OUTBACK MPPT 80 FLEXPOWER

[Bambinoruth714]

GOT 12 320 SOLAR PANELS , A SCHNEIDER 4840 AND 12 LITHIUM BATTERIES. MY BATTERIES ARE NOT CHARGING FROM THE SOLAR PANEL, I CAN CHARGED THEM FROM THE SCHNEIDER CHARGE MODE. ASSUMING SOMETHING IS DAMAGE, WHAT WOULD IT BE?

QUESTION 2. ASSUMING THAT IT IS THE OUTBACK AND THAT I WOULD HAVE TO BUY A NEW ONE, WHAT WOULD BE THE CORRECT SETTING ON THAT OUTBACK MPPT 80 AMP? AT THIS POINT THE MPPT OUTPUT IS 0 BUT THE IMPUT IS AROUND 126 WHEN SUNNY.
THANKS

Your pics show 38V in from solar. Solar needs to be at least battery voltage + 5V to charge.

How do you have your solar panels wired. Parallel, series? And if you have a breaker? Highly recommended.

Output should always read battery voltage or a little higher when charging. This implies the controller is not connected to the battery.

This implies the controller is not connected to the battery.

Or battery in protect mode (BMS disconnect).

Or battery in protect mode (BMS disconnect).

Only on discharge protect, and I think there would be a third question to the effect of, "why is my system completely shut down?"

What is your bulk charge settings?

ASSUMING SOMETHING IS DAMAGE, WHAT WOULD IT BE?

If you don’t have a fuse or breaker on the PV strings, and as it gets colder voltage could climb above 150v. The unit would be damaged.

You could call the Outback tech dept. 1-360-618-4363 ask for their imput. And see if the Outback needs to be sent in for warranty work.

So, in your previous post, you were never able to answer anyone's questions about how the panels were wired up or what voltage the battery is. So, I'm expecting similar results here.

In the other post, the charge controller's output voltage was 70+ volts, now it is basically 0 volts.

It is likely there is no connection between the Outback solar charge controller and batteries.
Check your fuses and breakers.

Your previous post showed 70+ volts on the battery side. Did you find that they were not correctly wired in series???
Something is fundamentally off here.
Take a picture that shows the layout of your batteries with all connections visible in the picture.

This!

Thank you, I wasnts sure how to carry the old thread over.

Thanks, I look over on the other thread and his Schneider is set to a 48 volts system. And his Outback was putting out 70 volts? Wow

 

[BKY2003]

I used to have an Outback 80 with my Schneider. If you do have to buy a new charge controller it might be better to consider the Schneider 60amp charge controller. It will communicate with the Schneider.

 

[BKY2003]

1st thing I would do is check the battery charge values on the Outback. Your battery has an overcharge protection and if you are not charging at the correct amount the battery should shut down. If you are using a 48 volt setup, which is what you have the Schneider set to. 70 volt from the Outback should shut the batteries down. https://www.talentcell.com/lifepo4-battery/12v-200ah/lf4330.html

WTF? I missed this. That should never be the case..

With multimeter:

Check voltage at battery terminals.
Check voltage at battery terminals on FM-80.
Compare to FM-80 displayed value.

Dude , you never acknowledge anyone who tries to help. This is your 3rd post on the same issue.

Several people have attempted to help you and have gone unanswered.

On the bright side... at least that one isn't ALL CAPS!

Awe man, we must have pissed them off. Now they're yelling for help but still it listening for responses. ?‍

If you are running a 48 volt battery setup, your absorption and float should not be above 58 volts. Myself I would set it to 56 volts. Also look at what your charging rates are on your Schneider.
