Do you think Mr. Li or Wang or Chan can turn off your solar or wind power generation anywhere in the world?

It turns out that yes. In solar panels made in China, fraudulent equipment was found that provides alternative communication channels that can be used for remote control or shutdown of energy systems. This was reported by INTERESTING ENGINEERING May 14 2025.

By connecting your hybrid inverter to WiFi, all your data is automatically transferred to a friendly country that will never turn off your generation and is in no way involved in the shutdown of an entire country like Spain. Earlier I wrote that your country can ban your generation, now the risks have increased at least twice.
If your inverter has WiFi, I strongly recommend removing it.
