Not TOU-2: Break even production + 350 kWh super off-peak = Pay for 350 kWh super off-peak
With TOu-2: Break even production + 350 kWh for charging = Get credit for 100+ kWh super-off peak.
That's a 450 kWh swing. Won't work nearly this well in winter but other than Dec-Jan the winter months is when I end up with the most surplus production.
Interesting. That's when I end up with no surplus production, and quite a bit of consumption.
Time will tell but an estimate would be somewhere between $50 and $250 for 4200 kWh.
With EW you can figure out how this would work for you, even without the decimal. FWIW the meter seems to be precise.
Which, as I've said, is what I'm doing.
So far--with only about a month's worth of data with the EV meter in place (and one week of that not too meaningful, as we were out of the country, so no EV charging)--EV-TOU-2 would have saved us a little under $60. Damn, that's good! Would've been less had we been charging for that extra week. And, we'll see how it goes once those low-PV-production months come around.
Yes, the meter data is more precise--Matt from the ET Project sent me a spreadsheet with 15 minute data from my meter, which shows values down to the wH. That also showed why, in a full month that I never used the Blink to charge a Leaf (and I even had it unplugged a significant amount of time), I still pulled 9kWh per that meter. Energy Wave showed 0kWh for that whole period--insufficient precision. But those 5 wH intervals add up!
