Check the network settings of all components, including the router, Sunny WebBox, and computer, and replace any defective network parts. Perform a connection test to diagnose network issues.

Why does Sunny Portal contain two plants with the same name after a SMA Measuring Instruments Sunny WebBox replacement?
This issue occurs due to double Sunny Portal registration. The replacement Sunny WebBox logs into Sunny Portal with a new plant identifier, causing Sunny Portal to create a new plant, even if the name is the same. Assign the plant ID of the old plant to the replacement device. Enter the e-mail address of a user who has administrator rights for the plant in Sunny Portal in the replacement device. Delete the new plant the replacement device created in Sunny Portal.
