Presented are high-voltage (HV) electrical systems pairing solid-state relays (SSRs) with electromechanical contactors for optimized galvanic disconnect, methods for making/using such systems, and vehicles equipped with such systems. An HV electrical system includes a first circuit loop that connects a rechargeable energy storage system (RESS) to an electrified powertrain. A second circuit loop, which is parallel to the first circuit loop, connects the RESS to a charge inlet of a battery charging system. A first contactor switch on the first circuit loop serially connects with the powertrain's electric motor and a first terminal of a RESS battery assembly. A second contactor switch on the second circuit loop serially connects with the charge inlet and the first terminal. One or more SSR switches electrically connect in series with a second terminal of the battery assembly, the electric motor and/or charge inlet, and the two contactor switches across the battery assembly.
