Impossible results

[davidwf15]

Can anyone explain what is going on here....
Several times recently
I have seen impossibly high solar production spikes like these
I am also seeing barely any solar production on slightly overcast days
We have 6.6kWP and a KH7 inverter

Your kit is fine, unless it has entered the Punk years of it's life.

I have seen it before with my kit, where the data being stored on the fox servers looked like a Punk haircut, or hedgehog if you prefer. Nothing is wrong, just a glitch in the sending/storing of the data (not sure which really.)

OK thank you....doesnt seem right though..it never did it before but its now doing it all the time

Need either a few more forum opinions, or you may have to reach out to installer/Fox to get them to check over system.
The height of the spikes at near 10kW or PV is a tad extreme I will admit, but I have seen the spiky results similar before.

Somebody reported similar a few weeks back, the kit was fine but the load data was spikey - Fox calculate the load figure from other sensors, and I have a suspicion that datalogger update timing (or even firmware) may play a significant role in this.
I know it feels like the old TV repairmans trick, but a restart will change the timing window and it would be interesting to see if it ‘resolves’ the logging.

nope, inverter restarted and its still the same
