Title: Classic 150 Equalize Issues
Post by: Resthome on December 30, 2014, 01:14:54 PM
boB

Since it looks like you are getting close to releasing another firmware update I wanted to bring this issue up again and ask if it has been address. See previous thread on issue.

http://midniteforum.com/index.php?topic=1891.15 (http://midniteforum.com/index.php?topic=1891.15)

boB, is this new firmware update going to take care of the issue of the Equalize function somehow getting into the Start Equalize function rather than defaulting back to the Stop Equalized when Equalize has finished. I just saw this again when I made a trip to the lake to check on things. I was changing the Rebulk value and when I hit enter to save the setting the controller jumped to Equalized when I went to the Equalize menu sure enough the Equalize Start option was showing. This has been brought up in the forums before and I believe you were aware of it but don't see anything in the new Readme file about it being fixed. Hopefully it can be included as with everything else Midnite has going on the firmware updates are getting few and far between.

Thanks John...

I am testing a unit right now up in the lab to see if this problem has been fixed.

It is kind of hard to find as it (of course) never happens here.  I think I saw it ONCE here
and all of the registers/settings and things looked completely normal.

Still looking.  The new firmware we are working on ~may~  make this better.

Not sure quite yet.  More testing is needed.

Thanks boB,

Just having it default to Equalize Stop after an Equalize cycle and maybe even after you hit the Start have it go back and stay at STOP as long as it allow the Equalized cycle to continue and requires an Enter to actual stop may help this. As it seems to occur when it completes a manual Equalize cycle and then stays in Equalize Start.  Then if you are hit Enter to save data to the Classic it seem to start the Equalize. Not sure what state it is in after a VMM. I'm 3 hours away from it so not much help.  I do use the LA a lot but I don't think it is coming from the LA at least in my last case it happened when I hit Enter to save a new Rebulk value. I also don't use Auto Equalize and I have never seen it Equalize when I am away from the unit. The daily data dump never shows an Equalize voltage anyway.

Just went back and read that old thread. Does it have to be in Equalize Start for the Auto Equalize to function, Is that true??  I would still want to see it default to STOP. And maybe have a different switch to start Auto Equalize. Per your quote "And, yes, the EQ menu ~should~ go back to EQ STOPPED.  Sorry...  I will look into this."

John, I'm not exactly sure what you asking here ?  I sort of am but some of you terminology is
not quite jiving with my brain.

For example,  STOP ?  Do you mean "EQ STOPPED" ?  Hit enter where ?

No, EQ STARTED (or is that START) does NOT need to be set in order for an Auto EQ to run.

Please excuse my old brain here.  Also I am not in front of a CC right now.

I don't have one to look at either, so when I said Stop I meant EQ STOPPED.
When I mentioned Enter I am referring to the button pressed to save setting to the Classic EPROM. I believe you have to press enter with the EQ STOP or EQ START to execute those functions. I believe that when it is left in EQ START that an Equalize cycle can be started accidentally while not in EQ menu. At least that is what I saw. Not sure if it can be duplicated or if these are single occurrences. But for me it has happened more that once. And if you don't notice the voltage climb you may not even realize it has happen unless you see the Equalize display is the Status menu.


So good Auto EQ is not controlled by the EQ START that means you could make the default be EQ STOP immediately after an Equalize cycle completes and also after a VMM.

Does this help? My old brain is probably older that yours.  :o

Well, let's see...  My brain is about 60 years old.  Is that older or younger ?

You don't have to press ENTER when going from EQ STOPPED to EQ START.
It just flips a software force flag to the Classic which resets it when it reads it.

I notice also that when an Auto EQ starts, that screen still says EQ STOPPED.

Should probably fix that too.

Younger, I got you beat, this month 68.

Hum... So this function is contrary to most other Classic setting that require the ENTER key to be pressed. Maybe I never waited long enough for it to read the Flag and just though I had to press enter. So if I set it to EQ STOP in the middle of an EQ cycle it will eventually stop the EQ cycle without doing anything else? Wish I had access to my Classic.

So the question of the day is how often is that flag read. If that is the case and it gets left in EQ START wouldn't it try to do another EQ cycle at least the next day when it reads the flag and finds it still in EQ START. Or is there some kind of logic applied once it reaches EQ DONE?

Wondering now if the ARST sets it to EQ STOP or just leaves it wherever it was set last?

I seem to remember it showing EQ START at various times and it was not in an EQ cycle. But I could be way off on that. I just know that at various time I have found it in the EQ START when I wasn't trying to start an EQ cycle and I have had it actually start an EQ cycle when I was not trying to.  Will have to really watch it next time we are there.

Happy birthday month !

OK, first...  ARST  ?  Oh, auto- restart.

Yes, when the Classic resets and starts from scratch, except for Auto-Reset (restart), a manual EQ will not
happen, even if the MNGP had been set for EQ STARTED.

The Classic does not actually "READ" the flags in that it does not  ask the MNGP what it should do.
The MNGP, when a flag is set in EQ or in TWEAKS, etc, actually reads the whole flags register,
modifies the flag word and writes it back.  The Classic itself does not have to sit there and read things.
Exception would be Follow-Me where it reads registers from its neighbor.

When the Classic resets or powers on, everything starts from zeros.  Then the first thing the Classic does it
to read the EEprom non-vomitable memory for stored values.  Manual EQ is not one of them since it doesn't
try a second day like Auto-EQ does.

In fact, right after you press the EQ START, the Classic reads this and then resets that force EQ flag.  That's
actually a FORCE EQ bit/flag.  The MNGP keeps the display at EQ start though.  It may need to look to make sure
that the MNGP reads things more often to reflect the state of the Classic but mostly you look at the
main status screen to see if the Classic has started the EQ.  It would say EQ MPPT first and when the
battery voltage gets to the EQ set point, it will say EQUALIZING.  I know you are not at the Classic
but using the Local App but next time you are there, try that and see if that works OK.

Yesterday,  found a Classic 150 charged system had initiated an EQ on its own.  Never do an AutoEQ.

It appears that the EQ may well have started while I was accessing the WBjr Setup>More page --  did the "Enter" function to save data,  and when returning to the main Status page,  noticed that the Classic output current was high,  and "EQ-MPPT" was displayed.   Went to the EQ page in the Charge menu,  and stopped the EQ.

Have only seen a self-initiated EQ on the other Classic 150 charged system here,  and then only once.

Never use the LA,  and always start and monitor the EQ process manually.

Am certain that the EQ process had just started,  as the Vbat was only about 2 volts above Vfloat,  where the CC has been almost all day,  as this was the third,  and last Skip Day before today's full recharge.

Am running 1849 FW,  and may take another run at trying to U/D the FW on the Classics here,  soon.

FWIW,  am glad that I was around to notice the EQ,  and it seems quite possible that some of my MNGP hand-waving must have started the EQ,  BUT,  have not been to the EQ page in the Charge menu for about two weeks.

Thanks,  Vic

Vic/boB

I've seen the same thing at least 2-3 times over the last year. And yes it always seems to be when I am in one of the menus on the Classic. Never have been able to pin down which one it was but the ENTER key may to be involved. I am definitely not in the Equalize Menu when it happens. And I think it has been in Float also but can't be positive. Wish I had the LA capturing the data when it happened but as luck would have it I did not. Noticed it because the fans usually come on and gets my attention. And like you Vic I haven't updated since 1849 but don't think boB made any changes to the way Equalize is suppose to operate in the manual mode. He was going to do something with the way that Equalize  Start/Stop button was being display/left and it's default position but I don't think that has been done. At least it's not in the change notices. Something is screwy with that flag that gets set to start the Equalize.  boB says that the Enter button is not required to start or stop a manual Equalize.

Always glad to know I am not the only one that experiences these issues. Thanks for the update Vic !

May get a few days at the lake this week that I can update and watch it for a few days. I'm trying to decide if I should make the trip this week as there is a chance of rain mid next week.  I'd like to see if the network disconnect issues have been resolved with the latest firmware. But I have a new laptop that has to get the com driver installed on it first.

Is it the 4160-4161 register and the ForceEqualizeF  - 0x00000080  bit that starts a new Equalize stage?  You seem to indicate previously that once the flag is set and Equalized is started that that bit gets reset to zero. Or does that bit stay set until the manual Equalize timer expires?

As soon as the flag has been read by the Classic, which should be milliseconds, it will be cleared.
However about the same time, the info flag will show that the EQ stage has been started.

I wish I knew if the start of these EQs happened when someone pressed any buttons in any MNGP menus.
If that was indeed the case, that would be a huge clue !

Title: Re: Classic 150 Equalize Issues
Post by: Vic on March 03, 2015, 12:36:25 AM
Hi boB,

Am almost certain that this most-recent self EQ WAS initiated by navigating into the WB Status Menu,  and perhaps the Enter that I performed,  to make certain that the WB Setup data was Saved.

The reason that I believe this is the case,  is that this was done fairly late in the day.  After Saving the setup data,  returned to the Main Status page ...  and noticed,  first,  that the CC output current was higher than it had been a minute or so prior,  AND that the CC Mode was EQ-MPPT.  The battery V was about 2 V above Vfloat,  and the CC output I was about 32 Amps.  This EQ could NOT have been going very long,  as the Vbatt  would have been higher than it was,  if that EQ had been initiated more than a minute or two prior to my returning to the Main Status page,  and noticing that the Classic was EQ-MPPTing.

Nothing absolutely absolute,  but  just circumstantial.   FWIW.  I am glad to see that this may be only initiated by human ditzing with the MNGP.   Much better than the possible case of a self-EQ happening randomly,  IMO.

Thanks,   Vic

Wonderful deductions, Watson.. I mean Vic.

That actually is a great clue I think.  Will look at code and ponder this with a possible idea.
At the moment this idea is just a gleam in my mind's eye but hopefully something useful
on this.  Has to do with bits changing when reading-writing-saving, etc.

I’ll second what Vic is saying about it seems to occur when buttons are being pushed in other menus and in my cases I’m just not sure which menu it was. Could have been the WBjr menus and I am pretty sure it has something to do with the Enter button being press to save settings.

So was interesting in what other flags would be in those same registers that would be reading, writing, or saving bits that somehow could trigger the Equalize flag. The current document on ModBus registers is way before the WBjr was added. Might be a clue as to what other menus may be suspect.  ;)

I think you have the general idea of what is happening, hopefully it will lead to some specific cause and a fix.

As Vic says it doesn’t look like it occurs unless you are at the Classic pushing buttons and that is a good thing.

Not sure this fits in here.  I observed what appears to be another bug related to EQ.  I decided to EQ today to bring up the gravity on a couple of low cells.  It was a bright sunny day with plenty of PV power to spare.  The inverter was running other loads during the EQ (EQ only drawing ~4-5 amps).  On termination of EQ (timer reaching 0:00), PV output from Classic just stopped.  I was watching the watt meter on Local Status App just go to zero and stay there.  All the while, the Whizbang monitor showed a negative amps reading indicating that the system was drawing (all) current from the batteries and nothing from the panels.  This persisted until I entered the configuration menu and pushed the Force Absorb button (have no idea why this might work, but it did).  Everything then returned to normal.  PV output back up to about 1100 watts or so.

Thought nothing of it, checked SG on batteries and decided to run EQ again.  Once again, while watching in LSA, when EQ timed out, watt output from PV (brilliant sunshine) at zero with inverter running and some light-moderate loads. Forced absorb again from LSA to resume normal operation.

Pilot error pehaps?  Any thoughts?
Title: Re: Classic 150 Equalize Issues
Post by: Vic on March 19, 2015, 12:09:48 AM
Hi Garret,

This is customary behavior,  at least on the CCs and batteries in use here.

After an Absorb stage,  or an EQ,  as the battery voltage descends to the compensated Float voltage,  there is no need for ANY PV power,  as the CC is waiting for the correct Float target voltage to be reached.

I would call this a Surface Charge effect.

From an EQ,  it can take a number of minutes for any PV power to be used,  depending upon the load on the batteries.   The only time that power is needed from the CC,  and therefore will look like current flowing to the batteries, is when it is needed to maintain a voltage regulating setpoint,  like Veq,  Vabs,  and Vfloat.  If the battery voltage is above the applicable setpoint,  the CC will just wait until its contribution is needed to maintain a set voltage.   IMO,   Vic
Title: Re: Classic 150 Equalize Issues
Post by: boB on March 19, 2015, 01:17:10 AM

Thanks Vic.  That is exactly what I was going to say except for the addition of the question of
what the battery voltage was after the EQ...  And/Or how long did he wait.

Also, the battery current will read negative some because of loads or even the
powering of the Classic itself.

I'm just impatient.  Guess it would take a minute or so for the voltage on a 400 Ah bank to decline from 31 to 26.2 V. 

Thanks, no worries.  I am a a little worried about one of my batteries, though.
Title: Re: Classic 150 Equalize Issues
Post by: boB on March 19, 2015, 03:21:01 PM

Garret, if you have a good amount of load on your batteries, the voltage WILL drop
quickly.  The more load, the faster that voltage will usually drop down to Float.

Time to bump this thread back to the top!

Hey boB did the MNGP manual Equalize Start/Stop ever get fixed to set the MNGP message back to the Stop Equalize setting after completing a manual Equalize cycle? What got me thinking about this is I was reading a blog from another fellow who stated he had his Classic start an Equalize cycle without ever asking it to do so. I have seen this along with at least Vic also commenting about it in this thread on the Midnite forum.

I know you have said that it just toggles a bit in a register but the strange ability of the Classic to start an Equalize without ever manually selecting it has me making sure it is in the Stop Equalize position before leaving it even if that flag bit is set back to 0.  I know you also said you don’t have to hit Enter to set this but that might make it more failsafe.  I pretty sure it takes messing around with other menus or buttons to trigger it rather than it just starting by itself. At least I hope that is the case.
I believe if the Equalize is started from the LA the MNGP display will stay in the Stop Equalize position (IIRC).
Anyway want to bring this up to see if there has been any progress.

John, I don't know if it has been fixed but mine started Equalizing by itself last week when I was messing around other menus.
Auto EQ counter seems to work now (FW2074), it is equalizing since yesterday the way I had set it last week (every 7 days for 2 days) as I wanted to be sure.

Yes there are a lot of confirmed cases of the EQ starting on its own, The only logical explanation I have is a memory leak. I asked if we could make 2 flags (1 in a seperate register by itself that gets set by "enter")

So the theory would be the EQ could not go unless both bits where high. This "should" fix it if it is a memory leak.

Hi boB,

Have never used the Local App,  the Classics here all have EQed on their own,  when manipulating some other Menu items (like Charger > Advanced settings).

So,  have been leaving EQ voltage set to Vabs (wish we could set Veq = Vflt),  and also set EQ Time to 00,  until this gets resolved.

Thanks for looking into these things that have been around for a while.

FWIW,   Vic
Title: Re: Classic 150 Equalize Issues
Post by: Resthome on December 05, 2015, 08:37:32 PM
I use both. But believe as Vic does that it only occurs when doing something in the MNGP. And I believe but can not be 100% sure that it happens after an Equalize has taken place using the Start Equalize. IIRC when doing it from the MNGP and the Equalize is complete with the Equalize Done flashing the setting still remains on Start Equalize it only goes to Stop Equalize if you select it on the MNGP.  boB check me on this but that is what I recall. At least when it started on it own and I went back to look at it that it what I think I found. But I could be all wrong on this as the memory isn't as good as it use to be.

I second Ryan's suggest, but at least somehow make sure it goes to The Stop Equalize function automatically when an Equalize cycle completes it time and require any new Equalize cycle to press Enter to start or something similar.

Hate to bring this up but it happened again after a manual Equalize Start. After completing the MNGP showed it was still displaying EQUAL START although it takes something to trigger it again when not desired it is usually looking and pushing buttons on the MNGP and NEVER GOING INTO the EQUALIZE menu. It could have been the TWEAK menu but not sure.

Please fix this !!  Just resetting the Equalize to EQUAL STOP after completing a full timed out Equalize I think would do the trick, but maybe not. I know it has been a bug for a long time. And I am using the latest firmware.

Hi John,

Personally,  always leave the EQ time set to 00:00,  and manually set the desired time when doing EQ,  and when done,  immediately set the time back to 00:00.

Yes this is a bit of a hassle,  and,  it needs to be done on each Classic on a system.

It would be nice to have this fixed.   Interactive bugs can be very difficult to find ...

Used to also set the EQ voltage to the lowest that it will go (equal to Vabs),  but this is not required,  as,  with the EQ time set to 00:00,  the Classic will NOT even start an EQ.  -  on its own,  or manually.

FWIW,   Good Luck,   Vic

Good suggestion.  But a pain to remember to set and reset a setting that you shouldn't have to. This problem has existed forever according to other posters. Maybe it isn't simple to set it to EQ STOP when the EQ timer ends. Obviously if set to EQ STOP it should not start an EQ process and I wouldn't have to set and reset the timers for EQ and new users wouldn't get tripped up by this behavior.

Thanks guys for your invaluable input.

This issue has been bumped to a very high level and is being worked on full time.

It is hard to catch it happen, especially when you are looking for it.

Thanks boB.

As always the best controllers and the best support on the planet.

Will add one thing;

Always monitor the EQ process,  often setting the EQ Time to a value that is longer than the period of adequate PV power to complete the EQ.

Every time that navigating around the Menus appeared to cause an EQ to initiate on its own,  I  had Stopped the EQ manually,  rather than the EQ timer having timed-out.

These two different reasons that the EQ terminated,  might be handled a bit differently in the Classic FW (am still at Classic FW 1849 on all Classics,  here).

FWIW.   73,   Thanks for all the efforts,  boB.    DE   Vic

In my case, I've never seen the EQ process start on it's own when I had the EQ STOP set in the menu. It always been when I let the manual EQ terminate on it's set time and the EQ START is left in the menu after terminating the EQ due to reaching it's set allotted time . It can be the same day or the next day after the Auto RST at midnight that when in other menus and using the buttons on the MNGP that triggers the EQ again. And it may. Be the Tweak menu and setting the voltage offset, but not sure.

Thanks Rest Home.

So, there does appear to be more of an issue it looks like when Follow-Me is enabled and connected.

This is good because it narrows things down a bit.  Without F-me, the very rare occurrence of EQ
will be a bit tougher but we'll crack it.

Thanks for the follow up boB.  In my case not using F-me, only have one controller on my system.

Hi boB,

Had only seen this issue before FollowMe was implemented.  Have not seen it since using FM,  because always do a manual EQ,  and ALWAYS leave EQ Time set to 00:00 at all other times.

Realize that for those who feel that they must use Auto EQ,  this work-around will not work.

Thank you very much for looking into this.   73  Vic

Making some progress here....

Interesting on EQ with no Follow Me with these software versions.

Thanks for this info.

Good to hear boB.  After a timed out manual EQ. Try going to the Tweak menu and adjust Battery voltage offset and hit enter. Don't know if it matters if it is a positive or a negative number. Try both and see if that is what is starting it. I'll try to watch it this weekend but won't have any internet to communicate my results back to you until after Sept 13.

Haven't seen any activity here for a while.   My forum access has been on and off though lately.  Something about DNS routing issues...

So, I have some software that can help track the EQs.  If you are having problems often enough to warrant trying this out, please PM me.

Thanks,
boB

Hi boB,

Thanks for working on this,  with ALL of the other Engineering projects needing time,  as well.

Will not ask for this new tracking software,  would not be a good tester,  as this is a very busy time of year,  getting ready for Winter.

For me,  not wanting or needing to do Auto EQ,  just leave EQ Time set to 00:00,   at ALL times,  except when doing the normal manual EQ,  and that does the trick.

Will need to update to the latest FW in all the Classics in use here,  very soon ...

Thanks!  73,   Vic

boB,

Unfortunately the wrong time of the year for me as my next time is to close up for the winter. I'll be glad to assist in the Spring if needed. I'll probably just do what Vic does for the winter months, even though I have never recorded it going into EQ while I am away during winter months.

Do you guys have Follow-Me enabled when the EQs happen ?

The fix that Ryan found is to simply disable Follow-Me on one Classic that you will call the "Master".
OR, disconnect the cable going from that Master TO the "slave" Classic.   Or both.

This appears to stop this from happening and Follow-Me still works.

boB, 

No follow me on my system. Just a single CL150.

FWIW (butting in here) - I have three Classic's in "Follow Me". I manually did a EQ charge this past weekend. One Classic I have designated as "Master"...which has the WBJr and temp sensor. When I hit EQ-Start...all three Classic's displayed "EQUALIZE" and worked. Using Firmware REV 2096. No issues.

Thanks, Chris

It would appear that any Follow-Me related unwanted EQs only seem to occur if the loop-back phone cable is connected.

In other words, just call one of the Classics the  "master" Classic and don't connect it to the last Classic at all...

Haven't heard of 3 or more Classics in Follow-Me having the unwanted EQ occur either.

If there are only two Classics in Follow-Me, just use one and only one cable for the "slave" to read the Master Classic.
Just arbitrarily appoint one Classic as Master as long as it is being read through the single  phone cable.

Of course, now that we have inserted the tattle-tale code, it appears to have maybe solved
any of these issues !  Murphy at work ?

Glad I watched Ryan's video on how to set them up properly. When I grow up someday...might rewire to a 48v system (battery's and new inverter).
