Lead acid battery Equalisation on Outback FM60 or FM80 MPPT

- How to program an equalisation directly on the Outback regulators without the system remote control. Personally I find it simpler than using the MATE.

Thank you for the EFFECTIVE, CLEAR video, explanations. The Outback Webinars are difficult to follow and not clear at all. I learned more in 3 minutes than they put out in over an hour. Moreover, I notice that you respond to viewers questions and comments.
Thank you for the compliment :-) I am affraid that just now my response time has been lagging some
@@JimSkau Where did you get those batteries with the clear cases from??? those are cool!
@@RoofTopPigeon The type is called OPZs 2V cells and they're an industry standard so fairly common and easy to obtain. We're now moving over to lithium batteries. After a few years of research, we now have a reasonable ratio between price and quality on this technology. Makes life a lot easier as a solar user :-)
looks simple but will probably need to watch it 10 times and take notes...not used to doing it
thanks
The man is a legend of solar!
Nice battery bank ! 2v cells ?
@2 fm80 @12 6volt Trojan t105 @ 24 100 watt mono renogy panels @ 2 1000 aims pure sine wave @ 1 3000 watt magnum @ 1 Onan 6500nh powerplant . been off grid for 7 years
Hi will like to now what votes need set my battery are fools s 480 6v
Good morning I have a question first though love the video and your batteries what kind are they. Secondly I live completely off grid I have a 48 volt system so I have to use 6 volt batteries. At the moment I have 16 interstate 6 volt batteries and within the next 2 months I am gonna upgrade my battery bank can you recommend a couple of batteries or maybe some like what you have thanks
Hi, I would recommend you to go for LiFePo4 batteries by now. Make sure your regulator and Inverter is capable of programming charge and cut off voltages, though.
Hi Jo, If you're changing battery bank, you might want to look into lithium batteries. They kind of out compete lead acid by now. The type of cells in the video is the OPZs type stationary 2V cells
Hi, I have litium batteries, how do I disable the equalization completely?
Hi Markus. You go to the EQ menu and set the AUTO option to 0 days. This is factory default by the way so probably already set.
Hi how now volt I need to set I have rolls s460 battery 6v each total 8 and have 48 volt . Thanks help is going be 1 time do ,this
Lead acid battery EQ voltages are 12V/15 ---24V/30---48V/60
A Rolls 48V battery equalization BEGINS at 60V.
Remeber the EQ is a trade off (un compromiso) The process will wear your batteries but the gain from an equal acid density and "cleaner" lead plates makes the trade worth doing.
New batteries usually don't need EQ for the first year or so. Specific gravity differences between the cells tells you when you need to do this. Also if you have had a very deep discharge make an EQ.
Never never never discharge batteries bellow 50% I prefer to keep to a 65% lower limit.
Begin at 60V and one hour. Check your specific gravity on all cells and look for differences. Go another hour if you still have one or more cells showing lower density.
As your batteries gets older you can increase both voltage and time. Last resort for Rolls batteries is as high as 64V in 3 hour increments but now you need t be present and look for increased temeperature as well. If the cells feels feverish stop and give the eq a rest. Never do EQ in summer. EQ is best done in ambient temperatures of less than 20C
Haw does this apply for AGM batteries?
Honestly, I don't know mate. We never work with AGM batteries so I could give you wrong advise. Absorbent glass mat (AGM) are of a diferent architecture, get documentation from the battery manufacturer before you try anything.
Try reading through this en.wikipedia.org/wiki/VRLA_battery
Arizona Wind & solar forum is another good place to ask.
Agm batteries do not need equalization
WHAT BATTERIES IS THAT!
It is 2V open vented lead acid cells
@@JimSkau I found them. Do those ones you have still work?
@@JimSkau I think he ment want brand of battery? I want to know too
Those are the weirdest flooded batteries I have ever seen.
It's just 2V cells normally called OpZs and a number showing the amp hours.... Their time is dwindling fast by now. We have moved onto lithium, which is a revelation and a relief for users and installers alike. No more equalizing and topping up cells :-)
@@JimSkau thank you for enlightening me. Good luck with lithium. Hope they last way longer than lead acid battery anxiety cells 😂
15 views!! that's criminal when you see the crap on YT getting thousands. Try removing the url from the title, Google's strange algorithms might detect this as spam and knock it back
Thanks for your comment. I will try your suggestion although the intent of this video was for us to link our clients directly to the instructions. Views in my world is looking out over the Sierra Nevada :-)
@@JimSkau great video ..a quick question , how much watts did you have on that 12v system ?
@@fazimabdool6437 thanks Fazim, Good question but it's actually not that important. It is the higher voltage level (above 15V) that makes them gas and bubble. Obviously your batteries needs a decent charge to get to tat point but once it is reached it takes very little energy or Watts to keep the process going. The system in question has about 800W of peak power but the actual wattage during the video was only about 90W to maintain the EQ voltage
@@JimSkau ahh I see , thanks for the info ...one of the primary reason for my question is that I have intentions of adding another panel to my system to take it to 900 watts , I would have gone to 24 v but my inverter is already 12v and my battery configuration is set for 12v ( 600ah ) ...the thing is I was wondering if 900 w on an outback 80 fm is kinda pushing the limits too far or would it be able to cope with the amperage ? Have you had any problems with your 12v system running at 800 w ?
@@fazimabdool6437 You're well within the FM80 limit on 900W so go ahead. Two reasons for this. When Outback says its an 80Amp charger they mean it and it will go even higher but that is beyond the point. If you look for the amperage you'll have to divide the system voltage into the watts desired...here it's 900W/12V=75Amp The truth is that you hardly ever see 12V on a 12V system (i sincerely hope that) you are most likely running up over 13V during the charge process (you should hit 14.5 ideally for your type battery) and that's allowed in the equation as well so now you have 900W/13V=69 Amp in fact even an FM60 would work with that wattage. It would get hot and loose a little in efficiency on the rare occasion that your panels are running full throttle.
