In the event of a fault condition, the PV225S will immediately stop processing power and execute an immediate orderly shutdown, open both the main AC and DC contactors, and remain in a faulted state until the fault is remedied and cleared (manually or automatically).

  • Page 91: Clearing Faults Manually

    Clearing Faults Manually Faults associated with a grid disturbance clear automatically. These faults include: • 0010 (AC Frequency Low), • 0011 (AC Frequency High), • 0012 AC Voltage Low), and • 0013 (AC Voltage High) only. Once the AC voltage and frequency return to within the acceptable range, the PV225S will clear the fault and automatically restart after a 5-minute delay.

    Preventative Maintenance Chapter 5, “Preventative Maintenance” contains information and procedures for performing preventative maintenance on the PV225S 225 kW Grid-Tied Photovoltaic Inverter.

  • Page 104: Maintenance Safety

    Preventative Maintenance Maintenance Safety Prior to following any Maintenance Procedures, follow the System Shutdown and Lock-out and Tag procedure. Operational Safety Procedures Never work alone when servicing this equipment. A team of two is required until the equipment is properly de-energized, locked-out and tagged, and verified de- energized with a meter.

  • Page 105: Lockout And Tag

    Lockout and Tag Safety requirements mandate that this equipment not be serviced while energized. Power sources for the PV225S must be locked-out and tagged prior to servicing. Each energy source should have a padlock and tag installed on each energy source prior to servicing.
