Informational PurposesAn informational icon, calling your attention
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.

The Powerwall 3 part number and serial number can be found on the left side of the unit.

Solar Technical Specifications

Maximum Solar STC Input 20 kW
Withstand Voltage 600 V DC
PV DC Input Voltage Range 60 — 550 V DC
PV DC MPPT Voltage Range 60 — 480 V DC
MPPTs 6
Maximum Current per MPPT (IMP) 15 A5, 6
Maximum Short Circuit Current per MPPT (ISC) 19 A6

5Only applicable to Powerwall 3 units with 15 A IMP on the product label. Otherwise, Powerwall 3 has an IMP of 13 A.

6When PV strings are combined on the roof and the DC input current exceeds the MPPT rating, a jumper can be used to combine two MPPTs into a single input to intake DC current up to 30 A IMP / 38 A ISC (or 26 A IMP / 30 A ISC if Powerwall 3 is labeled with 13 A IMP / 15 A ISC).

Powerwall 3 with mid-circuit interrupters is an RS2 system for PV Rapid Shutdown.
