Night Generation!

haha

I'm currently generating 370W!

must be from the reflection of the snow

I bet that reading is on the OWL. Just shows how inaccurate and rubbish they are at reading low levels when there is a lot of 'noise' on the mains. If your generation meter registers anything during the night (LED flashing) I'd be most surprised.

http://www.pvoutput.org/liveteam.jsp?tid=110 - this is a list of people in the 'UK team' - I was surprised when I happened to look at this at 6AM, and see several people reporting nonzero amounts.
Mostly by only 30-40W.

I'm disappointed that ours only generate during the day and not by moonlight! Once at 0 they stay that way until the next morning but that is monitored via Sunny Explorer not an energy monitor.

Hi

This is more likely something to do with the time of the data collection .... Quite often SunnyExplorer displays cumulative Energy for the day after generation has stopped which changes at night ... we tend to see this showing up as a difference between the cumulative-to-date reading and the (PrevCUM+daily production) ... I've never checked it out but guess that the correct daily production is logged and written to the history file as NewCUM-PrevCUM at sometime around midnight in order to balance the books .... you can often see the effect of an imbalance between the metered daily production stats and the cumulative generation on an inverter if you change the clocktime whilst generating, (so, if necessary , best to do this whilst it's dark .... )

There's at least one occasion where Sunny Explorer has shown a graphical 'spike' of a few Watts generated during the night which isn't there in the data record and doesn't appear on the graph if viewed a few days later either ....
