    • Testing is an important part of the OpenEVSE build process. This guide provides testing recommendation both for the user and those developing hardware and software.

    • OpenEVSE performs extensive self test during boot, before closing relays/contactors and while operating.

    • Basic Testing is recommended for all builders after building your charging station and whenever maintenance is performed.

    • Advanced testing shall be performed by hardware and software developers before releasing "Stable" firmware or a new hardware revision.

    • For builders wishing to better understand how a charging stations work, Advanced Testing may be performed.

    • Many advanced tests require live AC Power. Use extreme caution when working near energized high voltage components.

    • During the boot process OpenEVSE will run a Power on Self Test (POST).

    • If the POST fails by indicating any Error condition or a RED LED/LCD please refer to the Troubleshooting guide before proceeding.

    • EVSE states can be tested with a few resistors and a diode, and EV Simulator or an EVSE Tester.

    • Power on OpenEVSE Charging Station with the GFCI coil with self test loop disconnected.

    • The OpenEVSE Charging Station should fail the boot process with "Error GFCI Self Test Failed" and indicate red on the LED/LCD.

    • If the Power on Self Test deos not fail with the coils disconnected, check that GFCI Self Test is enabled in the Service Menu.

    • If GFCI self check is enabled and the test does not fail please refer to the Troubleshooting guide.
