I've got a powerwall 2 installed at the end of September and I'm very happy about it.
When it was installed it has been upgraded to 1.6.0. At the moment, surfing the forum, I can understand that the current firmware version is 1.9.1. So I've tryed to update it via wizard but the update fails.
The error it gives is: unable to update, try refreshing the page. But after refresh as suggested, the error still there.
I've tryed with Chrome and Edge, both via ethernet and via direct wifi (TEG...).
Any idea how to succed with the update?
