8.2 Performing a Piggy-Back Update

Piggy-Back updates are performed via Sunny Explorer. There is no need to replace the Piggy-Back.
Existing inverter settings and data are retained after the update. Only carry out an update providing
that the feed-in power of the inverter is sufficient (at least 50 W). After a successful update, restart
Sunny Explorer.
