Questions people ask
What does this product actually do?
It provides a physical switch that disconnects the DC power connection in a compatible vehicle-to-home or backup energy system.
Can any EV or plug-in hybrid power a home?
Any vehicle with V2L (vehicle to load) can be used to power a home, and that includes both EVs and plug-in hybrids, because V2L lets the vehicle act as a power source for your appliances or circuits. This switch is the dedicated point that safely isolates that connection during servicing or an emergency. Fuller systems that feed the home automatically (V2H) or export to the grid (V2G) also need a vehicle, charger and electrical design that support them.
Can I install it myself?
No. It should be installed and commissioned by a licensed electrician using the approved wiring diagram and confirmed product ratings.
Does it work with solar?
It can form part of a broader installation that includes solar, batteries and an EV. Compatibility depends on the complete system design.
