As tile said we had a power outage for 7 hours yesterday while the local utility did pole replacement. Powerwalls were flawless, and many neighbors were surprised when I plugged my Leaf in to take advantage of the excess solar that would have gone to waste since the grid couldn't take it. Powerwall cycled from discharging to charging all day.
Today was a little surprised that the battery only charged to 85% then started feeding the grid. Is this a protective measure, or did something happen? Anyone with similar experiences?
