2.1 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.

• For the inverter types SC 500CP XT/630CP XT/720CP XT/760CP XT/800CP XT, voltages can reach a maximum of ±1,450 V to ground.

• For the inverter types SC 850CP XT/900CP XT/SC 1000CP XT, voltages can reach a maximum of ±1,600 V to ground.

• 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 Series CP XT and CP-JP and for SUNNY CENTRAL STORAGE".

Do not deactivate or adjust settings that affect grid management services without first obtaining approval from the grid operator.
