Comment on Easy-to-use solar panels are coming, but utilities are trying to delay them
ExcessShiv@lemmy.dbzer0.com 7 hours agoOh you can buy off grid inverters (or inverters capable of “island mode”). But they are required to be able to automatically disconnect from grid, even if they are never going to be connected to a grid. You can’t buy solar inverters without this for the exact reason that you can connect them to grid.

Again, it doesn’t matter what inverter you buy, they can’t tell the difference between off grid and grid off. So if it shuts off when it doesn’t detect voltage, then it won’t work off grid. Which makes it sound like you’re saying off-grid inverters are illegal.

They detect incoming frequency, not voltage. And yes, they absolutely detect the difference, I have one, it works exactly like this.

How do you detect the frequency of voltage that doesn’t exist?

I mean…if there is no grid frequency detected it automatically breaks connection between the house and the grid and keeps supplying the house from the panels and batteries. When it detects grid frequency again it reconnects the house to grid. It’s a fairly simple concept.

So you do realize that this is exactly how HV wire detectors work right lol… You hold up a wire (or there’s a wire in the wall) carrying high voltage, and the wand will pick up the EM Field.
