Efficient and durable
The successors of our Powador 2500xi to Powador 5000xi transformerless single-phase inverters are 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. We have changed the product names in line with this improvement. The maximum PV generator power for which the particular unit is optimised can now be read from the designation.
New product names
After the renaming the inverters are called as follows:
former Powador 2500xi now called Powador 3200
former Powador 3600xi now called Powador 4400
former Powador 4000xi now called Powador 5300
former Powador 4500xi now called Powador 5500
former Powador 5000xi now called Powador 6600
former Powador 4000 supreme now called Powador 5300 supreme
All units from the Powador 3200 to the Powador 6600 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. Screw terminals make connecting to the grid easy. The units contain a single- or three-phase monitoring system conforming to VDE0126-1-1, including an AC/DC-sensitive residual current protector. The units can thus be connected to the grid without any additional measures, even in installations with several inverters.
In addition, the units operate using purely passive noiseless convection cooling. The heat that is lost is, to a great degree, dissipated via the heat sink on the rear of the unit. The rest of the heat is radiated from the surface of the aluminium housing. No fans, no problems, long life.
Peak output made simple
The Powador 4000 supreme was designed with one goal in mind: The highest degree of efficiency and the highest yields. As a transformerless inverter, it already brings to the table the best possible prerequisites for reaching this goal. Its MPP range is from 350 V to 510 V and the no-load voltage is 600 V: That makes it an inverter for users who know exactly what they want.
With the standard setting, the Powador 4000 supreme works with a clock frequency of 18 kHz. For those who want to get even more from the unit, it operates in Power Boost Mode at a clock
frequency of 9 kHz via a jumper on the control circuit board. That reduces even further the already low switching losses of the power semiconductor and makes the degree of efficiency even higher.
