Table 10- 3 Technical specifications of the 120 kW device
Rated DC voltage V 600
Rated DC current A 200
Operating voltage range V 0 ... 1000 Applicable for side 1 and side 2
Remark: In stepping-up operation, the voltage can be
increased as maximum by a factor of 8.
Overvoltage range V 800 ... 920 Applies for side 1 and side 2:
operation is possible in this range with reduced cur-
rent.
Starting at 800 V, the maximum current reduces down
920 ... 1000 Applies for side 1 and side 2:
after switching on and off, voltages are only permissi-
ble in this range for 30 s.
DC system voltage V 1000 According to IEC 62109-1 (PV and battery circuits)
AC system voltage V 600 According to IEC 61800-5-1
Recurring peak voltage V 1000 between the DC line connections (P1, N1, P2, N2) and
housing / ground (according to EN 60664-1: 2007)
In the voltage range 0 V … 600 V
In the voltage range 600 V … 800 V
Inductance of the energy storage
µH 500 per power unit
Monitoring For voltages exceeding 1050 V and for currents ex-
ceeding 3 x 180 A = 540 A, the device is shut down as
a result of the hardware-based monitoring function.
The device can generate a maximum short-circuit
DC electronics power supply V 24 Permissible voltage range: 18 … 30 V
Current consumption: 20 A at 24 V
Degree of protection IP00 Degree of protection applies in delivery condition. The
power unit connections protrude from the enclosure.
The degree of protection IP20 is easy to achieve if the
power unit connections are covered on the cabinet
side.
The following applies to applications in Australia:
The enclosure of the device does not meet the re-
quirements of a fire enclosure. Therefore, the device
must be installed in a suitable enclosure to meet the
application and site requirements.
