A solar setup you plug into a normal wall outlet, with no permits and no utility approval, is the kind of thing that is illegal almost everywhere in the United States. In a video from Jasonoid, the creator shows one running legally on his deck in Utah, made possible by a state law called HB340. The heart of the system is an EcoFlow Stream micro inverter rated at 1,200 watts, fed by 750 watts of solar panels and plugged into a standard 120-volt outlet. According to the video, the law lets Utah residents back-feed up to 1,200 watts into the grid without permits, as long as the equipment is UL-listed and installed properly. The inverter itself costs about 300 dollars.
Plug-in solar like this is common in parts of Europe, where small balcony systems that feed a household outlet have been sold for years, but it has been effectively blocked in most of the US by interconnection rules that require utility sign-off and professional installation. That is what makes Utah's HB340 notable, and why the video stresses it: the creator says Utah is, as far as he knows, the only US state that currently lets a micro inverter back-feed the grid this way without permits. He also points to a different path for everyone else, describing newer devices that use a smart shunt on a home's main wires to sense consumption and offset it without ever exporting to the grid, which sidesteps interconnection rules but tends to cost more. There is an important buyer catch the video is clear about. This is not net metering. The system does not earn credits or roll the meter backward. It only zeroes out consumption while the sun is producing more than the house is using, which for a typical base load of 400 to 500 watts it can do during daylight.
The practical details matter here. The video stresses that you need a smart meter, which can tell which direction power is flowing; with an older digital meter, back-fed power can register as extra consumption and actually raise your bill. The creator also recounts that his utility, Rocky Mountain Power, flagged his account when it detected back-feeding, and a representative visited before confirming the setup complied with the law and clearing the flag. On the hardware, the video describes six 125-watt bifacial panels strapped to a deck railing and wired in parallel, with the DC output routed under the deck through a disconnect into the inverter, and the EcoFlow app handling remote monitoring. The inverter has three inputs good for 450 watts each, for a 1,200-watt ceiling, and the creator notes panels need a starting voltage between 20 and 60 volts, so most standard residential panels will fit. He even mentions briefly experimenting with feeding the inverter from a 48-volt battery. The footage was shot near the winter solstice, the worst case for output, and he expects far better numbers in summer when daylight hours are longer. During filming he shows the system back-feeding around 430 watts, enough to read zero at the meter for a stretch of the day.
Bottom line: For Utah homeowners with a sunny balcony or deck, this is one of the cheapest ways to start trimming a power bill, and the roughly 300-dollar inverter makes the math easy. Just go in clear-eyed: you need a smart meter, you get no net-metering credit, and the savings are capped at offsetting what you use in real time. The bigger story is regulatory. If load-following devices that never export to the grid take off, this kind of plug-in solar could spread well beyond Utah. For now, it is a Utah-only experiment worth watching.
