Fault codes

What is it telling you?

There is no universal fault code standard. The same number means different things on different brands — code 25 alone means three different things across these inverters. Pick your device, or search every code at once.

Codes and their meanings are drawn from each manufacturer's own published fault tables. All explanatory text here is original. There is no universal fault code standard: the same number means different things on different brands, and sometimes on different models from the same brand. Always confirm against the manual revision loaded on the unit in front of you.
