> In Germany [...] Just plug Anker’s inverter directly into any standard home power socket to feed energy back to your appliances with any excess diverted to the battery. That's legal? In the US, at least for generators, it is illegal in most jurisdictions to do that. You have to add a transfer switch that disconnects your house from the grid before you supply non-grid power to your house wiring. That's so people's generators won't energize the lines that the linesmen are trying to fix during a power outage.
