Solar power system power supply

System Overview
During the day, the solar panel generates photovoltaic current under the sunlight, which charges the battery under the control of the controller and provides power for the power-using equipment at the same time. If the sunlight resources are not good, the battery will discharge the stored power under the control of the controller to provide power for the power-using equipment. When the sunlight conditions meet the charging requirements, the controller controls the solar cell module to start a new round of charging.
As the battery has the function like reservoir water storage, the stored power will be accumulated gradually when there is sunlight. When it encounters cloudy and rainy days (ten consecutive days are allowed, this system is designed for 4 days), the stored power of the battery can be used for the system to continue working and still provide power steadily.
When encountering long-term continuous cloudy days, the solar power generation is insufficient and the battery voltage continues to drop to a set value, the system turns off the load output function to protect the battery. When the battery voltage rises to the set value, the system automatically resumes power supply.

System Working Principle
Solar power supply system mainly consists of solar panels, controllers, batteries, related load components, due to the specific use of different conditions, the product configuration will vary.
