PV Inverter
Photovoltaic controller is an automatic control device used in solar power generation systems to control the charging of multiple solar cell arrays to batteries and the power supply of batteries to solar inverter loads.
The photovoltaic controller adopts high-speed CPU microprocessor and high-precision A/D analog-to-digital converter, and is a microcomputer data acquisition and monitoring control system. It can quickly and real-time collect the current working status of the photovoltaic system, obtain the working information of the PV station at any time, and accumulate detailed historical data of the PV station, providing accurate and sufficient basis for evaluating the rationality of PV system design and verifying the reliability of system component quality.
In addition, the photovoltaic controller also has a serial communication data transmission function, which can centrally manage and remotely control multiple photovoltaic system substations. With the reduction of the external dimensions of photovoltaic inverters and the increase of single machine power, the requirements for heat dissipation design are becoming increasingly high. Designers must comprehensively consider the cooling effect, protection, installability, maintainability, and economic cost of the inverter cooling system. Among them, single machine power is an important basis for designing heat dissipation schemes.
Inverter cooling technologies include natural cooling, forced air cooling, liquid cooling, and phase change cooling. Various forms of working principles and characteristics. Heat dissipation technologies include natural cooling, forced air cooling, liquid cooling, phase change cooling, etc., which are mainly selected based on the power of the inverter. The forced air cooling system is simpler, easier to implement, and more reliable than the liquid cooling system. Therefore, in the photovoltaic inverter power industry, forced air cooling is the preferred method for heat dissipation, followed by natural cooling, liquid cooling and other heat dissipation methods.
