Plug-in solar is the fastest growing corner of DIY solar, and Jeffrey from There's A Trick For That is the guy who tests it hardest. He's back for round two, and the whole episode is plug-in solar: your questions, his real data, zero hype.
We cover the 120V vs 240V question (including the two-circuit trick that gets real 240V from two micro-inverters), whether plug-in solar can pair with a whole-home standby generator, battery pairing with portable power stations and raw LiFePO4, what happens when the grid goes down, anti-islanding and why your inverter must shut off, the best zero-export options on the market right now, and why plug-in solar costs what it costs.
Plus: Jeffrey walks through the plug-in solar laws sweeping the country (Utah first, roughly nine states with official laws now), the 1,200W continuous rule on a 15A circuit, why balcony solar kits get throttled, a buyer's warning on panel prices (the tariff-driven price floor and what to buy before December 4, 2026), and the sunshine report with weekly production totals from around the country and the world.
