Intended Use
The Sunny Central is a PV inverter which converts the direct current generated in the PV modules into grid-compliant
alternating current. An external MV transformer fitted downstream feeds the generated alternating current into the
utility grid.
The product is suitable for indoor and outdoor use.
The enclosure complies with degree of protection IP54. The inverter is classified under Class 4C2 as per
EN 60721-3-4 and is suitable for operation in a chemically active environment.
The maximum permissible DC input voltage of the inverter must not be exceeded.
The inverter must only be operated in conjunction with a suitable MV transformer.
• The MV transformer must be designed for voltages that arise during pulsed mode of the inverter.
• For the Sunny Central 500CP XT/630CP XT/720CP XT/760CP XT/800CP XT the maximum voltage to ground is:
±1450 V
• For the Sunny Central 850CP XT/900CP XT/1000CP XT the maximum voltage to ground is: ±1600 V
• Do not connect more than one inverter to one winding of the MV transformer.
• The neutral conductor on the low-voltage side of the MV transformer must not be grounded.
You can find further information on suitable transformers in the technical information "Requirements for Medium-
Voltage Transformers and Transformers for Internal Power Supply for the SUNNY CENTRAL".
Do not deactivate or modify settings that affect grid management services without first obtaining approval from the grid
operator.
