It is much better not to have a problem than to make a mistake reading the data.
I shamefully should add that the days I was seeing that 300-600w were on partially overcast days
Well I feel a little ashamed, sorry to have everyone scrambling to get an answer with incomplete specs. I just checked each mppt.
Current reads 11:40 on a
semi-sunny day.
Mppt#1 12.5a@34v
Mppt#2 19.5a@32.4v
Mppt#3 10.6a@32.7v
Mppt#4 23.4a@29.8v
This about sums it up, I got so used to everything just working in unison as a whole. It's easy to forget that I set all this up and should have known to check individual components.Don't sweat it. You learned a couple things:
1) don't rely on a "summary" value when troubleshooting an issue that is comprised of multiple components.
2) PV production in overcast/partially overcast or shaded/partially shaded conditions is butt.
After I posted them cc numbers I did see a couple spikes that were peaking around 1.9kw. Maybe she just wanted a little attention after allNumbers in November can be impressive. Yesterday my #1 array achieved 7.1kWh from 1600W worth of panels. I saw a couple of times it was peaking at 1400W. Sunny and cold is just about ideal. It helped that my batteries were down to 20% and had plenty of room to accept power.
I did not mention the model.What shunt (sorry if I missed it)?
Not to mention the intentional spraying out artificial clouds from airplanes that creates a thick cloud cover quite a few times a monthFor the vast majority of MI Lake Michigan also throws a wrench in things with generating cloud cover. We frequently only get a few sunny days in November, December and into January. Things usually start to clear up towards the end of January when the lake finally gets cold enough and freezes over enough to quit throwing so much moisture into the air.
That sounds very useful, does it work independently? Meaning I don't need to go buy more blue things to get them readings?Just checking. Was hoping it was a Victron Smartshunt. One of the benefits of the Smartshunt is it logs the last 46 days of data, which gives you a more accurate history of performance.

Hi all its been a while. I have a 2.2kw array facing south. I tend to get 350ish and no more than 600ish watts during high production. Is that normal expectations?

Thank you, so 40% can be expected.I'm getting 2050 right now from a nominal 6 kw. It should peak at about 2500 watts. These panels are laying flat and a little dirty.
The sites I posted are extremely useful when you are trying to check or forecast production.
The smartshunt is a standalone device that tracks your battery's voltage, current and state of charge. When accessed through the bluetooth interface on your phone/tablet, it will report the last 46 days of values it tracks.
You've got to love Eggo recruiting new Smurfs by showing off Victron capabilities.Thank you!
I wanna get one of these shunty mcshunts now!![]()
Jip.My 14 kW of panels are producing 500 watts right now in the overcast, and have rarely done better for the last two days. November is a bad month here for solar generation.
40% can be expected.
