Equalisation with EasySolar 48/5000/70 not working

I'm trying to perform an equalisation on my 16 Trojan T105 flooded cell batteries (2 banks of 8 x 6v in parallel). With batteries at 100% SOC, I pressed the equalisation start on the CCGX and although it read "starting..." nothing much happened - no bubbling of electrolyte. Do I need to tick the "Use equalization (tubular plate traction battery curve)" box in VE Config? Or is there something else I'm missing? I'm offgrid, no generator, 4kw of panels, with Victron EasySolar 48/5000/70-100 MPPT 150/100 Color Control.

Does it matter which device I initiate Equalization from?

My setup is Quattro 12/5000 - MPPT 150/70 - MPPT 100/30 - BMV-712 - Venus-GX

1. Does it make any difference which of the above three charging devices I initiate an Equalization from?

2. Do they all communicate and know that an equalization has been started so that the others don't interfere somehow?

Charging and equalising Victron AGM deep cycle batteries


I recently installed 2x110Ah victron AGM deep cycle batteries. Since my last battery bank (AGM but not victron) lasted no more than 2 years I want to be sure I make everything right with this one's

Charging parameters (285w solar panels) right now are

Absorption: 14,1v - 1hour

Float: 13,5v

I will like to know if this are ok and also if I would need to equalize them or not. I see very different information depending on battery manufacturer.

My solar chsrger let me program equalization schedule (every 30 days default), voltage and time

Thank you very much in advance

MPPT using periodic equalize function to give lithium a higher SOC

Other than increasing the voltage, is there anything about an equalize charge that would negatively impact a lithium battery? I regularly cycle my batteries between 20-80% but I'd like to charge them to 90-95% SOC occasionally and using this feature (and setting a 95% SOC voltage) while not technically equalizing/not damaging the bank would be great.

How do I increase equalisation time?

Hello Victron community,

This is my first post and my first off grid system which I am still getting used to.

I have a Multiplus 24/3000/50, CCGX and six Northstar Blue NSB210FT. Now I know there are issues using these AGM batteries which require equalisation for 16 hours every two weeks.

I have tried the first equalisation today by flicking the switch on the multi which worked and went into equalisation mode but it seems to switch back to float after about an hour.

Is there a setting to increase the time?

Also to get the Multi to start equalisation I use the MK3 dongle and enabled equalisation in the VE configure but it mentioned “tubular plate batteries”, not sure if my batteries are tubular plate of not?

firmware on my Multi is 1910142 so assume it has the old microprocessor and that I can’t initiate Equalisation via the mobile app?

Any help is appreciate.

Equalisation using a EasyPlus Compact 12/1600/70 and generator


I have an EasyPlus Compact 12/1600/70 installed on my narrowboat. I have not had a generator and so during winter have just charged my 4 x 6v 225AH Powerline T105s using the engine alternator. I want to do an equalization charge and have borrowed a friends generator. The EasyPlus manual explains how to do a forced equalisation, but the LEDs it refers to trigger the equalisation charge are not labelled the same as mine.

I've tried to trigger it on the basis that top to bottom they are the same, but I just get the 2nd led light constantly, which is not what the manual describes should happen when equalisation is triggered.

Anyone done this with a similar unit?

Equalisation Using Advanced Setting for Multi/Quattro in CCGX

Now that we can remotely trigger an equalisation charge with the CCGX (Start Equalisation button to the Multi/Quattro menu. See Device List -> Multi or Quattro -> Advanced)

Can anyone confirm what the settings are for this equalisation? Does it prompt you to set a voltage, current, charging time etc. and does it / can it also autostart the generator for this purpose? If not I assume it does the 1 or 2 hour equalisation at absorption voltage. My concern with testing this would be if it used the settings for tubular plate traction batteries as indicated in VE Configure. Hence why I'm hoping for an account from someone who has tested it!

Batterie Balancer and charging AGM slow discharge batteries on a 48V bank of 4x12V


Being new here and after searching the forum, I didn't find an answer and I am looking for some help. Thank you very much for your time and answers.

I am planning to wire in serial, 4 Hankook 12V - 65Ah to get to 48V in order to drive through an Alltrax SR 48300 controller a DC Motenergy ME0909 Motor ( 48V - 100 Amps ).
1) Is it a mandatory to use Battery Balancers (like BMV-702 or 712 ) in a serial AGM Battery Bank ( 4 x 12V ) as I have read somewhere that AGM batteries don’t need equalization ?
2 ) I understand these batteries balancers work when charging but do they work also when running the motor and therefore discharging the batteries ?
3) What is the best way and easy way to charge these batteries ? Is it by charging them one by one with for example a Blue Smart IP22 ( 12V ) or directly with a 48V charger like a MEC ( 48V Charger )

Thanks again

How to determine absorption/float/equalisation voltage

Hi guys

I recently bought myself a BlueSolar MPPT 150/35 CC to use in combination with a battery bank, consisting of 2x 6 V gel lead acid batteries (for golf carts): Golf Cart TAB Motion Gel Batteries (https://www.tab.si/index.php/industrial/display_smalltraction/4 ).

Now I ask myself the question how to determine the right determine absorption/float/equalisation voltage for this type of batteries. This link (https://chargetek.com/basic-information.html ) gives like a general rule of thumb for lead acid batteries: 2.25/2.4/2.55 V/cell ==> 13.5/14.4/15.3 V

I found there's a pre-installed program for forklift batteries: PzS tubular traction (1), 13.8/14.9/16.7 V. As forklift batteries are more or less similar to golf cart batteries and these numbers more or less look like the ones I found above, I intended to use this mode. However, I'm not quite sure if the batteries are tubular, and if that even matters.

Is there any other (experimental) way to determine these voltages?

Also, I read that it is not advisable to equalise gel batteries, is this right? Why not?

Thanks in advance!

Strange 100/30 MPPT behaviour in equalization

I have Bluesolar 100/30 and 150/70 (Easysolar)MPPTs connected to the same battery bank in 24V system. I have set both MPPTS to equalize in every 10 days. this is an offgrid installation. Noticed something strange with VRM and 100/30 charger:

- For some reason VRM does not show equalization in status graph, even though Voltage goes up indicating that equalization is actually happening.

-100/30 shows strange Bulk-OFF-Absortion state switching right after equalization. in one instance it ended to fault stage and was not able to recover from fault and I needed to disconnect and reconnect to get it working again.

150/70 seem to work fine, but not showing equalization in VRM

100/30 graphs:


150/70 graph (sorry that the panels are a bit misaligned) :


Any idea why the state does not show equalization in VRM or why 100/30 is behaving this way?

I won't be on site for a couple of weeks , but I would be happy to receive any feedback on this behaviour. Both MPPTs have the latest FWs loaded and have identical settings.

How do I equalize CPZS Cynetic 1160Ah batteries with an EasySolar 48/5000/70-100 MPPT150/100 Color Control without an external ugly generator? Bluetooth Dongle? No Battery settings display.

Hi folks!

I've had this 48V system running for 4 months now and it works like a charm. It's beautiful to feel like you don't depend on anyone. But that's not true ;). I would hit the equalize button every month until one day I realized that it was not doing it. My setup is in the title plus 24 panels at 230W each mounted in series and parallel as to achieve 100V~130V @ 5 KWH, DC of course. I've tried different firmware versions for the CCGX and updated all devices from VRM. Called my supplier and they said that: This system comes with equalization off by default and that I needed to buy the bluetooth dongle to do this, otherwise I need to have an external generator ( yuck ), in order to activate the equalization. Keep in mind that the "EasySolar" is worth 3,5K. OK. So I need this done NOW so I buy the bootooth wongle and when I head over to, settings/battery, nothing appears. I've tried with different phones and in some of them it detects the MPPT and CCGX and in others it only detects the CCGX, I don't know if that matters because the newer ohone detects the MPPT. I've worked very hard to make this system a reality in my life and I would greatly appreciate if someone with more knowledge that me could help me with this issue, since we all know that equalization is vital in keeping those babies in good health!

How to start equalise - Smart Solar MPPT?


I am trying to start a manual equalise on my flooded lead acid battery bank.

My off-grid system:

3 X Smart Solar MPPT (East,North & West arrays)

1 X Quattro 5kva 48v

1 X Venus GX

All devices are running the most recent firmware (as at 10/03/19)

With the three controllers in FLOAT, using the Victron Connect app on my phone, I start a manual equalise on each of the controllers. They all flash the blue and orange LEDs to show equalise mode is active, but the voltage never rises above the set absorption voltage.

The settings are the same on each of the controllers and are shown below.

Also below are the graphs showing the reported controller state (all three are the same) and also the reported system voltage and current. I tried to start the equalise at midday.

Any help or suggestions would be gratefully received.

Setting equalization current and termination on SmartSolar controllers.

So despite the absorption problem remaining unfixed by the last firmware update, I'm now trying to set my SmartSolar MPPT to correctly and automatically equalize, like my previous controller did.

The Victron manual states:

"The current is limited to 8% of the bulk current for the factory default

battery type, and to 25% of the bulk current for a user defined

battery type. The bulk current is the rated charger current unless

a lower maximum current setting has been chosen."

25% of 50A is 12.5A - much more than the specified 8a limit for my batteries. If the manual is correct, does this mean I have to hamstring my 50A controller to 32A, just to get the correct equalization limit??

Additionally, the manual also states:

"For all tubular plate batteries and the user defined battery type

automatic equalization ends after t = (absorption time)/2."

Again - ignoring for the moment that Victron controllers have horribly unreliable absorption times - this "absorption time/2" again doesn't match my batteries equalization time specs, so long as I try and also use their recommended absorb time

So am I understanding these settings correctly?

If so - who's idea was it to tie equalization limits to arbitrary %-ages of absorption??? It's a roundabout method that winds up meaning unless your batteries work specifically on Victrons ratios, you're force to have one parameter or the other incorrect, or both.

If these are controllable parameters (which they obviously are), why not make it a straightforward setting, so people can just set what they need and be done with it?

Length of equalization period

I would like to have more control over the equalization period and how often I can start it.

My 24 V lead-acid cells are sulphated. My battery manufacturer suggests an equalization period of 5 hours at 31.5-32.0 volts. Our Multiplus allows only a 1 hour eq period when started from CCGX. If I try to start another eq period immediately after an eq period has finished, the CCGX tells me that eq is "Starting ..." but does not actually start an eq cycle ie bulk and absorption LEDs are not flashing; battery volts oscillates between about 31.5 and 28 V.

Is there built in to the Multiplus software a limit as to how often you can perform an eq? And for how long? Is it possible to change these?

Is it possible to do this another way, by setting the absorption volts to 31.5 (my desired eq volts) and starting an ordinary charge?

Equalization not working

Multiplus inverter/charger 24/3000/70. I need to equalize Rolls 5000 24 V batteries. Multiplus says the batteries are floating. I start the generator manually, set the run time for 6 hours. From our CCGX I start the equalization process. The Multiplus shows that it is in the equalization process because the bulk and absorption LEDS are flashing alternately. The image shows the process starting at about 10.20. At about 12.45 the battery volts reaches absorption volts but instead of battery volts continuing to rise to about 30-31, eq volts, the charger switches to about 26.20, float volts. Specific gravity is still about 1.190.

Not sure what's going on. How can I get the eq to perform correctly?

Setting up different schedules of Equalisation with Lead acid batteries

I have a couple of customers who have Northstar AGM batteries on their small off grid systems. It seems from the Northstar data sheets they need equalisation every 2 weeks. Now we know the customer is never going to do the twiddly switch thing every two weeks (or even ever!), so was pleased to see the latest CCGX V2.20 firmware to include equalisation settings.

The only problem is, I cannot find anything pertaining to equalisation that I am able to initiate on the CCGX. Ticking the Equalisation box on VE Direct software is not quite enough as I'm unable to modify equalisation voltage or frequency of equalisation.

Any help greatly appreciated, as I am only able to equalise using a smart MPPT at the moment.

Multiplus not equalizing

We have Multiplus 2612431, CCGX 2.20 in an off-grid setup 24 V, with diesel generator backup. CCGX shows menu for starting equalization procedure. The equalization setting in the Multiplus is *not* checked, as in the attached image. I have set the battery type to Rolls (we have Rolls 5000 series), not shown in the image.

The generator is running, started manually for 6 hours, no stop conditions set. Multiplus shows we are in absorption state, battery volts about 28.4 V. I need to equalize the cells so I started the process from the CCGX. Multiplus changes state so that bulk and absorption LEDS are flashing alternately, battery volts quickly falls to about 27.6. I leave the system in this state, assuming that battery volts will rise to eq volts, return in 2 hours to find that the Multiplus shows float state. Specific gravity of cells has not changed.

I thought that in eq mode the cell voltage should rise to minimum of 30 V and remain there for a couple of hours at least.

1. Cell volts didn't rise to eq voltage, so what haven't I done?

2. Should the Multiplus eq checkbox be set?

3. Does the BMV SOC influence the equalization procedure in any way? I had previously (a couple of days before) set the BMV SOC to 100% (ie pressing + and - buttons at the same time) although the cells were obviously not at 100%, sg was too low to confirm this. I did this because BMV was not showing SOC at all and I wanted to get CCGX to log solar data. My intention was to refresh the BMV SOC value after eq had finished, when I would know (measure) that cells were at sg 1.265.
