Commissioning the Battery Current Sensor in Off-Grid Systems

To operate the battery current sensor, you must set the type of the battery current sensor and start the
adjustments of the battery current sensor.
The Sunny Island distinguishes between battery current sensors of the types 50 mV and 60 mV. The types reflect the
amplification factor of the battery current sensor. The amplification factors are given in amperes per 50 mV or in
amperes per 60 mV, e.g., 400 A/60 mV.
Requirement:
☐ The Sunny Remote Control must be connected to the master.
