Kaco Powador 00 Series
The Powador 3200 – 5500 without transformers can be single-phase connected individually, due to their nominal output.
Kaco Powador 00 Series
The single-phase Powador 6600 – 9600 have a nominal output of more than 5ákW; for this reason the unbalanced load between feed-in phases should be considered during the dimensioning.

Kaco Powador 00 Series
Inverters without transformers

Higher efficiency
Without transformers, the inverters of the Kaco 00 series achieve optimal efficiency. As a specialist for inverters without transformers, Kaco has equipped all devices of the 00 series with a full bridge and omitted the boost converters. The self-controlled devices emulate the sinus voltage curve of the public power grid using a H4 bridge. Prerequisite for using the 00 series inverters is an input voltage higher than the grid peak voltage.
Simple installation
With a MPP range of 350 to 600 V and an off-load voltage of 800 V the conditions for a simple system dimensioning are ideal. The devices are connected to the grid by screw terminals. The redundant 3-phase monitoring, including an AC/DC sensitive residual-current-operated protective device, facilitates the grid connection, even in the case of systems with several inverters.
Long service life
All inverters operate up to outputs of 8 kW with silent and purely passive cooling. The lost heat is optimally dissipated by the cooling element on the back. This cooling without mechanical fans reduces error sources and thus achieves a long life-cycle of the devices.
100 % feed-in
The Kaco Powador 7900 was specifically developed for applications with connections limits of 20ákW. Due to the 100á% symmetrical feed-in of 20ákW, not one watt of power is wasted, not even in Spain, Italy or Greece.
