Yes, though the path has changed recently. Until recently the Powerwall 2 wasn’t compatible with the Powerwall 3 or its Expansion Packs, which left owners with no Tesla-approved way to expand.

The recommended path now, for most Powerwall 2 owners wanting more capacity, is to add a Powerwall 3 alongside the existing system, with Expansion Packs if you need additional storage.

Removing the Powerwall 2 and switching to a different battery system generally isn’t recommended, because it means writing off a functioning asset.
