Power unit not ready
Do you mean no_Pu error?
Reason for error = 24Vdc is being applied to the control card but the mains voltage is not being applied to the power stage.
Who do i contact when i have and error code d27 on my solar inveter?
Sadly, I think you will find that a Sharp warranty does not cover this type of fault. It is attributed to either a lightning strike or a power surge. Perhaps your utility company could advise you particularly if you have date and time of failure. The inverter will likely have to be replaced and you should confirm that the replacement is legal in your area as some units have beeni banned in wide geographic areas. You might have to try another brand. Other than your utility company, Sharp, or maybe Infinigi, I am not sure who might give you advice. Possibly you might contact the Department of Energy (if in the US) about a grid tied inverter or NREL. Here is information from EVACO:
