But don't you loose efficiency at lower load factors.
Posted By: DamonHDGavin_A: is there anything specific to look out for on the SunnyBeam display (ie big all-caps warning saying FIRE ALERT!!! or whatever)? Or is it just a question of looking for low output.
Good tip about dusting the inverters. May have a look at mine tomorrow if I'm not too warm!

PS. James: never seen my inverters cut out (1100Wp nominal vs 1290Wp of panels), just limit at a tad higher than the rating.
Posted By: Gavin_A... mounted in a fully dust and vapour proof housing, with an internal fan...
Posted By: Gavin_Aaccording to aurora's UK technical guy at a trade think I was at last week, they reckon the design life of their inverters is 30 years, thought they advise people to expect to replace them once within the 25 year lifetime of the FIT's, that way some should be pleasantly surprised.
sounds like they're using some pretty hard wearing kit, and mounted in a fully dust and vapour proof housing, with an internal fan inside this housing to move heat away from the sensitive components to the heat sink, but with no dust getting in it should have a much longer lifespan or something.
i'm slightly sceptical, but they do have a decent rep for making hard wearing kit and have been doing this a long time, so maybe.
Posted By: MarkBennettHowever good they are, I can't see anything with a fan in lasting for 30 yrs even in a controlled environment.
Posted By: MegacyclesThe same inverter here, and the fan comes on under high output conditions, I think it switches on when the heatsink is>50'C.
Any air movement it generates appears to confined to inside the cabinet.
