FAQ
Can this switch be used with non‑inverter generators?
While the switch is optimized for inverter generators rated up to 3500 watts, it can operate with any generator that matches the 16 A, 250 V specifications, provided the wiring conforms to the 2‑way circuit design.
Is Wi‑Fi required for basic operation?
No. The switch functions fully as a manual push‑button device. Wi‑Fi is an optional feature for remote status monitoring and integration with smart home platforms.
What does the IP00 rating mean for outdoor use?
IP00 indicates the unit has no special protection against water ingress. It is intended for dry, sheltered locations such as generator enclosures or covered work areas.
How is the switch installed?
Installation involves plugging the connector into the generator’s control port and securing the weld terminals to the appropriate circuit wires. Detailed wiring diagrams are included in the product manual.
Does the switch support multiple colors or models?
The current model is available only in red with the model number 100397. Future color variations may be released based on demand.
