Xantrex Freedom EX 4000 error code E02
High DC input voltage shutdown: battery voltage above 64.0 volts (setting range 58.0 to 70.0 volts). The remote panel shows E02 alternating with the battery voltage and the Alert LED turns on. The guide also lists this as 'High input voltage (error code E02)' in Troubleshooting Reference. CONFLICT: the LCD event-code Table 6 uses code 2 for 'AC Output Over 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.
