0013 | AC Voltage High | S | This fault indicates that the utility | • Utility grid voltage rose | |
|
|
| grid voltage is above or rose above |
| above the allowable |
|
|
| the maximum allowed value of 110% |
| limit |
|
|
| of nominal Vac for greater than |
|
|
|
|
| 2 seconds, or 137% of nominal Vac |
|
|
|
|
| for greater than 2 cycles. This fault is |
|
|
|
|
|
|
| |
|
|
| voltage has recovered within the |
|
|
|
|
| acceptable operating range, the |
|
|
|
|
| PV100S will qualify the value and |
|
|
|
|
| automatically clear this fault and |
|
|
|
|
| resume normal operation after |
|
|
|
|
| 5 minute delay period. |

|
|
|
|
|
| |
0014 | Grid Interface Failed | S | This fault indicates that the PV100S | • K1 was opened while | |
|
|
| has detected an imbalance of AC |
| the PV100S was |
|
|
| output power of 5 kW or greater |
| processing power |
|
|
| when compared to the DC input | • | K1 is inoperable |
|
|
| power for more than 6 seconds. This | • | K3 is inoperable |
|
|
| normally means that the connection | • | SSR1 is inoperable |
|
|
| of the PV100S to the grid has failed. | • | TS1 is open |
|
|
|
|
| |
0015 | Grid Disconnection | S | This fault indicates that the PV100S | • S1 was opened while | |
|
|
| has detected a sudden AC voltage |
| the PV100S was |
|
|
| increase of greater than 40% of the |
| processing power |
|
|
| nominal |
|
|
|
|
| normally is the result of a sudden |
|
|
|
|
| disconnection from the Utility grid |
|
|
|
|
| while the PV100S was processing |
|
|
|
|
| power. |
|
|
|
|
|
|
|
|
0016 | DC Contactor | S | This fault indicates that upon entering | • | K2 is inoperable |
| Circuit |
| the Power Tracking State, the | • | SSR2 is inoperable |
|
|
| PV100S has detected that the PV | • | TS1 is open |
|
|
| voltage has remained above the PV |
|
|
|
|
| Start Voltage threshold even after |
|
|
|
|
| commanding the DC contactor to |
|
|
|
|
| close. This condition is indicative of a |
|
|
|
|
| DC contactor circuit failure. |
|
|
|
|
|
|
|
|
0020 | PV | S | This fault indicates that the PV100S | • | CT4 is inoperable |
|
|
| has detected a DC current greater | • CCU2 ±15 Vdc Power | |
|
|
| than the maximum allowed value of |
| Supply is defective |
|
|
| 712 Adc. | • P3 on CCU2 is loose or | |
|
|
|
|
| disconnected |
|
|
|
| • PV system wiring short | |
