SUNNY ISLAND 5048 - Technical Description - Wind & Sun Ltd.

Electrical Connection SMA Solar Technology AG
Generator start
The Sunny Island can control generators. The Sunny Island directly supports generators that can be
started and 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
from SMA Solar Technology.
Default setting of the relays
Relay 1 is preset to the "AutoGn" generator start function and relay 2 to the "AutoLodSoc"
load shedding function.
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
tripping threshold is higher than 0.6 A.
This connection can be used, for example, to supply a DC contactor for load shedding.
For connection, proceed as follows:
1. Pierce a hole in the rubber connection area at the corresponding position.
2. Starting from the outside, lead the insulated conductors with bootlace ferrules through the hole
in the Sunny Island.
3. Connect the wires correspondingly to the "BatVtgOut" terminal 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.
