How Does a Portable Solar Generator Work?
The working principle of a portable solar generator mainly relies on the process of converting solar energy into electrical energy. The following is its detailed working principle:
1. Solar energy capture and conversion
Solar panel: This is the core component of a portable solar generator and is responsible for capturing sunlight. When sunlight shines on the semiconductor p-n junction, new hole-electron pairs are formed and separated under the action of the p-n junction electric field, thereby generating current, which is the photoelectric effect. Solar panels convert sunlight directly into DC power through this effect.

2. Power storage and control
(1) Charge controller: Also known as a regulator, its main function is to regulate the DC power received from the solar panel to ensure that the battery can be charged safely and efficiently. The charge controller can prevent the battery from overcharging, thereby extending the battery life.
(2) Rechargeable battery: Stores the electrical energy captured by the solar panel and regulated by the charge controller. These batteries are usually lithium batteries or AGM batteries, which have the characteristics of high energy density and long life.
3. Power conversion and output
Inverter: Converts the DC power stored in the battery into AC power for use in most household appliances and electronic devices. The inverter is a key component to ensure that the portable solar generator can power a variety of devices.
In summary, the portable solar generator captures solar energy through solar panels, which is regulated by the charge controller and stored in the battery, and finally converted by the inverter into AC power for use. In this process, not only the clean and renewable use of energy is achieved, but also a convenient and safe power supply solution is provided for people.
