My brother asked me to design a simple system that would power a cpap for his friend plus charging their phones and running some lights.
Okay so this system has three simple parts. First is a single 100w solar panel. This is the one that I use on my camper. (Though I use six of them with a much larger system.)
This adapter allows you to connect normal solar panel MC-4 connectors to the input port on the Jackery. This means you can use normal solar panels instead of their expensive panels that come with an 8mm port.
The battery is a Jackery 500 which is perfectly matched for the 100 watt solar panel. This should charge from 0% to 100% in one day
