Inverter Operation
Commissioning Procedure
The Power Xpert Solar 1500/1670 kW Inverter requires a
commission process to be completed to establish the date of
commission and start-up for warranty purposes.
Commissioning requires a detailed sequence of checks and
manual operation of the inverter at increasing power levels,
the details of which are not in this manual. Commissioning
the inverter will also mean the site is in compliance with the
PV-array system and utility interface, both of which are
outside the scope of this inverter manual. Complete all the
PV-site commissioning steps prior to revenue service.
For commissioning to be complete, the inverter must
synchronize to the utility grid, exporting power without
faults, and return to the sleep mode and wake-up upon rising
irradiance. Whenever possible, allow the inverter to return to
sleep-mode and wake-up the next morning by the natural
process of sunset and sunrise, while Eaton commissioning
personnel are on-site. Eaton recommends the inverter power
production to be monitored for 72 hours (3 sunny days) after
commissioning to ensure proper operation. Please refer to
Power Xpert Solar 1500/1670 kW Inverter Station Block
Commissioning Tasks for more details.
The power exported to the grid during commissioning (peak
kW and accumulated kWh) will be dependent upon the
available photovoltaic power (kW) during the time of
commissioning and may not, nor needs-to-be, the inverter's
full rated power or that of the photovoltaic system. Follow
and complete the inverter commissioning guide appropriate
to the inverter:

Energize and Operation Procedure: Automatic
Operation
Do not proceed to the energize and operate the inverter
unless authorized.
Inverter Start-Up Procedure—Automatic Operation
1. Close CB2 to energize control circuits.
2. Close PV source-combiner or external PV-disconnects to
apply array voltage to the Inverter DC collector bus.
3. On the HMI select the Operation tab and navigate with
the arrows to the Configuration page. Refer to image
below.
4. On the Configuration page; select AUTO
The Local, P Priority, and Fixed Q settings will already
be selected.
5. On the Operation tab, navigate with the arrows to the
Local Setpoints page to verify the power setting of the
inverter. This value should have been set during the
commissioning of the inverter.
