Efficiency factor and reliability
The optimum adjustment of electronic control unit, applied materials and components permit an extremely high efficiency factor even at lowest input powers. With a maximum system efficiency factor of 98.7 % (European efficiency factor 98.5 %) the VC inverters are the most efficient ones in their class. By use of aging resistant film capacitors and generously laid-out threshold values for the specification of the individual components this series also guarantees highest reliability.
High ease of use
The integrated VGA touch display with intuitive navigation allows the immediate display of the current operating status and a comfortable adjustment of grid and control values. The integrated webserver enables easy access to the central inverter via Internet. For the connection of further monitoring systems a CAN bus is available.
Low installation costs
The novel concept of the VC series supersedes the assignment of combiner boxes, as DC circuit breakers are already integrated into the device. This leads to cost savings and a reduced planning and installation effort. The VC series comes with an integrated earthing kit including pre-fuses for the use of thin film modules. The ground fault monitoring both for positive and negative earthing is performed by the inverter control. Positive or negative earthing is monitored by the inverter control.
Safety First
In addition to high reliability and best efficiency factors the security of both the operating personnel and the power plant are top priorities. Therefore all Voltwerk products bear the GS-seal and are certified by Bureau Veritas. However, if critical situations should arise, these are detected and terminated at an early stage by different tracing algorithms. One example is the disconnection of the DC input at
high input voltages.
