Can multiple EV-Chargers G2 be used in parallel, and what are the requirements?

Yes, the EV-Charger supports a parallel function:

• Solar Scene: Up to 2 EV-Chargers can be paralleled (1 primary, 1 secondary). The primary device collects grid/PV data and allocates power (default ratio 1:1, adjustable to 1:2 or 2:1).
• Standard Scene: Up to 20 EV-Chargers can be paralleled (1 primary, multiple secondary). Charging power is evenly allocated among devices.

Requirements

• All paralleled EV-Chargers must be the same model and have the same firmware version.
• Connect the primary device's COM2-M- port to the secondary device's COM1-S- port (use RJ45 couplers if needed).
• Enable the parallel function on the primary device's App: "Advanced setting" > "Parallel Setting" > Select "Primary"; the secondary device will automatically switch to "Secondary".
