Common Faults of Inverters and Their Solutions
Many homes and offices with power shortages or erratic power have solar inverters to ensure that essential appliances continue to be powered throughout the day. Like other machines, solar inverters sometimes fail. If you have an understanding of some common inverter faults and their solutions, it will save you a lot of trouble. Below we introduce three common failures of solar inverters and their solutions.
1. The inverter cannot be started.
Inverter failure to start is one of the most common faults. Failure of the power switch, disconnection of the battery, loose battery terminals, low battery power, reverse connection of the positive and negative poles of the battery, etc., will cause the inverter to fail to start. To solve this problem, it is necessary to prescribe the right medicine. If the power switch is faulty, it must be sent to a service center for repair. The battery is low, and it is recommended that you charge it for a few hours. Batteries have loose terminals, check them for corrosion and clean them well before securing them securely.
2. The backup time is shortened.
The reason for this may be excessive power consumption, at which point the extra load must be removed. In addition to this, insufficient battery capacity will also lead to shorter backup time. Increasing the battery capacity is a good solution.
3. The alarm keeps going off.
When the inverter's alarm keeps beeping, the possible causes are inverter overload, abnormal voltage, battery failure, and some because the cooling fan is stuck. If it is overloaded, please disconnect all additional loads. If the problem still cannot be solved, the inverter must be handed over to professional maintenance personnel. If the battery is under voltage, please charge the battery and reduce the load. If the battery is over-voltage, please contact the inverter supplier. Every solar inverter has a cooling fan that needs to be running as long as the unit is running. If the cooling fan cannot maintain enough temperature to work safely, the inverter will automatically shut down or an audible alarm will sound. Likewise, if the fan gets stuck for some reason and cannot cool the inverter, the unit will sound an alarm notifying you that the unit needs to be shut down.
