Install Multiple Powerwall 3 Units
Leader to Follower Communication | Ethernet (see Prepare Ethernet Wiring with RJ45 Connectors) |
Internet Connection for Multiple Units | Option 1: The Leader Powerwall 3 is connected to customer router over Wi-Fi |
Option 2:
Either the first or last Powerwall 3 (can be Leader
or Follower) in the chain is connected to customer router via
Ethernet Note Only connect the router to a Powerwall 3 at either
end of the chain; do not connect it in the middle of the chain
(see Connecting Powerwall 3 Units via Ethernet for example diagrams). |

Maximum Wire Length Between Units | See Plan Cable Length Between Components |
Overcurrent Protection Devices | Each Powerwall 3 requires its own circuit breaker |
Splitting PV Production Between Multiple Powerwall 3 Units | Splitting PV production (strings) equally between the Powerwall 3 units is preferred but not required |
Connecting Powerwall 3 Units via Ethernet
All Powerwall 3 units must be connected via Ethernet. The units can be connected in any order, so long as each unit is connected to at least one other unit.
