Proceed as follows when installing the battery current 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.
The battery current sensor must be looped around the negative pole of the battery.
In doing so, the side of the shunt that is connected to the Sunny Island 5048 must
be connected to the "I_Bat+" connection terminal.
If the battery current sensor is connected as described above,
• positive battery current means that the battery is discharging (power from
the battery)
• negative battery current means that the battery is charging (power into the
battery)
