Small, “balcony solar” units hold particular appeal for renters who cannot install rooftop panels and could take portable units with them should they move.
dadarobot@lemmy.mlhow is plug in hybrid safe with a male plug? strikes me as a “suicide cord” type situation (male to male extension cords people want if they accidentally string christmas lights backwards).
does the system wait for electricity to flow in before it flows out? do you only connect a small amount of panels per plug so the voltage isnt dangerous? do you just have to be very careful with the plugs? do you plug in the inverter to the wall before connecting the panels?
im not trying to imply that they are dangerous, im generally curious how this works.

does that even work in a split-phase system?

Solar microinverters are usually for single phase (sync to 230 VAC 50 Hz) and the balkonkraftwerk ones are plugged in into wall sockets. Of course, if there are multiple phases in a household you can plug in an solar microinverter output into a socket that’s on a different phase. They turn off within some 20 ms or less, so this is safe if mains losing power.
There are regular solar inverters that can deal with three phases, and also some which can deal with battery charging and can operate in insular mode and are black start capable.

i’m mostly thinking of how it works when production is larger than demand in the local circuit. phase imbalances are a bigger deal when the phases are 180° out of sync.
