Test Run

Checking the PV Array DC Voltage

To check the PV array DC voltage:

(1) Uncover the PV arrays and expose them to full sunlight. The sunlight must be intense

enough to produce the required output voltage.

(2) Measure the PV array open circuit DC voltage across the DC positive (+) and negative (-)

terminals. This voltage must greater than 70 VDC (to energize the electronics) and less

than 320 V

DC (should be less than 350 VDC to prevent damage to the inverter).

Checking the AC Utility Voltage

To check the AC utility voltage:

(1) Switch on the main and inverter breakers in the main electrical service panel.

(2) Using an AC voltmeter, measure the AC open circuit utility voltage between L (Line) and

N (Neutral). Ensure the voltage is at approximately the nominal value. The inverter

operates with a line-to-neutral voltage range around the nominal value.

See "Output" section in "Electrical Specification" (page 23) for the utility voltage operating range for your inverter model.

After performing the voltage checks, reattaching all covers that were removed during installation and startup.

Starting Up the Inverter

To start up the inverter:

(1) Switch the AC disconnection switch (breaker) to the ON position.

(2) Switch the DC disconnection switch (breaker) to the ON position.

• The inverter starts up automatically.

• It takes approximately 1 minute to startup ON-Grid LED (Green) flashes.

(3) Check the inverter display. After startup is completed, ON-Grid LED (Green) lights up

and output power is displayed on the display panel.

(4) Replace the front panel, pressing up the panel to fit it to the packing (push front panel

up to seal and insert screw).

Tightening torque 6 in-lb (0.7 Nm)

WARNING: SHOCK HAZARD

Before reattaching covers, turn OFF the breaker switches in the main utility service panel and

disconnect device for PV array.
