Go Power error code Battery Over-Voltage (>17.5 V)
Battery-input voltage above 17.5 V (LCD 'Battery over voltage than > 17.5V', flashing LED) - typically another charge source (RV converter / DC-DC / alternator) over-charging. Check the converter/charger set-point (should never exceed 14.7 V).
What to check, and in what order, is in the app. The flow Go Power Solar Controller — Entry Diagnostic 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.
