The cumulative number of global installations of the Powerwall home energy storage systems has reached 250,000 according to Tesla's recent tweet.

That's another huge milestone. For reference, the company has sold over 2 million electric cars so far and counting.

Combining the news with the previous info about 200,000 Powerwall in May 2021, we can estimate that the company has added some 50,000 units over about 6 months or so. The average installation rate would be then probably at roughly 8,000 per month.

The company currently offers two versions of the 13.5 kWh Powerwall - the Powerwall and a more powerful Powerwall+ version for solar installations and with a higher power output, shown below:

 

The combined capacity of 250,000 Powerwalls would be some 3.4 GWh (actually noticeably less, as initially there were versions with different battery capacity, like 7 kWh or 10 kWh).
