OK my little solar experts:
Just come back from holiday checked the Sunny Beam monitor for the solar production and no generation since the 7th Feb.
Looking in the event logs there is two or three events up toand between the end of Jan and the 1st of Feb with message 'Isolat. Resistance' but it still worked up to the 7th Feb.
On the 7th Feb there is 5 events with the message 'waiting f.D.C. start cond.' and then no output at all from then on.
So just been up on the roof for a wee nosey, found a connector that wasn't sheltered under the panels, opened it and found that it had a bit of surface corrosion on the connection pin, gave it a clean put it back together.
Went inside to the inverter restarted it still no generation and on the front green display the single line diagram is showing and open circuit on the AC side between the Inverter and the pylon picture.
Checked the MCB and RCD on it own dedicated consumer unit and all OK.
System details: Commissioned March 2011
10 Yingli 235-29b-1 Panels (Total of 2.35kW)
Sunny Boy 2500HF Inverter
So Sunny Boy has about a month on its 5 year Warranty.
Any ideas on what checks I should be doing next?
Cheers
