Plug in Solar question
Plug in solar is getting more popular in the US because it works in Europe. But I have a question on how well it really works.
Europe is 230v in the home. Everything in the home is 230v, including the Plug In solar. All loads in the house see the solar power across the line.
US is different. We use 120v with loads balanced across both phases to Neutral, and 240v for the bigger loads. Plug in Solar is 120v, so its only across one phase to neutral. Does any load on the other phase benefit from the Plug In Solar? What about the 240v AC unit? Its phase to phase so I would think it would benefit somewhat.
Personally, I think its a scam. Excess power is fed back to the grid but you get nothing for it! The power company just sells it to the neighborhood. You only benefit when the fridge, space heater, or HVAC is running.
