Technical Description

6.4.2 Battery Current Sensor

In addition to the internal measurement, the Sunny Island provides the possibility to measure the 
battery current via a shunt. You need this function if you intend to operate additional DC generators 
and DC loads in your off-grid power system. In a cluster, only one battery current sensor is needed; it 
is connected to the master of the cluster.

Example:

Connecting the Battery Current Sensor

NOTICE

Destruction of the battery due to the connection of additional DC devices.
If additional DC devices are installed in an off‑grid system, the internal Sunny Island current 
measurement becomes inaccurate. The charge current can no longer be set exactly and as 
a result will destroy the battery.

• Install an external battery current sensor (shunt).
