Connecting Multiple Inverters to the SmartLogger
This topic describes how to connect the SmartLogger to multiple inverters.
The SmartLogger can connect to multiple inverters through
a daisy chain, as shown in Figure 4-21.

- A maximum of 80 devices can be connected to one SmartLogger. You are advised to connect fewer than 30 devices to each RS485 route.
- The addresses for all devices in the daisy chain should be within the searching scope set in the SmartLogger and they must differ from each other. Otherwise, the communications would fail between the device and the SmartLogger.
- If the firmware version of the SUN2000 is V100R001C00SPC010 or later, or V100R001C81SPC105 or later, you can perform Auto Assign Address on the SmartLogger. If detecting that an RS485 address is repeatedly used, the SmartLogger automatically allocates another address and hence no local operation is required.
- Baud rate of all the devices in one daisy chain should stay consistent with those of the SmartLogger.
