5. Commissioning
5.1 Pre-Commissioning Steps
Make sure that no high voltage conductors are energized.
Check all conduit and cable connection points to ensure they are tight.
Verify that all system components have adequate space for ventilation.
Follow each cable to ensure that they are all terminated in the proper places.
.
Ensure that all warning signs and labels are affixed on the system equipment.
5.2 Commissioning Procedure
Step 1
: With the DC switch off, energize the PV strings and then measure DC voltage of
the PV strings to verify that the voltage and polarity are correct. Turn on the battery and
check the battery voltage and polarity as well. If RSD is being used, the PV strings will be
at safety voltage (~0.6-0.6Vdc per module in the string).

Step 2
: Turn on the OCPD for the system and then measure the AC voltages line to
line and line to neutral. The backup side of the system will be off until commissioning is
complete. Turn the OCPD back off for now.
Step 3
: Turn the DC switch on and then the OCPD (AC breaker) for the system. If you are
using rapid shutdown, the voltage should increase after a few seconds. If it does not,
give the rapid shutdown initiation switch a clockwise turn so that it pops out.
Prepare a multimeter that can do both AC and DC amps
Verify that the inverter is secured to the wall and is not loose or wobbly.
