Questions to the Go-eCharger Binding

Hey there, I’m thinking of buying a go-e charger for my future electric car. However, the binding information tells me it is for 7.4kW or 22kW. The go-e chargers are sold in 11kW and 22kW versions. Does this binding support the 11kW version as well? Has there every been a 7.4kW version as this one is not in the shop or is it just a typo in the binding description?
