A plug-in balcony solar system for uncertain times.

Title reads like at ad, but this is a new way to reach energy independence. I actually have a small EcoFlow device and it’s pretty good for the price.

I hope this tech can be made available in the US soon.

    Same for the EU.

    Solar inverters also need to follow the grid frequency

      They don’t follow the grid frequency because the EU or US regulations require it, they follow the grid frequency because physics demands it.

            I think I get that, thanks. So an Island grid is less stable and could cause itself damage if two microinverters say are trying to sync up to each other vs a beefy, stable main grid?

            So how does a backup battery system work when islanded? Typically also at 52Hz?

            Or can it go into a 60Hz beefy mode?

            It would be nice to get all the little island solar inverters working when the grid goes down!

              I’m guessing the commenter above is in the EU and operating at 50Hz normally, so running at 60Hz wouldn’t be a great idea. A backup battery and such operate in the same way when islanding.

                  IIRC some inverters are able to sync up with alternative power sources, but the documentation is extremely limited and seems to be reserved mostly for large-scale systems. I know my Solaredge system has slowly been implementing using both at the same time, but the documentation is pretty unclear as to how this works. I know at the very least it’ll allow you to use a 2-wire start to kick a standalone generator on when the batteries are low, but don’t know much else about how it’s currently set up
