Dear all
3 months ago I had professionally (fully acredited) instalation of 10 sanyo ht n240se10 PV panels on my roof. they feed into a Sunnyboy 2000hf inverter. From the very begining the output from the inverter has been very poor. When the electrician contacted SMA they took all the output figures + agreed with him that the power from the panels was fine. They said that it must be a faulty inverter. After waiting to get a replacement a new sunnyboy (same model) was fitted 3 weeks ago. Still the power generated has never gone above 750w (+that v briefly) and the total generated in almost 4 weeks is 29kwh (about 1/3 what I believe I should be getting) at this time of year given my annual estimate of 2160 kwh. The electrician says he is foxed + the desiegner says he has rechecked all the spec + there should be no problem-whilst obviously it is their problem to short out has anyone come across this before?

other figures on my cert are voc 327.2v + isc 1.4A
