Engineer was full of cold/flu and had to cancel the previous day's appointment; understandable in the circumstances. Unfortunately, on installation, the PCB was found to be damaged and had to be replaced with one from another Unit. The serial number of the board was not updated on the system and therefore only charged at approx 1.2kw. Support were good in getting it resolved, but it took two days and several calls before the engineer confirmed the new board number and enabled the settings to be adjusted to where they should have been. I've rated this as acceptable as the process from order to install was quick and we currently have a PHEV, but had this been after the full EV arrived, it would have taken 2 1/2 days or so to charge; that would not have been acceptable!
