A Solar-Powered Mini UPS is a compact, eco-friendly backup power system that uses solar energy to charge its batteries and provide uninterrupted power to small devices during electricity outages. This project is ideal for powering Wi-Fi routers, LED lights, CCTV cameras, and small electronics in areas with frequent power cuts. It ensures continuous operation without relying on the main power grid.

Parts Used:

1. Solar Panel (10W–50W, depending on load)
2. Charge Controller (PWM or MPPT)
3. Rechargeable Battery (Lead-acid or Li-ion)
4. Inverter Circuit (if AC output required)
5. DC-DC Converter (for voltage regulation)
6. Switching Circuit (to shift between solar and battery power)
7. Enclosure Box (for safety and portability)
