OV-BUS Fault

The OV-BUS fault is caused by over voltage on the DC busbar INTERNAL to the inverter. This can be caused by several reasons, but they are all internal failures of the inverter. They cannot be repaired by the customer. 


  1. Power Board is broken
  2. Relays are damaged
  3. Connections between EMI board and Power board are not connected


The inverter will require an RMA
