This is interesting, set all aside temps, how its constructed, the power cycle is what changed it. Sounds like the inverter(s) were stuck in a finish charge, this may be a programming issue, is it available on line to watch remotely, has it done that again, next day?

Fun times programming

Hey Now All Wise ones!

 

An of gird client emailed yesterday that his Solark had been accepting only 350 watts of a 4KW input from the array. The modules are Q-cell 325 watt 2 strings of 7 modules.

 

Sunrise, full sun, no clouds so no edge of cloud effect, negative temps @ -6˚F, he waited all day with no improvement or change in the charge rate consistent 350watts input & then same thing next morning. Negative temps & full sun & 350watts solar input.

 

He turned the Solark off for 10 minutes & then turned it back on & 4KW charge input returned. The Solark did not turn off or deliver any alarm or warning.

 

My initial thought was over-voltage spike, we designed for a -25˚F scenario & 110 PSF snow load. Beefy! 

 

I did not ask if it was windy additionally. Could this contribute to a colder array temp? I have always been of the impression that wind chill did not affect metal or glass that it has to do with moisture being driven off.

 

Thoughts & suggestions?
