User reports 208 V at home with 8.8 kW solar and Powerwall 3
Unconfirmed: A Reddit user reports that the installation of an 8.8 kW solar system with a Powerwall 3 stopped when they tried to connect it to the grid. During the connection, a low voltage warning appeared because the home's power measured 208 V. The electricians stopped work and the system was shut down. The home is a townhouse built in 2012, and the author suspects it has 208 V two-phase service, a configuration that, according to the author, exists in mixed commercial and residential areas.…
- 8.8 kW solar system with Powerwall 3 halted when connecting to the grid.
- Low voltage warning: the home measured 208 V, not 120/240 V.
🔎 Why it matters: There is no official confirmation: it is a user account claiming a 2012 home has 208 V two-phase service, while the Powerwall 3 system was designed for 120/240 V.
📈 Upside: The low voltage warning stopped the installation before the Powerwall 3 was connected to the grid.
📉 Risk: The 120/240 V design does not match the 208 V service the author reports, and the case is left without a documented solution.
