Electrical Connection SMA Solar Technology AG Connecting the Battery Current Sensor: Use cables of intrinsically safe circuits Always use cables of intrinsically safe circuits for the connection of battery current sensors. "Intrinsically safe" means here that the cable is double-insulated and that the wire melts but the insulation remains intact in the event of a short circuit. In addition, the cable is not combustible. In order to avoid measuring errors, make sure to use twisted cables. Installation notice The battery current sensor must be looped around the negative pole of the battery. In addition, the contact of that battery current sensor, which is connected to the Sunny Island (1), must be connected to the terminal "BatCur+" (see following figure). • Positive battery current means that the battery is discharging (current from the battery) • Negative battery current means that the battery is charging (current into the battery) 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 cables correspondingly to the "BatCur" connection of the 4-pole print terminal included in the delivery. 4. Tighten the terminals. 5. Insert the 4-pole print terminal into the "BatCur" socket on the Sunny Island. ☑ The battery current sensor is installed. 42 SI5048-TB-TEN110340 Technical Description
SMA Solar Technology AG Electrical Connection Commissioning the battery current sensor When connecting a battery current sensor to the Sunny Island, the device's internal offset must be adjusted during the first commissioning of the off-grid system. To do this, proceed as described in section 8.3 ”Commissioning the Battery Current Sensor” (page 60). 6.4.3 Communication for Multi-device Connection The Sunny Island can be connected in parallel or in a three-phase system with other Sunny Island in order to increase the overall power. The Sunny Island inverters communicate with each other via an RJ45 communication cable. A black RJ45 cable is provided with each Sunny Island. You need it in order to establish an (internal) communication between several Sunny Island inverters. The communication bus's maximum total length may not exceed 30 m. If you operate only one Sunny Island in your system, the cable is not required. Proceed as follows to implement the connection: 1. Remove one of the two plugs in the rubber connection area. 2. Lead the RJ45 cable from the outside through the plugs inside the Sunny Island master. 3. Remove the termination resistor plugged into the master's "ComSyncOut" socket and insert it in the master's "ComSyncIn" socket. 4. Plug the RJ45 cable into the "ComSyncOut" socket. 5. Connect the Sunny Island master to the slave: Number of slaves Connection procedure 1 Slave • Take the RJ45 cable coming from the master, insert it into the Sunny Island slave and plug it into the "ComSyncIn" socket. • Leave the termination resistor plugged into the "ComSyncOut" socket. ☑ The Sunny Island master and Sunny Island slave are connected.

Commissioning the battery current sensor<br />
When connecting a battery current sensor to the <strong>Sun</strong>ny Island, the device's internal offset<br />
must be adjusted during the first commissioning of the off-grid system. To do this, proceed<br />
as described in section 8.3 ”Commissioning the Battery Current Sensor” (page 60).<br />
6.4.3 Communication for Multi-device Connection<br />
The <strong>Sun</strong>ny Island can be connected in parallel or in a three-phase system with other <strong>Sun</strong>ny Island in<br />
order to increase the overall power. The <strong>Sun</strong>ny Island inverters communicate with each other via an<br />
RJ45 communication cable. A black RJ45 cable is provided with each <strong>Sun</strong>ny Island. You need it in<br />
order to establish an (internal) communication between several <strong>Sun</strong>ny Island inverters. The<br />

5. Connect the <strong>Sun</strong>ny Island master to the slave:<br />
Number of slaves Connection procedure<br />
1 Slave • Take the RJ45 cable coming from the master, insert it into the<br />
<strong>Sun</strong>ny Island slave and plug it into the "ComSyncIn" socket.<br />
• Leave the termination resistor plugged into the "ComSyncOut"<br />
socket.<br />
