SMA Solar Technology AG Electrical Connection
Technical Description SI5048-TEN093630 47
Generator Start
The Sunny Island can control generators. The Suny Island directly supports generators that can be
started/stopped using a single contact. Generators which require more than one contact must be
connected to the Sunny Island via a Generator Manager (GenMan). This product can be acquired
through SMA Solar Technology.
6.4.5 BatVtgOut Power Supply
The battery voltage is conducted to the outside at these terminals. The battery voltage is fused at both
poles by PTC resistors (max. 0.6 A). Depending on the internal temperature of the Sunny Island, the
triggering threshold is at over 0.6 A.
This connection can be used, for example, to supply a DC contactor for load shedding.
For connection, proceed as follows:
1. Poke through the appropriate place in the cable insert with a pointed object.
2. Starting from the outside, feed the cable with cable end sleeves through the hole in the
Sunny Island.
3. Connect the cables correspondingly to the "BatVtgOut" connection of the 4-pole print terminal
included in the delivery.
4. Tighten the terminals.
5. Insert the 4-pole print terminal into the "BatVtgOut" socket on the Sunny Island.
Default setting of the relays
By default, relay 1 is set to the generator start function "AutoGn" and relay 2 is set to the
load shed function "AutoLodSoc".
