Re: Unusual daily production value

I have been offline so missed your last reply. I have had a very stable few days with the data so at the moment it is looking good. The unit is a PV1-3.6-OUTD running firmware c.0.2.2 I have been trying to see if others have noticed similar events but so far no luck. What I have noticed also your pr...

Re: Unusual daily production value

I agree with you about is it worth it :) e.g last night at the close I had about a 3kw spike live data about 11w and this morning another about 3kw spike and 5min later normal readings. The production effect was nil. For some reason the other day it effected production. What I have been doing is che...

Re: Unusual daily production value

I understand that. It is no doubt at startup and sometimes at close I have noticed an unusual bump in data, and at times throughout the day depending on cloud cover then bright sun other spikes occur, but in all cases we could expect a limit in those values. It is the Aurora causing this, I just now...

Re: Unusual daily production value

I had not really seen this before either. I had on some occasions seen a small spike at the start of each day but at the time initial startup (set to start when inverter starts) but only of say 100 to 200 watts. i put it down to initial start up probable data loss etc, rest of days all OK. So never ...

Unusual daily production value

Using aurora 1.8.6 and solar 1.6.0. Had an event today that had me producing almost 9 Mega watts of power. Checked csv files (daily production) and found that the first recorded value for the day was incorrect. For information in the daily csv file the last entry for each time stamp is the running t...
