Does anybody know how they synchronize the AC waveform on these plug-in things?
I have been operating on the understanding that you can smash DC sources together but not AC. It sounds like I could parallel inverters with this tech. That would be cool.
Power electronics have become cheap enough that inverters, including ones that synchronize to an existing network, are quite easy to manufacture even for home use. And yes, running multiple such in parallel is possible, and actually supported by some of the "balcony PV"-inverters sold in Germany, not least to sneakily circumvent the 800W regulatory limit. You can even mix balcony PV with multiple home battery units, if you want. Of course one still needs to take care that the cabling won't be overloaded, and especially the battery units are still so expensive that they need to last way longer than their warranty time before you can break even.
