Powerwall+ idle/unconnected for 2 years

[chhaprahiya]

I have a Powerwall+ that has sat idle/unconnected/never fully installed for 2 years.

How can I tell if it still retains charge?

Is it still good to connect to the PV system?

By connecting it to a TEG and hoping.

Sure, unless it has some other issue you’re not telling the group.
