Solar Panel Commissioning Procedure

Date

Client Name

Location

Solar Panel Personel

Connect power sources to systems (this includes connecting PV module wire runs)

AC and DC disconnects need to remain in “OFF” position

Fuses are not connected

Test DC voltage and polarity

Make sure to use proper meter settings for DC

Test after connecting PV modules in series and measure

Expected voltage (from calculation of modules)

Voltage polarity

Test AC voltage at inverter output

Make sure to use proper meter settings for AC

Test Line to Line and Line to Neutral

Compare with inverter AC voltage (specs sheet)

If inverter has settings for more than one connection, match your service setting for voltage 

After this step, return fuses if applicable

Start-up procedure

Lift AC disconnect lever (inverter to grid)

Lift DC disconnect lever (PV to inverter)
