Go Power error code Solar Panel Over-Voltage (>26.5 V)
Solar panel open-circuit voltage above 26.5 V at the controller input (LCD 'Solar panel over voltage (> 26.5V)', flashing LED). PWM units require panels wired in PARALLEL; the GP-PWM-30-SQ array Voc must not exceed 25 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.
