Last night I recorded last months output and since then the sunny beam is no longer showing or recording the output of the turbine. Even though it does detect the inverter, and as such is in wireless communication.

I am confused and guess I will have to contact SMA. I have always been impressed with SMA products that seem very well built and I am surprised at this fault. Fingers crossed it is easy to fix or I can get a replacement as the Sunny Beam and the aerial cost well over £200.
