Battery Current Sensor - SMA Sunny Island 5048 Installation Instructions Manual

Electrical Connection
Proceed as follows when installing the battery temperature sensor:
1. Pierce a hole in the rubber terminal area at the corresponding position.
2. Starting from the outside, feed the cable with cable end sleeves through the hole.
3. Insert one wire with the cable end sleeves in each of the "T_Bat" connection
terminals of the provided 4-pole print terminals and tighten the screws of these
terminals.
4. Insert the 4-pole print terminal into the corresponding (upper) socket.
Fasten the battery temperature sensor to the outside of one of the battery cells.
Choose a cell in the middle of the battery bank, the batteries generate the most
heat in this region during operation.

6.4.2 Battery Current Sensor

In addition to internally measuring the current, the battery current can also be measured
using a shunt.
The battery current sensor is absolutely necessary if DC generators and
DC loads are to be connected. Only one battery current sensor, which is
connected to the corresponding master, is required for a cluster.
The current sensor type is set using the "#225.01 BatCurSnsTyp" parameter and the
respective measuring range can be set using the "#225.02 BatCurGain60" or
"#225.03 BatCurGain50" parameter.
