G3 hybrid firmware

The battery auto updated to 3015 a couple days ago automagically and so I took the plunge to press UPDATE on the inverter taking me from D0.305-A0.305 to D0.307-A0.307.

It went without a hitch in 15 minutes and the UPDATE button has gone.

But the support site says there is more updates? Do I need to do something else to get to v309?

if you want to go to the very latest versions then only the helpdesk can do it… 307 can be done by the web portal but anything else the helpdesk do
