Is it possible to read historical inverter data and send it to the Sunny Portal if a Sunny Home Manager is retrofitted?
(jh) If the Sunny Home Manager in the existing Sunny Portal system is replaced, the data of the existing system with all components remains intact. Only if components are explicitly deleted or if the PV system as a whole is deleted, is the data lost.
Retrofitting of an existing system (e.g. Webconnect) with a Sunny Home Manager is not possible. A new Sunny Portal system must be created with the Sunny Home Manager, in which the data of the components is recorded from this point onwards. The data in the previous system remains intact and can be viewed as history. It is not possible to transfer the data to the Sunny Home Manager system.
