Startup and Verification Test
Electrical Shock Hazard
Installer may come into contact with components that have hazardous voltage and
energy.
Use proper safety equipment when energizing the inverter.
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 0.
Verify conduits from underground circuits are appropriately sealed
Electrical Check
Verify that the AC circuit breaker is appropriately sized. Refer to Section 0.
Test whether the AC voltage is within 5% of nominal
570V-630V for 600VAC models or 456V-504V for 480VAC models.
Verify that the AC phase conductors are oriented for clockwise phase rotation.
Test the polarity of the DC inputs. See Sections 3.8 and 0.
Verify that the DC open circuit voltage of the input PV circuit is less than 1500VDC.
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.
