InverterFault

Also applies to:E-CHO-SI5KS2E-CHO-SI8KS2

What it means

Volt Cons Fault — Voltage consistency fault between master and slave samples.

Cause: The master and slave voltage-sampling channels disagree beyond tolerance, so the inverter cannot trust its voltage measurement. This is an internal sampling-circuit fault.

How to fix it

  1. Power down the inverter, wait 5 minutes for capacitors to discharge, then restart.
  2. If the fault recurs immediately or repeatedly, record the exact code and contact your installer or the manufacturer's service line.
