What it means
Reserved — Reserved code.
Cause: This code position is reserved in the E-CHO SI fault table and is not tied to a documented fault condition. If it appears, treat it as an undefined internal protection event.
How to fix it
- Power down the inverter, wait 5 minutes for capacitors to discharge, then restart.
- If the fault recurs immediately or repeatedly, record the exact code and contact your installer or the manufacturer's service line.
