The max charge rate the i3 can handle is 7.4Kw. 30A*240vac = 7200W. Your supply voltage may vary slightly from that nominal value of 240vac, and either above or below will affect the charge rate as well. As an example, a unit capable of 32A at 240vac, would only provide 7.04Kw at 220vac.

The latest i3 software changes the charging logic based on the temperature, and if (when) you have that installed, could limit the charge rate by as much as 30%. This is related to an issue with the onboard charge unit (KLE) and they should have a resolution for this (they say) either late this year or early next. The s/w mod should keep the KLE from failing to charge at all in the interim.
Thanks for your, as always, well informed advice!
