Now that I'm on solar with NEM2, I believe I'll be paying "non-bypassable charges" when charging at night using power generated during the day. These are small, but they add up - I'm calculating about $180 a year for 25,000 miles.
One way to avoid this is to charge during the day and constantly adjust the charging rate to match the solar generation. But that's a lot of work, so I've been looking for a "set and forget" solution.
There are some EV chargers (e.g. from Emporia, Wallbox, and probably others) that can supposedly charge a car using the excess power that would otherwise be sent to the grid. They do this by measuring the output through the electric main or communicating with a PG&E Smart Meter and adjusting the power delivered through the EV charger to keep the net exported power at around zero.
These seem like they would save money (by avoiding non-bypassable charges), and they'd also avoid using/straining the grid (which proponents of "NEM3" claim is a big deal that needs to be paid for).
Does anyone have experiences with these types of chargers or this type of charging strategy?
If grid usage is such a big deal (see discussion about NEM3), I also wonder why this this charging strategy isn't promoted more, and why there aren't incentives to install them.
