- Page 12 Chapter 6 Fault Diagnosis and Solution VFD500-PV solar pump inverter has 24 types of warning information and protection function. In case of abnormal fault,the protection function will be invoked, the inverter will stop output, and the faulty relay contact of the inverter will start, and the fault code will be displayed on the display panel of the inverter. Before consulting the service department, the user can perform self-check according to the prompts of this chapter, analyze the fault cause and find out solution.
