Q: What does code P2CC5 mean?

Generator Inverter Power Supply B Circuit/Open. P2CC5 indicates that the generator inverter has detected an open circuit or power supply fault on its 'B' circuit, which is a secondary power feed used by the inverter control electronics. The inverter's internal diagnostics monitor this supply and set the code when the expected voltage is missing or out of range, preventing the high-voltage generator from producing charge.
