equipped as standard with an integrated irradiation sensor and an external module temperature
sensor. The Sunny SensorBox delivers the sensor data via an RS485 interface to the SMA

Power Metering (not for Sunny Central 500HE-US)
The Shark power meter and iLon device are a revenue grade metering system. They allow the output
generation of the inverter to be monitored and recorded. This information is sent via the internet to a
network that can process the data into a utility bill.
