Xantrex Freedom EX 4000 error code 2 (AC Output Over Voltage)
[E] Escalating auto fault, any mode: AC output over voltage. Must occur 3 times in 2 minutes before it becomes a manual fault. NOTE: this is the LCD's code 2 - the guide's prose 'error code E02' names a different condition (high DC input voltage).
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.
