Mid Circuit Interrupter Specifications (P/N MCI-2) PV Rapid Shutdown Equipment (PVRSE)
Electrical Specifications
Note
MCI-2 and MCI-2 High Current are referred to collectively as MCI-2, as the only differences between the
two variants are the IMP and ISC ratings.
| MCI-2 | MCI-2 High Current | |
|---|---|---|
| Nominal Input DC Current (IMP) | 13 A | 15 A |
| Maximum Input Short Circuit Current (ISC) | 17 A | 19 A |
| Maximum System Voltage | 1000 V DC1 | |
| Maximum Disconnect Voltage | 165 V DC2 | |
1Maximum System Voltage is limited by Powerwall 3 to 600 V DC.
2Maximum Disconnect Voltage is the maximum voltage allowed across each MCI in the open position (Rapid Shutdown Initiated). An individual MCI-2 has a voltage rating of 165 V but in combination (connected in the same string) their voltage ratings are additive.
