Definitions, Safety, and Limitations4 Power Xpert Solar 1500/1670 kW Inverter MN141001EN—October 2014 www.eaton.comPhotovoltaic Ground-FaultThe inverter is designed for grounded PV systems only. Itis furnished with photovoltaic Ground-Fault Detection andInterruption (GFDI). If the inverter detects a PV Ground Fault,it will interrupt the fault-current within the inverter, set aground-fault alarm error message visual on the HMI (LCD)and Modbus, stop exporting power (turn-off) and open CB1,DS1, DS2, and DS3. Additional corrective and protectiveactions will be required when this alarm is active. Refer to“Troubleshooting Ground Faults” on Page 43 for a detaileddescription of the ground fault detection and interruptioncircuit: operation and servicing requirements.By Code, the PV system must be labeled as illustrated,below. Look for such labeling.Figure 2.
