AC Overload Protector
This is a mechanical safety breaker located on the side of the unit that triggers during high-amperage surges. If the internal contactor has failed or remains mechanically 'open' after a surge, the AC circuit cannot be completed, preventing any power from reaching the internal charging transformer.

Bi-directional Inverter Board
The Delta Pro utilizes a complex bi-directional inverter to convert AC wall power into DC for the battery. A failure in the high-side MOSFETs or the synchronization logic on this board prevents the unit from rectifying input voltage, resulting in a 'connected but not charging' state.

BMS Control Module
The Battery Management System acts as a digital gatekeeper. If the BMS detects a cell voltage deviation beyond the safety threshold (often evidenced by error codes like 077), it will command the charging relays to stay open to prevent potential thermal runaway, effectively disabling all charging inputs.
