Powerwall 3 AC and PV Wiring


	Terminal Name	Recommended Wire Color	Wire Gauge
1	N (Neutral)	White	10 - 4 AWG (6 - 25 mm²)
2	L2 (Line 2)	Red	10 - 4 AWG (6 - 25 mm²)
3	L1 (Line 1)	Black	10 - 4 AWG (6 - 25 mm²)
4	Ground terminals	Green	12 - 4 AWG (2.5 - 25 mm²)
5	MPPT Positive PV inputs (PV 1+, 2+, 3+, 4+, 5+, 6+)	Red	10 - 6 AWG (6 - 16 mm²)
6	MPPT Negative PV inputs (PV 1-, 2-, 3-, 4-, 5-, 6-)	Black	10 - 6 AWG (6 - 16 mm²)
7	MPPT Parallel Jumper Slots	Use provided jumpers (Tesla P/N: 1784893-xx-y)*

*Do not make jumpers. Use only the jumpers included in the Powerwall 3 accessory bag.

Note

The leftmost terminal in the AC connector is not used.

Note

AC power output terminals are rated to a minimum of 90°C.

Note

Use only copper conductors in the PV connector and GND terminals.

Note

PV input terminals (MPPT DC inputs) are rated to a minimum of 75°C.

Note

Powerwall 3 units with P/N 1707000-11-L or 1707000-21-L have a unique PV connector in which the positive (5) and negative (6) conductors for each string are connected side-by-side. As depicted below, all other Powerwall 3 units have a PV connector in which the positive (5) conductors are connected on the left, and the negative conductors (6) are connected on the right.
