Verification And Commissioning Test - Xantrex GT2.5-NA Owner's Manual

Verification and Commissioning Test

Purpose
This procedure is designed to verify correct operation of the Xantrex Grid Tie Solar Inverter both on initial
operation and periodically through its life as required by the utilities.
Commissioning Test
Follow the startup and monitoring procedures as documented in Chapters 4 and 5.
When operation of the inverter has been verified and the unit is producing power, run the disconnect test as
described in this section.
Verification Test
Periodically run the disconnect test. The inverter must respond within the 2-second limit for compliance
and then hold off on producing power for the required delay (default value of 5 minutes).
Disconnect Test
This test requires that the AC circuit for the inverter be switched off. This can be accomplished by
switching the breaker on the main panel that feeds the inverter(s). As an alternate, the disconnect for the
home or business may be used as well. Have someone watch the front panel of the inverter. Within 2
seconds of switching the breaker, the green light on the front of the inverter must go out. The display will
respond with an AC Fault display, indicating that the AC is out of the operating range.
Re-energize the breaker to the inverter. The unit will respond by beginning its countdown. The green light
will be off during this time. Five minutes after applying AC (default value), the green light will turn on and
the inverter will begin to push power to the grid. The display will then return to its on-line display showing
the power being produced along with the total kWh produced to date.
Note: The default voltage, frequency and reconnect delay values as defined by UL1741 and CSA 107.1-01
are programmed into the unit at time of shipment from the factory. No changes to these settings can be
made in the field by the user. Only authorized personnel with the utility's permission may change these
settings. Contact Xantrex Technology to gain permission and the procedure/equipment to make these
changes.
