Warranty-voiders and V2H setups, ye be warned


If using the Setec in North America, the biggest limitation is that the inverter is single phase, not split-phase. If planning to use with North American household appliances, running the 220V system must be used with a transformer of somekind. There are some potential fixes, such as adding an external transformer to drop voltage down to 120Vac. A project I never pursued was a transformer to split phase. As this requires additional modification to the Setec unit, I have opted to not pursue this configuration but curious to learn from others how they’ve done it.


Here is what NOT to do: modify the Setec device to connect to your home, but not have the grid power fully disconnected. This will cause a back surge of power that can create a thermal event in the Setec unit and destroy all components in the car. How do I know? Perhaps a good guess...


If you are planning to connect to your home, triple check and test the transfer switch is fully disconnecting the home from the grid.


For the V2H hobbyists out there that are working on this configuration, I recommend researching the grounding configuration. The Setec unit is designed as a floating ground and depending on any modified configuration may need a different grounding solution.

CHAdeMO

As much as I love the CHAdeMO standard, the Setec unit will be a risk as it is limited to CHAdeMO vehicles.

Future Products

There are products coming to market with a lot more functionality.

- AC-V2L/V2H: these products have a transfer switch and leverage the power electronics inside the vehicle. Ford F-150

- DC V2H/V2G: A grid-interactive system, where the equipment can charge and discharge while the home is still connected to the grid

- DC V2L/V2H: The system can operate with an emergency back-up power configuration.


Will put together blog posts on this topic soon.
