Lithionics error code Overcurrent Protection
V9 status flag 'Overcurrent State': battery current exceeded the safety rating (the manual's table example is 400A; the actual value depends on the battery model and capacity). Continuous current above the preset limit for over 2 minutes opens the contactor.
What to check, and in what order, is in the app. A step-by-step flow walks this code with the pass/fail measurements, wiring schematics and procedures that go with it, and it works offline in the bay.
