The charger will be installed at half power (3.7kW) with load balancing via CT clamp – still 1.6 x faster than granny. Once the work has been completed by the DNO Bumblebee will come back and adjust the setting or you can easily do it yourself with or without guidence from me. I’ll find a flow chart later on how the DNO process works.
On the day of the install, I would not mention the letter and let the installer get on with what what the office has told them, as it’s upto the office to dealer with the DNO, not the paye installer, which could complicate matters, if you know what I mean.
