Startup Checklist

Mechanical Installation
 Make sure the inverter is securely installed and all mounting fasteners are tightened to the specified
torque values. See Section 3.2 Inverter Size, Spacing and Mounting
Electrical Connections
 Turn the DC Switch on the inverter to the "OFF" position.
 Turn the AC Switch on the inverter to the "OFF" position.
 Verify all conductors are landed on the correct terminals.
 Verify all connections are tightened to the specified torque values. See Section 3.5, 3.8 and 3.9.
Electrical Check

Startup Steps

Follow these instructions when energizing the unit:
 Verify inverter wiring compartment cover is installed and secured using all fasteners.
 After completing the electrical connections and electrical checks, energize the site AC Breaker to
connect grid AC voltage to the inverter.
 Connect the PV source circuits to the combiner and energize the PV output circuit from the combiner to
the SOLECTRIA XGI 1500 wiring box DC terminations.
 Turn the AC switch on the inverter to the "ON" position.
 Turn the DC switch on the inverter to the "ON" position.
