6 FAQs about [Photovoltaic inverter unpacking test method]

Can a stand-alone photovoltaic system be tested?

Abstract: Tests to determine the performance of stand-alone photovoltaic (PV) systems and for verifying PV system design are presented in this recommended practice. These tests apply only to complete systems with a defined load. The methodology includes testing the system outdoors in prevailing conditions and indoors under simulated conditions.

Can a PV system be tested if a load changes?

These tests do not cover PV systems connected to an electric utility. Test results are only relevant to the system tested. If the PV system or load changes in any way, then the tests should be rerun on the modified system. It may be desired to run performance tests on the load (s).

Can a PV inverter be connected to a low voltage distribution system?

This document is most applicable to large systems where PV inverters are connected to utility high voltage (HV) distribution systems. However, the applicable procedures may also be used for low voltage (LV) installations in locations where evolving UVRT requirements include such installations, e.g. single-phase or 3-phase systems.

How do you test a 500 KW PV system?

Turn the system on and verify that there is no current on the equipment grounding conductor. (Note: it is normal for less than 10 mA to flow without ground faults in a 500-kW PV array.) a PV system. “Megger” testing, as insulation testing is often called, is a name brand of a product from a company that pioneered this particular type of testing.

Can a PV system be tested on a modified system?

Test results are only relevant to the system tested. If the PV system or load changes in any way, then the tests should be rerun on the modified system. It may be desired to run performance tests on the load (s). Such tests may be found in other documents, for example, Servant and Aigullon [B7] describe how to test a lamp in a photovoltaic system.

How do I start a 500 KW PV inverter?

(Note: It is normal for less than 10 mA to flow without ground faults in a 500-kW PV array.) Begin the startup procedures for the inverter according to the manufacturer’s installation manual. This generally includes closing the ac breakers and disconnects before closing the dc disconnecting means.
