At present, few people in Europe are worried about rising energy prices, and even if all the related problems disappear overnight, we will still see some price increases. As a hacker, you can evaluate the power-hungry devices in your home and perhaps do something about it. So, [Peter] installed some solar panels on the roof, but couldn't find a convenient way to legally connect them to the public grid, or at least to the 220V grid. In parallel, connect the low-voltage neutral to the grid and place a few devices on top.
48V uses a high enough voltage to be efficient, easy to use DC devices, legally protected from problems, and generally compatible with solar panel installations. Since then, he's been placing devices like laptops, chargers, and lights on DC rails instead of plugging them into an outlet, and his home infrastructure, including a rack full of Raspberry Pi boards, has been running 24 hours a day. , 7 days a week from V. 48 Lane. In cloudy weather, there is backup power from a conventional air conditioner, and in the event of a power outage, two solid LiFePO4 batteries will power all connected 48-volt devices for up to two and a half days.
In the first two months, the facility produced 115 kWh, which is a significant contribution to the Hackers' Energy Freedom Project, and the blog is full of details for all your motivational needs. This project is a reminder that low voltage DC projects are a viable option locally - we've seen experimental projects at hacker camp that are pretty decent, but if you want you can do a little CC build. UPS. I just want to get a wet toe. Perhaps we will get a socket for this network soon.
