Conventional portable power stations typically adopt a ""floating ground"" design, meaning they lack a true physical earth ground connection. As a result, Electric Vehicle Supply Equipment (EVSE)—such as Level 2 portable chargers—are equipped with built-in safety mechanisms including ground continuity monitoring and residual current protection (RCD). When connected to a floating-ground power source, the EVSE detects the absence of a low-impedance path between the neutral and ground lines, interprets this as a ground fault, and actively disengages its internal relay to cut off the charging circuit. This is not a malfunction of the power station, but rather a mandatory safety protection enforced by the EVSE.
To address this, the Jackery Grounding Adapter provides a ""simulated grounding"" function (not a physical connection to the earth), which allows the EVSE to pass its safety checks and thereby enable EV charging. This adapter is compatible with three models: Homepower 3600 Pro Max and Explorer5000 Plus. Please note: user of Explorer5000 Plus must complete a firmware update prior to use—devices that have not been updated will not support this accessory. Homepower 3600 Pro Max does not require a firmware update.
Once the adapter is installed, please follow the product manual carefully to complete the setup. Connect the vehicle charging cable to an available 120V or 240V AC output port on the power station, then follow the operating instructions on your vehicle's onboard charger or charging station to initiate the charging process.
Important Safety Warnings:
AC Mains Charging Prohibited: When the Grounding Adapter is connected, charging the power station via AC mains power is strictly prohibited to avoid equipment damage or safety hazards.
Parallel Port Disabled: When used with Explorer 5000 Plus, or Homepower 3600 Pro Max, the device's parallel port will be automatically disabled once the grounding adapter is connected. Please do not attempt to connect or expand via the parallel port.
Please be fully aware of the above technical limitations and strictly adhere to electrical safety practices during operation. Should you have any further questions, please do not hesitate to contact us.
