Xantrex Freedom EX 4000 error code E03
Unit overload or AC output short circuit (Troubleshooting Reference). The guide's overload text: a warning does not stop inverting, but after a sustained overload the inverter shuts down. CONFLICT: Table 6 has no code 3; its AC overload codes are 63/64/65.
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.
