These are technically kinda crazy, because they use a normal schuko plug (with male pins) to output power. It allows loading the circuit with a higher total amp

These are technically kinda crazy, because they use a normal schuko plug (with male pins) to output power. It allows loading the circuit with a higher total ampacity than the circuit breaker protecting the wiring at the distribution panel. It takes a very specific set of regulations to make these legal, and those don't apply elsewhere in Europe. https://www.vde.com/de/fnn/themen/tar/tar-niederspannung/erzeugungsanlagen-steckdose https://www.vde.com/de/fnn/themen/tar/tar-niederspannung/erz... https://tukes.fi/-/ala-kayta-pistorasiaan-kytkettavaa-aurinkopaneelia https://tukes.fi/-/ala-kayta-pistorasiaan-kytkettavaa-aurink...
