SMA Solar Technology AG Connecting External Sources
Technical Description SI5048-TEN093630 103
14.1.1 Connection in Parallel
In the case of Sunny Islands connected in parallel which operate on the same phase and in the same
cluster, the internal transfer relay is activated simultaneously It is thus possible to multiply the generator
current and therefore to connect a larger generator or a higher grid current.
The maximal current in the system is limited to 150 A:
14.1.2 Generator Start Options
The Sunny Island supports the following options for starting the generator which can be set in standby
mode with the "234.07 GnStrMod" parameter:
•Manual
•Autostart
•GenMan
Number of Sunny Islands Maximum current
1 Sunny Island 56 A
2 Sunny Island 112 A
3 Sunny Island 150 A
Cable Length and Cable Cross-Section
Use the same cable lengths and cable cross-sections when installing the Sunny Islands with
the generator.
