Can you share how you signed up to become a test site? I also have an enphase system and would see significant benefits from being able to limit peak grid usage with everything in our house except the water heater being electric.
When the press release came out, I phoned the contact on the release.
Thanks, and love that thinking outside the box!
Almost all (all that I'm aware of) EVs throttle significantly above 80%. My Lightning throttles back to around 60kw at 80%. It's not an 800V architecture problem.
I owned an Ioniq 5 and charged it many times at EA using a 350kW charger. It would drop to 4-5kW at 80% for 2-3 mins before ramping back up. If charging on a 150kW charger that doesn’t happen. Not every EV is as affected at 80%, it depends upon the charging curve and rate. If it’s too aggressive in the beginning, the end suffers. The Tesla Model 3 LFP has a nice flat curve up to 90% before tapering to 60kW. My lightning SR will not DCFC over 90% without a failed charge/error. That might’ve changed with the new update!
