Some models include built-in WiFi instead of requiring a dongle:
| Inverter Type | Serial Prefix |
|---|---|
| Gen 2 Hybrid | WG |
| Gen 3 Hybrid | WH |
| All-in-One | WJ |
| Giv-Gateway | WK |
To enable internal WiFi, remove the inverter’s bottom cover and set the DIP switches to WiFi Mode (see the installation manual). Even when using LAN, secure the WiFi module to prevent network exposure.
