This circuit is a charger for single-cell lithium (Li-Ion) and Polymer (LiPo) batteries. It can sources energy from DC jack connectors (two different dimensions), USB-C and solar panel. It uses MCP73871 which has the peculiarity to smartly adjust the current sank, making it ideal for solar-powered applications, where the available energy could be really scarce and high-varying over time.
SCLD stands for Solar Charger LED Driver
This is a combination of a typical TP4056 lithium battery charger with a Joule Thief adjusted to power a common 12V LED strip. I have tested this with 30cm LED strip (18 LEDs) with a single 18650 Lithium battery (capacity around 1700mAh) and it lasted around 8 hours. I have also tested it with a 3m LED strip (180 LEDs) which is offering a lot of light with...

*Sorry for my following english language (En français plus bas)*
- Energy self-sufficient, solar panel charge battery with TP4056 and systeme is low-power managment
- Check luminosity with solar panel and open or close the door (no RTC)
- Geared-Motor AC is drived with specific H MOSFET bridge IC
