6.5 Connecting the DC Cable
The DC- / inverter cabinet contains optional high and low voltage fuses. They allow the string
distribution boxes (e.g. Sunny Main Box) to be connected. All Sunny Centrals are equipped with one
busbar per potential as standard.
Protected inputs on the Sunny Central
The Sunny Central has protected inputs on the DC side. The number depends on the device
type. The number of DC inputs in the various Sunny Centrals is specified in the Technical
Data.
NOTICE!
Insufficient voltage resistance of the DC connection cable can cause short circuits
which damage the Sunny Central.
• Use only DC cables which are sufficiently voltage-resistant.
