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. The maximum AC voltages to ground are as
follows:
• For the Sunny Central 500CP-JP, the maximum voltage to ground is: ±800 V.
• For the Sunny Central 630CP-JP, the maximum voltage to ground is: ±1450 V.
• For the Sunny Central 800CP-JP, the maximum voltage to ground is: ±1450 V.
• For the Sunny Central 1000CP-JP, the maximum voltage to ground is: ±1600 V.
Do not switch off or adjust settings that affect grid management services without first obtaining approval from the grid
operator.
