The functional protection parameters of the inverter mainly include overvoltage protection, low voltage protection, overload protection, short circuit protection, overheating protection, etc. These parameters are set to ensure that the inverter can be protected in time under abnormal conditions to prevent equipment damage and safety hazards.
1. Overvoltage protection: When the DC input voltage exceeds the maximum value allowed by the inverter, the inverter will stop working to prevent equipment damage caused by excessive voltage.
2. Low voltage protection: When the DC input voltage lower than the minimumvalue allowed by the inverter, the inverter will enter the protection state to prevent the battery from over-discharging and damaging the battery.
3. Overload protection: When the output current of the inverter exceeds the set protection value, the inverter will automatically stop working or reduce the output power to prevent equipment damage caused by overload. The value of overload protection is usually higher than the maximum allowable current of the inverter, it depends on the design and application scenarios of the inverter.
4. Short circuit protection: When a short circuit occurs at the output end of the inverter, the inverter will stop working immediately to prevent equipment damage and safety hazards caused by the short circuit. Short circuit protection is usually implemented by detecting whether the output current exceeds the set protection value.
5. Overheating protection: When the internal temperature of the inverter exceeds the set protection value, the inverter will automatically stop working or reduce the output power to prevent equipment damage caused by overheating.
In addition to the above common protection functions, the inverter may also have other protection functions, such as lightning protection, reverse polarity protection, etc. The settings of these protection functions can effectively ensure the safe operation of the inverter and improve the stability and reliability of the entire system. In choosingWhen using an inverter, these functional protection parameters should be comprehensively considered based on actual needs and application scenarios to select an appropriate inverter.
