I have a solar panel array on my roof and generate enough power for the house but not quite enough for the house and the i3. I would like to expand the roof array just a little to cover the car completely but if I do so my utility will consider it a new installation and I will lose my grandfathered net billing status. What I can do is to go completely off grid with the j3.
An off grid setup typically has a battery bank fed by a charger and feeding an inverter. This is expensive, leading me to ask this question:
Would it be realistic to design an EVSE fed directly from solar panels? Remember that the output from the panels varies from zero to several Kilowatts during the day and is DC. If such an EVSE cost less than a battery bank and inverter charger then it would be a commercially viable product.
