Trojan batteries

vas said:
no idea, as I said when new version of s/w is out, as soon as I try to run the app (and there is internet connection on my mobile) it finds it and comes up with an update dialog. I guess you do have internet on board and you are allowing applications on your mobile to be updated?
try maybe installing the app in a new device/mobile and see what happens!
App version looks at least 1yr old

Are you sure there a newer one then v1.5 as I can't find one

Vic, if you have Blue solar MMPT regulators they dont have temperature compensation. If you are in the Med and your battery box is at a considerably different temperature to the regulator, you are likely to have been charging at the wrong voltage. The new Smart solar MPPT solves this problem. The old firmware was also likely to under charge your batteries by sending the batteries to float before the batteries were fully charged. I suspect the problem with short battery life is not the batteries but the charging regime

Hi Tim I can't find a newer fireware so I think mine is up to date .
I can't believe the batteries been under chage because I keep a very close eye on them and when the mppt show there on float the current is 3 or below amps , if you take inconsiderate what working at the time in which case the batteries must be fully charge .
Safe trip back

He has a Smart Solar MPPT controller and the firmware is up to date.

v1.5 is the current controller firmware, but VAS it talking about the app' on your phone. What version is that, it's certainly different to mine and mine is definitely up to date at version 5.25

It does sound like you have latest firmware then Vic. What is your typical absorption time and bulk time added together in hours? What is your typical peak Watts to the batteries? The bulk and absorption period should be circa 6 or 7 hours on a typical day. Are you using Expert mode on the software? The Expert mode allows you to have an adaptive absorption mode instead of a fixed time based absorption mode
 
As Paul just confirmed the fireware for the control is v1.5 which is what I have see photo
The setting are as Trojan suggests in their data sheet see photo .
Would you not agree that if the batteries refuse to accept more then 3 A that they are fully charge ?

I think you are correct that the app' is out of date though Vas. There are a number of missing features on Vics app', such as expert mode and adaptive absorption.

Paul I had deleted the app and re down load it and it's the same app

Victron connect v5.25

Abs and bluk time depending on the day and what we used over time panels stop charging and starting charging again,
Anything between 8 and 12 hours

All looks good to me Vic.
Are you using expert mode settings?

I check all the setting in the begin not only Trojan data sheet by I made other enquiry with people who had tHe same batteries .
I know some have suggested they may not had been charged correct but
Current drop to 3A must be a sure way to know the batteries are fully charge and on float , That's how I understand it to Ben .
They not been short of water at any time or run too low .
Which don't leave much , maybe the batteries it was a Friday night job .
I had email Trojan and the one line email I got back said , I need to get them check by a master Trojan dealer , I replied asking them The nearest one to me in Sicily , the replies was they don't deal with customers in Europe .

The one UK dealer I did speak too basically said it could be because I haven't deep discharge them . When Trojan data sheet clearly says their batteries don't have a memory so it doesn't matter how much or little you use them .
NOW dont get me weong , I'm not rubbish them many say they had a good run with them , but clearly there some thing wrong with the once I had .
Hoping I can get through till Nov then I decide what to change them too .

3A going into the batteries at bulk voltage of 14. 6v so sounds close to full charge, 3A going in at float voltage then no, they ain't.
It's usually not the batteries unfortunately. Just to confirm, what time of day does the regulator usually frop down to float voltage of 13.something V ?

Typical day roughly see photo .
If I look at the history every day as long it's a day it gone into float max V 14.66/14.70

The app' that you downloaded (v5.25) is not the same as the one you posted a pic of in post #27 Vic, this one is newer. With the newer app' you can now select the "Expert mode". I'd do that and use adaptive absorption.

Just an obervation Vic, your bulk and absorption period is very long. If you have sufficient charge going in the to the batteries you would expect the combined bulk and absorption period to be circa 6 or 7 hrs. If you are not using expert mode as well my guess is you have been undercharging the batteries. Have you used a hydrometer at all to check the batteries charge state? Do you run an equalisation cycle periodically?

Paul I have the App on both my iPad and my sumsung if I delete the sumsung or iPad app and re download it , it loads the same app again .
Any suggestion
