alt Hacker NewsI am not very well versed on this topic but I believe the balcony solar products market one of their safety features as "anti-islanding protection". Personally I wonder what happens if multiple balcony solar systems are connected... can each still tell when the grid is down since the other power source is active?

Hobestly solving these sorts of problems could be a huge business.

people put few kW worth of micro-inverters and it is fine so I imagine that is figured out problem...
question is whether the ones allowed for sale implement it well and are tested for it

Unless there's so much generating capacity available that they can power the entire connected grid, no.
Consider 100 homes on a power line network and the breaker trips. They probably draw 50kW on average, more if it's hot or cold and AC is on. Unless there's enough power generation available to power that entire load, voltage will drop and any halfway reasonable hardware should give up.
