6.1 Commissioning a Large-Scale PV Plant with Cluster Controller
Requirements:
☐ The cable must be connected to the communication terminal (see Section 5.3).
☐ The Piggy-Back must be installed in the inverter (see Section 5.4).
☐ Subject to the required network topology, the Cluster Controller must be connected to the
Speedwire network (see Cluster Controller installation manual).
Procedure:
1. Commission all inverters with installed Piggy-Back (see inverter installation manual).
2.
Deactivating the Webconnect function of the inverters
In a large-scale PV plant with Cluster Controller, communication with Sunny Portal takes
place via the Cluster Controller itself.
For optimal operation of large-scale PV plants with Cluster Controller, deactivate the
factory-activated Webconnect function of the inverter with installed Piggy-Back
(see Cluster Controller user manual).
