Hi asdex,

Great that you have gotten some of those AGMs on-line.

As you probably know,  cool battery temperature (as measured by the Battery Temp Sensor -- BTS  --  that you are using,  we hope),  will reduce Capacity,  and increase Float voltage.   If your batteries are a bit cool,  and you are using the BTS,  this could explain both the  Capacity and Vfloat.

The Remaining Capacity,  is the Temperature compensated Capacity that the battery has presently,  based on the Parameters that you set in the WBjr Setup.

Did you set the "WBRST"  to "YES"  in the Tweaks > more > more > more > more screen?  This should set the SOC to 100% the moment that the Classic makes ITS transition to Float.

Also,  when you mentioned that the Classic charge stage was Float,  it was NOT in Float MPPT was it?

More Later,  Thanks Vic

Hi Vic, thanks for your reply. Yes it was about 10 degC and I am using the battery temperature sensor.
I'll have to check the WBRST when I'm there next in a couple of weeks. I'll try and remember and I have pictures of most screens.
The Float was just float as in the picture. This picture was at 97%
I see in my pictures I have absorb time at 2 hours and efficiency at 95%
I couldn't get internet last time there but should have it sorted for next time.

Try leaving space between batts. 4 airflow. Also recommend firmware update:-)

OK asdex,

Hope that you can get the Internet working at your cabin.

Would strongly suggest that you have reasonably reliable internet access at the site before doing a Firmware Update on the Classic,  especially if the computer you are using for the Update has not previously successfully done a previous UD.  With the recent Win 10 Updater,  some of this may have changed,  but,  still having access to this Forum may be very helpful,  if the update does not go perfectly smoothly.

Have not used it,  but the Local App has the ability to remember all of your customized settings in the Classic,  and return them to the Classic after the required VMM (Reset Classic & Restore Factory Defaults).

Good luck,    Vic

Hi, I'm able to head up to our cabin this weekend. I won't do the update at this stage though until I have the battery system working ok.
I had a reply from Haze who say to increase the absorb voltage to 29.4 to charge them faster and also to equalize them monthly.
I don't think you normally equalize AGM batteries but they said to do this as these type I have are actually designed for UPS use.
I can't complain as they were $1 each and are 3 years in to their 12 year lifespan(on paper anyway).
I'll check the other settings and do a download of the settings list as well.I have used the local app when plugged into the Classic directly but haven't got it running over Wifi yet.

Azdex, how far is it between the CC and the WiFi router?  I think if it is close enough you might be able to connect the CC to the router and then WiFi to the computer , rather than using a bridge device ...

Hi, the router is about a meter away. I can configure it as a wireless bridge too. I haven't spent alot of time on it as the app works ok when plugged in but its not as comfortable as sitting inside monitoring.

Hi, the batteries are working alot better now. In the morning they are at about 91% SOC. I expected this as I have gone down 100AH in capacity. I connected my laptop and downloaded the log file as well.
I have the absorb voltage at 29.4v and float at 27.6v. They are going to 100% capacity now.
I don't think it will be a problem running to 91% as it is the middle of winter. I may replace my 12v Air-X wind generator with a 24v one which will help.
I am hoping to keep away from having four parallel strings in my battery bank.

Hi asdex,

Thanks for the Log File info.

Never look at this stuff,   BUT,  the way I read it,  looks that your EQ voltage is quite high for AGM batteries ...  IIRC 31.4  or 31.6 V.   Do you want an EQ at this high a voltage?

At the very least,  would set the EQ Time from 60 minutes,  to 00 minutes.

Looks like a cool climate   batteries around 6 degrees C ...

Thanks,  Vic

Hi, yes it is high and I didn't think you should equalise AGM batteries anyway but advice from Haze says to do this and voltage is below:

Graham
It is normally done at constant current and unlimited voltage but if you have to set a voltage limit - 15.8V
Regards
Nick

I have equalising off at the moment and will do it on manual each month as advised. The difference here is I'm using UPS batteries in a cycling situation which isn't normally done.

I have just bought an Air-X 400w wind generator and any advice with incorporating it into the system would be helpful. I can adjust the cut out on it but it's going to clash with the absorb voltage.
