What is an inverter certification test?

The inverter certification tests must also provide data to show maximum power tracking effectiveness, efficiency variations associated with power line voltage, environmental effects, and losses that occur at night and during protective shutdowns.

Which inverter is exempt from a utility voltage test?

Listed inverters with integral controllers are exempt from this test. Purpose: Verify the proper operation of the inverter under loss of utility condition. In this test, the time it takes for the inverter to disconnect from the ac grid after loss of utility voltage is determined.

What is an inverter control test?

The test will consist of demonstrating proper functional operation of the control and protective features. The majority of these tests are related to the inverter since most of the system operation and control is via the inverter. In some cases, devices external to the inverter will handle one or more of these features.
