firmware, download and load configurations, and download data.
The SUN2000 can communicate with the SUN2000 app over a Bluetooth module or
USB data cable connected to the USB port, so that you can view the operating
information and set parameters over the app.
 The SUN2000 app (Android) can communicate with the SUN2000 over a Bluetooth module or USB
data cable, whereas the SUN2000 app (iOS) supports the communication with the SUN2000 only
over a Bluetooth module. For details about version mappings and the operations on the SUN2000
app, see the SUN2000 APP User Manual.

Use the USB port only during maintenance (such as power-on setting, upgrade, and data export).
Ensure that the USB cover is tightened when the USB port is not in use.
If only one SUN2000 is used, connect a communications cable with waterproof RJ45
connectors to either of the two RS485 ports and block the other one with a waterproof
cover.
If multiple SUN2000s are used, connect all SUN2000s in daisy chain mode over the
RS485 communications cable.
Connect the SUN2000 to the SmartLogger to implement data collection and monitoring,
