Installation instructions Powador 3200 / 4400 / 5300 / 5500 / 6600_EN
A summary of the components:
DC terminal point:
Two generator strings are connected in parallel either at a DC terminal point between the PV array and the inverter or directly on the
inverter (terminals for three strings are provided on the inverter). Of course, you can also connect the strings directly to the PV array and
then run just one negative and one positive lead to the inverter.
DC disconnect:
In order to be able to disconnect the inverter on the generator side from sources of voltage, the inverter comes equipped with an integrated
DC disconnect. As a result, the installation of an external DC disconnect is not required.
Line fuses:
For grid-side fuse protection of the Powador 3200 / 4400 / 5300 / 5500 / 6600, the largest fusing allowed is a B35 automatic circuit
breaker, even if the cross-section of the cable that has been laid would allow a larger fusing. (5.3: Electrical connection – grid connection).
We recommend the following conductor cross-sections for cable lengths up to 20 m:
– Powador 3200/4400
2.5 mm
2
– Powador 5300
4.0 mm
2
– Powador 5500/6600
6.0 mm²
Larger cross-sections should be used for longer leads. The maximum clamping range of the cable fi tting is 21 mm.
In accordance with VDE 0100 part 430, “Protection of cables and lines against overcurrent”, NYM cables with fi xed wiring should be
protected as follows:
Installation type B2 (multi-conductor lead in pipe or duct, either on or in walls or fl ush-mounted) at an ambient temperature of +25°C.

Feed-in meter:
The required feed-in meter is specifi ed and installed by the responsible power supply company. Some power supply companies also allow
the installation of your own calibrated meters. In this case, you do not need to pay rent for the meter, but the power supply company may
require that the meter be periodically calibrated.
Selective main switch:
Contact your power supply company if you have questions concerning the required main switch.
