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.
