Powerwall 3 in UK: grid charging drops from 10 kW to 7.7 kW, per user
Unconfirmed: a UK user with a Powerwall 3 and three expansion batteries says the system charged from the grid at 10 kW since its installation in June, which they did not expect. According to the post, they read that an update had allowed that rate for other users. On September 22, grid charging was limited to 7.7 kW. The user asks what determines whether the Powerwall switches between 7.7 kW and 10 kW, and notes that 10 kW let them use the bonus charging slots of Intelligent Octopus Go (IOG), which would also fill the battery.…
- Powerwall 3 with expansions dropped from 10 kW to 7.7 kW on September 22.
- Per the user, the grid import limit changed with no identified cause.
- The user links the 10 kW rate to an update reportedly seen by other owners.
🔎 Why it matters: No official confirmation: the user reports that their Powerwall 3 dropped from 10 kW to 7.7 kW of grid import on September 22, without citing a software version.
📈 Upside: Per the user, 10 kW allowed the battery to fill during IOG's bonus charging slots.
📉 Risk: If the 7.7 kW limit persists, the battery could fail to fill during those bonus slots, according to the user's account.
