I haven't looked at it since yesterday to see if it went to float but I will look at it in a little bit...
Oh yea, I seen the high voltage of the day at 15.2, I thought I got a pic of it but I can't find it...
It always get's up to 15.2 when it's Eq that's why I thought that was what it should finish at... But I see now that it's 14.8 I wonder why it's getting so high...

finding live solar data for you location could be informative, what's the location.
You 15:30 numbers indicate to me less sun!

It's the trees that's the problem.... I only get a clear 2.5 hours of clear unblocked sun this time of year... before that and after that it's just part sun/shade... But it's enough sun for the batteries to get up to 12.7 by 10:00am...
But you know I still go back to I've never had a problem at all with it going into float mode before. This all started when it went into Eq the last time and it hasn't floated since...
I really don't understand the change...
Plus I'll bet it's stuck in Eq again..... I will let you know in about an hour...

Ok I just went and looked and yes it's still Eq...... My batteries are at 12.9 already.... So it's not the batteries... I'm going to try something different today..... I'm going to check them today the same way as I did yesterday... But today I'm going to leave my load on it... I think it charges better with a load on it for some reason....
What I'm thinking is that it will keep the CC charging more instead of what it read yesterday in the end of the first hour when it was only reading 23.99a in full sun...
I will tell you why I think this later...
This is all an experiment.....

Ok Admin what are your thoughts so far?

if it resumes EQ, battery voltage should be ~14.8v while it accumulates addition time there, if PV voltage rises, current limited, battery voltage does not rise then reset and move on.
sulfation from repetitive undercharge. I'd find the battery makers recommendations for charging. if your temp corrected sg readings are correct your charging is correct.
14.8v is not much of a equalization charge!
I'm guessing you will find 10% charge recommendation or 60A, 14.8v charging with absorption time long enough for current to taper to 1A/100ah, a 30 day top charge and/or equalization of mid 15v or higher.

See that's what I was thinking also... That's why I thought it was 15.2 when it gets that high...
I will check what the batteries say it should be Eq at... They are Duracell Ultra 6V Deep Cycle. I looked some a while back with no luck.... I will try again..
Thanks again

Ok how do you think the CC is doing so far?? I figured pics are much better than me telling you how they are doing and it's also showing it in real time... Now that I'm doing this in depth way more than I've ever done it's very interesting and eye opening...
The charge controller seems to be performing fine. The 352W did seem lower but we're attributing that as only temporary and perhaps when a cloud was overhead. The values are very susceptible to change when it's not a clear day. -Renogy Team

Heck I seen it way lower than 352w when it was cloudy....
I wouldn't expect you to say anything other than there is nothing wrong with the CC Since it is a Renogy CC.... Update, There might not be anything wrong with it and I'm believing it was a glitch...
More to follow...

I'm not going to be able to do what I did yesterday because it's an over cast day here so I will try tomorrow....
Update..... Well it looks like it was just as well that I didn't record the data earlier...

Ok after searching for what Eq voltage of my batteries should be 14.8 isn't enough... Can it be changed? I'm not going to change anything until Renogy say's it's ok because I don't want to be blamed for anything...
Update, I would still like to know if I can change the Eq setting?

Ok I went down to the cabin a short while ago and low and behold it was floating even though it's been cloudy all day.... It was even floating when my fridge/inverter came on just like it has always done.... So it obviously doesn't matter if it has a load on it or not, I say it charges better with a load....
This proves it.... Pics are on the way soon... YEA....

Yes you're able to change your Equalization voltage. This depends on the battery manufacturers specifications. -Renogy Team
