I have seen in the photos, although not perfect it is a install.
Do not start messing with the inverter, if it is not booting up (which it appears to be) then get the installer to "fiddle" with it.
I have posted before about building regs, the installer does not instruct them to visit, some installers can issue a certificate, and some can not, but you do not need building regs, just structural calculations, wind loading, and a part P certificate, and the lack of structural calculations may only cause a problem if you decide to sell the property.
Should you choose to get building regs, in my area the cost is £112, so it may be worth it for piece of mind, but it is not mandatory.
i always thought POWERONE boasted a low start up of 130volts
Is it in the loft?
Anyone? It hit 75 today!juniperzPV 3.920kW | Live Output
One question - the peak inverter temperature today was 70degC - that seems high (though what do I know?) - is that normal?
Anyone? It hit 75 today!
Thanks. I dropped a line to [email protected] earlier, so will see what they say.it'd certainly benefit from any additional ventilation you could put in to the loft, as well as moving lower in the loft space if possible.
those are the internal temperatures within the inverter, and I'm not entirely sure at what point it starts limiting the output, but those do seem a bit excessive to more, and will almost certainly reduce the lifespan of the inverter.
You have a point - strange. I don't think it is when the inverter is at its hottest (that seems to be an hour earlier) but it interesting that the Temperature takes a dip at the same time.@juniperz, Just looked at your pvoutput logs for the last few days - what's happeing at 3:05pm ?
Looks a nice curve, thoigh I wondered, does something create a shadow across the panels (roof onto garage? )or is is their a tree or telegraph pole?
Or is that when the inverter's at its hottest?
While I am rambling, anyone sending data to PVOutput.org using Aurora Monitor on a Raspberry Pi??
We'll we've got a couple of PI's here and that is one of the things we're going to be working on psot 1st August - do you kinow anyone whose done it yet?
I'd love to chat with them on the PI forums.
(RaspberryGeek is my son on the Raspberry Forums and I use his handle sometimes)
