A solar photovoltaic power system consists of solar cell arrays, controllers, battery banks, inverters, and other components.
The solar cell array is the core and most important part of a solar power system, working to convert solar energy into electrical energy, store it in a battery bank, or power the load.
One of the core components of a photovoltaic power system, the controller typically performs the following functions:
Signaling detection of light
The status and parameters of various devices and components in the photovoltaic power system are monitored, and physical quantities such as input voltage, charging current, output voltage, output current, and battery temperature are detected.
Optimal charging time control
Based on the current solar energy resource situation and battery status, the optimal charging method is determined to achieve efficient and rapid charging.
Battery discharge management
The discharge process of the battery bank is managed, such as load control automatic on-off switching, soft start, and protection against voltage drop errors when the load is connected.
Equipment protection
To protect against overvoltage caused by inverter faults and overcurrent caused by load short circuits in the control system.
Operation status indication
The operating status and fault information of the photovoltaic solar power system are indicated through indicators, displays, and other methods.
The battery bank stores the electrical energy generated by the solar cell array when exposed to sunlight and discharges it to the load at any time.
The basic requirements for battery banks include a low automatic discharge rate, long service life, strong discharge capability, high charging efficiency, low maintenance or maintenance-free, wide operating temperature range, and low price.
An inverter is a device that converts DC power generated by a photovoltaic power system into AC power. The photovoltaic inverter is an important component of a photovoltaic system that maintains balance and can be used in conjunction with typical AC power supply equipment.
