Not the parent.
It's likely a safety issue in the case of grid-connected solar installations. These panels are designed to send excess electricity to the grid, and if the grid is down, the utility needs to make sure that busted cables are not carrying electricity... for the safety of the repairmen.

- nibbleshifter 4y agoPreventing backfeeding during an outage isn't a hard problem, technically speaking...
- zo1 4y agoIt's a default feature in grid tied inverters from what I've been told.
- sgerenser 4y agoYes, but the most common way they do this is just by shutting down completely and not accepting any input from the solar panels. You need to move up to more expensive models that support “islanding” to be able to use solar power while the grid is down. For some reason it appears that this type of inverter isn’t legal in Israel?
