24V external power supply operation

What does EV mean?

This indication flickers when the inverter is being powered by the 24V external power supply, but the main circuit power is not supplied. It serves as an alarm, informing the technician that the main power source is absent or insufficient, although the inverter itself is not tripped. This can prevent unexpected startup when main power is restored.

Complete Troubleshooting Guide

1. 1

   Turn ON the main power supply for the inverter's main circuit.

2. 2

   If the indication persists with main power ON and external 24V supplied, check the main circuit power supply voltage.

3. 3

   Ensure the jumper between terminal P/+ and P1 is securely installed if it was previously removed.
