6 kinds of protection functions of photovoltaic inverters, how many do you know?
- 2024/11/23
As an important part of solar power generation system, photovoltaic inverter has a variety of protection functions, including overvoltage protection, overcurrent protection, short circuit protection, overtemperature protection, overload protection and ground fault protection. These protection functions can ensure that the inverter works stably and reliably during operation, and improve the safety and reliability of the system.
Overvoltage protection means that when the input voltage of the inverter exceeds the set value, the inverter will immediately disconnect the circuit to prevent damage to the inverter or other equipment. Overcurrent protection means that when the inverter output current exceeds the rated value, the inverter will automatically disconnect the circuit to prevent damage to circuit components or other equipment.
Short circuit protection means that when a short circuit occurs at the output end of the inverter, the inverter will immediately disconnect the circuit to prevent damage to circuit components or fire. Overtemperature protection means that when the internal temperature of the inverter exceeds the set value, the inverter will automatically stop running to prevent damage to the inverter or cause other safety problems.
Overload protection means that when the output power of the inverter exceeds the rated value, the inverter will automatically reduce the output power to prevent overload damage to the inverter or other equipment. Ground fault protection means that when the equipment has a ground fault, the inverter will automatically disconnect the circuit to protect the safety of equipment and personnel.
In general, the protection function of photovoltaic inverters is very important, which can effectively protect the safety of equipment and personnel and improve the reliability and stability of the system. Therefore, when purchasing and installing photovoltaic inverters, we must pay attention to whether the protection function of the inverter is perfect to ensure the normal operation and use of the system.
