Frequent fault alarm causes and solutions of inverters

In order to ensure that the inverter can operate stably in hot summer and reduce unnecessary unexpected shutdowns caused by improper maintenance or poor on-site operating environment, let's take a look at the countermeasures to solve the corresponding problems!


Reason 1: If the ambient temperature is too high, the temperature of the internal components of the inverter will be too high. In order to protect the internal circuit of the inverter, the inverter will report a high temperature fault and shut down.


Countermeasures: Reduce the temperature of the place where the inverter is located, such as adding air conditioning or fans and other forced cooling measures.


Reason 2: The inverter is poorly ventilated. If the air duct of the inverter itself is blocked or the air duct of the control cabinet is blocked, it will affect the heat dissipation inside the inverter and cause the inverter to overheat and alarm.


Countermeasures: Regularly inspect the inverter, remove the garbage in its air duct, and smooth the air duct.


Reason 3: The fan is blocked or damaged, and a large amount of heat accumulates inside the inverter and cannot be dissipated.


Countermeasures: Replace the fan.


Reason 4: When the inverter is overloaded, it will generate excessive current and a lot of heat, and sometimes the inverter will overheat and alarm.


Countermeasures: Reduce the load or increase the capacity of the inverter.
