1Values provided for 25°C, at beginning of life. 3.3 kW charge/discharge power.
2Maximum continuous charge current/power is limited to 21.7 A / 5 kW when installed with Expansion units. A maximum continuous charge current/power of 34.8 A / 8 kW will be available with a future firmware version.
3The maximum number of Powerwall 3 units per installation may vary by market.
4Typical solar shifting use case.
5Cellular connectivity subject to network service coverage and signal strength.
Note
Powerwall 3 follows the Active
islanding methodology by allowing frequency of the Powerwall 3 to be inherently unstable
in the absence of a reference frequency (frequency instability).
Note
The model numbers in this
manual call out "-XX-Y" for the suffix of the equipment model number. The wild
cards are defined as follows:
- "X" is a number and the one number in the model number representing a style code; form, fit, and function are not changed, and these numbers have no bearing on compliance.
- "Y" is a letter, and the one letter in the model number representing a pedigree; form, fit, and function are not changed, and this letter has no bearing on compliance.
Solar Technical Specifications

9Powerwall 3 is designed to operate in all climates from temperatures of -20°C to 50°C. Performance may be de-rated at operating temperatures above 40°C.
Note
Early Powerwall 3 enclosures are non-powder
coated and can display natural signs of aging on the aluminum. This is expected
and has no impact on performance or durability.
