WFCO WF-5318 / WF-5320 error code FAULT
Control-panel fault indicator: the display shows an overload 'or other type of fault condition' - the manual does not print a per-condition table. The protection stops that exist besides overload are: over temperature (restarts once when cool, then remains off), ac output short circuit (line and neutral connected together - restart after correcting), high battery voltage (alarm above 15 volts, stop above 16 volts) and low battery (its own BATT. LOW indicator).
What to check, and in what order, is in the app. The flow WFCO WF-5318 / WF-5320 inverter - no 115 V output (shore, battery or dark remote panel) walks this code step by step with the pass/fail measurements, wiring schematics and procedures that go with it, and it works offline in the bay.
