Inverter Main Board Assembly
An overload error persisting with no load indicates a short-circuit failure within the DC-to-AC conversion stage. The internal current-sensing resistors or H-bridge MOSFETs have likely failed in a closed state, causing the system to detect excessive current flow during the diagnostic startup sequence. Replacing the complete Inverter PCBA is the only reliable resolution as these components are surface-mounted and calibrated to specific firmware thresholds.

Battery Management System (BMS) Control Board
If the inverter board is functional, the BMS may be reporting incorrect current telemetry due to a failure in the shunt sensing circuit. A drifted resistor or a failing analog-to-digital converter (ADC) on the BMS board can provide false voltage drops to the microprocessor, triggering a software-level overload lockout despite safe physical operating conditions.

AC Output Socket Module
Physical carbon tracking or a partial short within the output receptacle housing can create enough leakage current to be detected by the high-sensitivity ground-fault or over-current protection logic. This is more common in high-humidity environments where conductive bridges form across the internal AC bus bars.
