TROUBLESHOOTING GUIDE --- INVERTERS --- APPLIES TO ALL MODELS
Troubleshooting for inverters In order to facilitate customers to inspect inverters on their own, in this article we will list common faults and fault analysis from the aspect of exterior indicators. Exterior indicators include a green light, a red light and a cooling fan. In the following we will analyze these faults from three indications.
Solution: 1) Check whether the input wiring of the device is short circuited; 2) Check whether the input power voltage is normal. The equipment should be connected to the matching DC voltage. (2) In the case of load, common faults are: A. When the power is turned on, the green light is on, the cooling fan runs, but the inverter does supply power after being connected. Analysis: The device may has been damaged or broken; Solution: Detect whether the device has broken down; Replace the device with others. B.
voltage or over voltage protection. Solution: 1) Check whether the device is short circuited; 2) Check whether the input power voltage is normal. The device should be connected to the matching DC voltage. When the power is on, after a period of normal work, the green light stays on, the fan runs and makes a noise. Analysis: The inverter works continuously, the temperature inside the shell rises. In order to cool down faster, the fan runs with higher speed, which leads to larger noise.
