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 Sunny Central is suitable for outdoor installation provided that the specified safety distances are maintained.
The Sunny Central for station installation is suitable exclusively for indoor installation provided that the specified safety
distances are maintained. The enclosure conforms with degree of protection IP54. The Sunny Central is classified under
Class 4C2 according to EN 60721-3-4 and is suitable for operation in a chemically active environment.
The maximum permissible DC input voltage of the Sunny Central must not be exceeded.
The Sunny Central 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 Sunny Central. The maximum AC voltages to ground are as
follows:
• For inverter type SC 500CP-JP, voltages of max. ±800 V to ground.
• For inverter types SC 630CP-JP und SC800CP-JP, voltages of max. ±1,450 V to ground.
