Voltwerk VC WL 110
Central Inverter
- European efficiency factor of 97.0 % guarantees maximum yields
- Maximum availability thanks to overdimensioning of critical components
- Module wiring with very long strings due to maximum input voltage of 965 V
- Easy installation and service due to generous and clear layout
Immediately usable in whole Europe
An especially configured EU type in all power categories is available for the European market. In order to comply with both the German medium voltage directive and the German Renewable Energy Law, a specially configured type is available as well.
Maximum yields
With a maximum efficiency factor of 97.6 % the Voltwerk VC WL 110 is among the front runners in his class. The very high efficiency factor is et al. achieved by the use of the latest transistors with trench gate structure. Thanks to the fast and precise MPP tracking the Voltwerk VC WL central inverters are able to extract maximum power from the PV generator under all weather conditions.
Highest availability
In respect of the operational life span of the inverter, the layout of the technical parameters has been optimised. The trench IGBTs (Insulated Gate Bipolar Transistors) used in central inverters have crucial advantages compared to conventional IGBTs:
- optimised characteristic curve
- lower losses
- greater robustness
- gentler switching behaviour
This results in improved EMC and temperature behaviour of the Voltwerk VC WL central inverters and a higher technical availability. The intelligent recognition of the minimum output preserves the AC contactor. A fast current surge detection protects the trnsistors.
Flexible dimensioning of PV systems
The high input voltage of maximal 965 V of the inverter VC WL 110 allows for efficient module wiring and very long module strings. Thus wiring expenses decrease significantly.
Installation and maintenance friendly
The clear layout of the devices permits simple connection of the power cables and fast installation. The overall height of the Voltwerk VC WL central inverter of only 180 cm not only permits transport through normal structural doors, but also problem-free setup in every concrete compact station. In addition, the stand space is very small. Neither assembly nor adjustment of the central inverters after installation are necessary.
