Common use of Photovoltaic Clause in Contracts

Photovoltaic. Combiner Box Tests - For repetitive source circuit wiring, the following procedure must be followed for each source circuit in a systematic approach, i.e., east to west or north to south. All data are to be recorded on a combiner box check list. The following testing will take place around noon on a cloudless day: □ Inspect the combiner boxes to ensure that all wiring is correctly and securely installed. □ Where wiring is visible, check to ensure it is UL listed and includes labelling to show voltage rating, and that voltage rating is appropriate. □ Check open-circuit voltage (Voc) of each of the source circuits to verify that it provides the manufacturer‘s specified voltage in full sun. Verify the polarity of each source circuit in the DC string combiner box by paying particular attention that there is NEVER a negative measurement. □ Check Max Power Point current (IMPP) of each of the source circuits to verify that each provides the manufacturer‘s specified current in full sun. □ Confirm that no ground faults are present in the DC wiring. □ Test the Insulation Resistance of the DC conductors from the combiner boxes to the Inverters each conductor to ground.
