Electrical Connection SMA Solar Technology AG 5.2.1 Connection of the AC Output Connection requirements of the grid operator Always observe the connection requirements of your grid operator! To connect the AC cable, proceed as follows: 1. Check the grid voltage. Complying with DIN VDE 0126-1-1, the Sunny Boy will not be fully operational if the grid voltage is constantly higher than 253 V. -
Page 19: Pv Generator Requirements
The unit has four DC plug connectors (two for each string) for connecting the PV generators. The connecting cables from the PV generators must also be fitted with this type of plug connector. The SMA order codes for the various connectors are as follows [see also section 12 ”Accessories” (page 39)]: •... -
Page 20: Pv String (Dc) Connection
Electrical Connection SMA Solar Technology AG 5.3.1 PV string (DC) connection DANGER! Danger to life due to high voltages on the Sunny Boy! • Before connecting the PV generator, ensure that the line circuit breaker is switched off. Use of Adaptors Adaptors (branch connectors) are not to be visible or freely accessible in the immediate surrounding of the Sunny Boy, in order that the DC circuit is not disrupted as a result. - Page 21 SMA Solar Technology AG Electrical Connection NOTICE! Exceeding the maximum input voltage can destroy the Sunny Boy! If the voltage of the PV modules exceeds the maximum input voltage of the Sunny Boy, it can be destroyed by the overvoltage. All warranty claims become void.
