Simple Solar Power Bank Circuit Diagram

Without going into great detail i thought that i would illustrate a very simple and basic solar power system diagram.

Simple solar power bank circuit diagram. Power bank circuit diagram. You could utilize 3 100 watt panels listed below. A charge controller 5v boost converter li ion battery a battery charge controller circuit. This block diagram describes about the power bank design.

As we can see its fairly easy to make a power bank with li ion battery tp4056 module and a boost converter. The function of the battery charge controller circuit is to control the state of charge of any battery according to its capacity and rated voltage. 4 using two li ion cells without complex circuit. Although the designs look very straightforward it demands the use of two 3 7v cells in series for the proposed power bank operations.

Block diagram of a power bank is consist of 3 main units as shown in the above image. A basic solar power system. This power bank circuit can be built with easily available breakout board. The term 18650 cell is due to the cell dimension it is cylindrical in shape with 18mm diameter and height of 65mm.

This solar power bank circuit provides dc power through usb connector and has 1 watt white led for lighting needs. The three simple power bank circuit designs shown below utilizes minimum number of components and can be built by any new hobbyist within seconds. First one is 5v 500ma solar panel then li ion battery charger breakout board.
