Charging problems with Renault Zoe at 22kW Wallbox

Hello! In November I bought a Wallbox Copper SB 22kW. There were only problems with it and after the proposed installation options the box finally burned. Then I got a new one. But also the new one could only charge with 11kW and the charging process always stopped with a mistake when the current 16A (11kW) exceeded. Now I am without charging station. There are not many cars (only Renault?) that can charge with 22kW. Someone has a Zoe and a charging station that with 22kW invites and works well? Greetings, Jukka
