Xantrex Freedom EX 4000 error code E01
Low battery cutout (LBCO) shutdown: the 48 V bank stayed below the LBCO setting for longer than the LBCO shutdown delay timer. The Freedom EX Remote Panel 808-0817-03 shows E01 and the buzzer sounds a single one-second low-battery beep first; after the delay the inverter output shuts down. Recovers when voltage rises above LBCO + LBCO Hysteresis (default 6.0 volts).
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.
