How to Run CEI Auto-test Function on LUXPOWER Inverter

Based on CEI 0-21 requirements, all inverters that feed into the utility grid must be equipped with an auto-test function. During the auto-test, the inverter sequentially checks the over-voltage, under-voltage, over-frequency, and under-frequency protection time. After completion of the auto-test, the inverter automatically switches back to feed-in operation. Installer needs to submit the auto-test result to power company when finish installations.

In order to save installation time and make the auto-test function easy to use, two methods have been released to execute the auto-test function.

Method 1: Run the auto-test procedure via LCD.
