Ratio Solar 7.4 kW installation

When installing an EV charger, you actually have 2 choices;
1) You can install the Ratio Solar ev charger yourself
2) Let a charging station installer install it
In general, we always recommend having the charging station installed by a recognised charging station installer. After all, you don't want to compromise on safety and knowledge. People often underestimate how much is involved and mistakes can have major consequences. A recognised installer has completed the necessary installation courses, often including those provided by the brand itself.
If you decide to install the charging station at home yourself, we would like to give you a few tips.
First, always use an earth leakage circuit breaker with B characteristics, which is always lower than your main connection. Secondly, for this 7.4 kW charging station, use a 3x6mm2 YMVK cable for inside / in conduit or a 2x6mm2 YMVK-as ground cable for outside. 

Have you also checked whether you still have enough space in your fuse box? This is because the earth leakage circuit breaker takes up 4 modules, as does the power booster, so an expansion box is often needed.
For specific charging station installation instructions, please refer to the manual(s) below.
