Less is More: No Transformer, lots of Power.
The Powador 3200 – 9600 transformerless string inverters.
Our Powador 3200 to 9600 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. We have changed the
product names. 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 sineshaped
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 heatsink on the rear
of the unit. The rest of the heat is radiated
from the surface of the aluminium
housing. No fans, no problems, just long
service life.
