peak efficiency means the lowest possible heat dissipation. This makes cooling elements unnecessary.
Coolcept is efficient.
Stable peak efficiency over the entire power range ensures maximum yields.
Coolcept is long-living.
Low heat dissipation and cool components guarantee a long service life.
This incomparably affordable all-in one solution offers functions for very different applications and is even scalable in relation to the power requirement. Whether you need one or more MPP trackers, high-voltage or low-voltage storage, or a solution with or without an emergency power supply – everything is possible. Steca has already thought of and prepared for charging an electric vehicle straight from a PV generator. The new components and setting options enable the use in many countries.
Maximum efficiencies at all input voltages and reliable 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.
