Description:
Inverter KACO Powador 4400 INT
Powador 4400 transformerless string inverters
The Powador 4400 transformerless single-phase inverters are now equipped with digital controllers so that they can be used internationally. The appropriate country settings can easily be selected on-site; the country-specific settings are stored in the software, so the inverters can be quickly installed in any country. Users can also choose a menu language regardless of the selected country setting. The maximum PV generator power for which the particular unit is optimised can now be read from the designation.
All units operate with a full bridge without a step-up converter. Four IGBT power switches reproduce the sine-shaped voltage curve of the public power grid employing pulse width modulation. These are true single-stage, self-commutated units. However, the input voltage must be greater than the peak line voltage for them to be used. The units are equipped with a wide MPP range of 350 V to 600 V. The open circuit voltage is 800 V, which simplifies the work of installers when laying out systems. The same is true for the integrated DC disconnect. In addition, the units operate using purely passive noiseless convection cooling.
