My inverter went down with a fault code 9 at 22:30 on Friday 14 August. Since then I have had 11 9's 30 fault code 57, 3 fault code 64 and a fault code 194. What can I do to solve this problem.

What inverter do you have ?
There are a number of different fault codes there, the 9 indicates a grid voltage problem (outside of safety limits), and some of the faults relate to dc bus overvolts and battery overvolts - Best place to start would be to check you have the latest version of firmware on your inverter and batteries.
