7.2 Plant Time
7.2.1 Information on Plant Time
The date and time of a PV plant is referred to as plant time.
When operating your Bluetooth PV plant with the Sunny WebBox, all connected Bluetooth devices
adopt the plant time of the Sunny WebBox.
If additional communication products (e.g. Sunny Beam with Bluetooth or Sunny Explorer) are added
to the PV plant, the new communication products automatically adopt the existing PV plant time.
If you change the plant time, all the inverters will adapt immediately to the new plant time. Additional
communication products in the plant only adopt the plant time after some time (max. 7 hours later).
The plant time can be manually adjusted in the Sunny WebBox or synchronised via the Internet.
With "Automatic time synchronization", the Sunny WebBox synchronises the date and time with
Sunny Portal once a day. You do not need to register in Sunny Portal to do this.
7.2.2 Setting the Date and Time
