The heavy rains in Northern Europe last month caused catastrophic floods in several countries. [Daniel Jedecke] During the flood, he was on a mission in North Rhine-Westphalia, Germany, and witnessed the loss firsthand.He was shocked by the lack of emergency power and set out to design a Simple and portable power pack.
[Daniel] I hope his system is as simple as possible, maintenance-free, and inexpensive. He bypassed traditional solutions, such as gasoline-fueled generators or advanced chemical battery packs. Instead, he chose ordinary car batteries-they are easy to buy in a pinch, and he found a used 45 Ah battery in the basement. In order to maintain the portability of the system, he decided to use a single 80 W monocrystalline solar panel with a smart battery charge controller. In addition to +12 VDC output, the inverter also provides standard (Germany) 240 VAC.
Except for the panels, the whole thing is installed in a ready-made toolbox, and the parts are fixed on a custom-made wooden frame.We believe [Daniel]Achieved the goal: made of standard materials, durable, without excessive maintenance, portable, and provide DC and AC output for daily use. As early as 2015, we wrote about emergency battery packs using rechargeable drill batteries. In the event of a power outage or disaster, are you ready for an emergency power pack?
