If you perform Step 2 before Step 1, the SUN2000 reports a fault about abnormal shutdown.
The SUN2000 can start normally after the fault is automatically rectified. The default alarm
clearance time is 1 minute. You can modify the time over the NMS software installed on the
PC that connects to the SUN2000.
Step 2 Turn on the DC switches at the bottom of the inverter chassis.
Step 3 (Optional) Measure the temperatures at the joints between DC terminals and connectors using
a point-test thermometer.
To ensure that the DC terminals are in good contact, check the temperatures at the joints
between DC terminals and connectors after the SUN2000 has been running for a period of
time. Ensure that the temperature rise does not exceed 40°C.
Step 4 Connect the SUN2000 to the mobile phone that runs SUN2000 app (app for short) through a
Bluetooth module or USB data cable.
Mobile phone operating system: Android 4.0 or later, and iOS 7.0 or later. When the iOS is
used, the app supports only Bluetooth connection.
When you use a Bluetooth module to set up the connection, ensure that the mobile phone
and inverter are at most 5 meters away from each other. Otherwise, the communication
quality between them will deteriorate.

Figure 6-1 Bluetooth module connection mode
Purchase the Bluetooth module bundled with the SUN2000. A Bluetooth module purchased from any
other source may not support communication between the SUN2000 and the app.
The Android system supports the Bluetooth module USB-Adapter2000-B and BF4030.
The iOS system supports the Bluetooth module USB-Adapter2000-B.
