Why does my Power One Aurora CCD Inverter show a Vbulk OV error?
The Vbulk OV error on your Power One Inverter indicates that the voltage at the bulk capacitors is too high. This can happen if the grid voltage is too high. Check that the grid voltage is compatible with the inverter's specifications, and if it's highly abnormal, contact your grid operator. If the grid voltage is normal, the alarm may be due to internal inverter faults.
What to do if my Power One Aurora CCD displays an 'Input OC' error?
The 'Input OC' error on your Power One Inverter means the input current is exceeding the overcurrent threshold. This could be due to sudden irradiance changes, which the inverter will automatically reset from. It may also be caused by a PV module incompatible with the inverter's input characteristics. Verify that the photovoltaic module specifications are compatible with the inverter. If the problem continues after checking these conditions, there may be an internal inverter fault.
