It Grid - VOLTWERK VC 200 Instrucciones De Servicio

Rotary field
4.3.4
Transformerless central inverter
Short-circuit proof
|
Voltage resistance of at least 1000 V
|
No consumer may be connected to the AC output voltage of the
|
device. Consumers can override the IT grid or influence the regulation
of the central inverter. It is permissible to connect a galvanically
isolated transformer for the auxiliary power supply of the inverter.
Use aluminium or plastic cable clips to act as cable strain relief.
|
Two AC cables can be connected per phase.
The AC output voltage is 300 V
performance 200 kVA and 300 kVA, and for the level of performance
350 kVA, it is 315 V (phase to phase). Please note:
eff
Transformerless central inverters have higher currents than devices
|
with transformers.
The central inverters switch on with a clockwise and an anti-clockwise
rotary field. Use clockwise rotary fields where possible.
Auxiliary power supply
Single-phase cable
|
230 V -10%, +15% (according to EN 50160)
|
50 Hz
|
TN grid (L1, N, PE)
|
Necessary (external) fuse: 16 A, type B or similar.
|
If there is no auxiliary power supply (230 V
|
galvanically isolated transformers with 2.5 kVA output to supply the
central inverter with 230 V.
The auxiliary power supply is used to supply the display, the LED
indicators, the internal fans and the electronics of the central inverter.

IT grid

Material damage due to modified IT grid!
An unavailable IT grid may damage the solar generator and/or the central
inverter. The reliability of the IT grid must be guaranteed with insulation
and earth fault monitoring on an earthed solar generator.
