Strange reset during the day

[boB]

I do have the classic reset itself every night,

You mean you have auto-restart set to ON in tweaks ?    It resets at 23:59 at night ?

Yes, boB, exactly what I meant.

Hi all

Any advance to solve this odd behaviour? I have a couple of customers with this "lights out & restart"

OK, do you know what their battery size and types of loads are ?

I am wondering if the battery voltage is maybe rising sharply above
the absorb or float set point.

Oh, has anyone caught the 3 Classic LEDs on the control board doing their reset "dance" when
the unit resets ?

One of them sent me a video (heavy, 8 Mb) I am uploading to youtube so you can check it out.

He is using these values:

BULK 2,4V/e
FLOAT 2,23 V/e
ECU 2,65 V/e

And his battery bank is a 12v set of TAB 5 TOPzS442 575C100

I have been told that during this reset the dial in the local APP goes to 0.

Thank you, is a wonderful machine, and regards to Robin.

Ryan says.....

"that is normal expected behavior. There is a bug in the newer code on the MNLP that causes it to basically reboot the MNLP for a lack of a better term. I have seen mine do that repeatedly. It is on Andrews list

Ryan"

But that does not explain the local app showing zero if that is happening exactly at this time.
However, when the Classic does its solar sweep, the power meter will go to zero for a moment.
Maybe that's it ?

Could be that indeed, so I´ll ask for a re-check or a video to see what triggers that.

My Classic reset not once but twice today.  Accumulated 2.3 kwh then back to zero, then .6 kwh, then back to zero, then another  .1 kwh to close out the day.  Time was correct and nothing else was out of the ordinary today. 

[boB]

OK, Wxboy, what is your Classic's software/firmware revision and date ?

To find it, press the STATUS button a few times until that information screen
comes up.

Also, what kind of router are you using ?

[Wxboy]

I believe it's version 1370 because it had an April date but I will confirm when I get home.  I have a Linksys router. 

[Wxboy]

Confirmed 1370 4/8.

[boB]

Confirmed 1370 4/8.

OK, that's new enough.  Have you seen it do this since then ?

How often has it reset during the day that you know of ?

Bob, I have some additional information to bring to the table.
Reading this thread reminded me that I hadn't had an alarm from mine for ages.
I thought it was simply because I'd got sick of it and turned them off... but on going back and reviewing my log data, day/time on which I've had a reset (determined by register 4131 having bit 7 set, eg, 0x3280) finishes thus:

18/Jul/2013 08:05:01
18/Jul/2013 09:00:01
18/Jul/2013 11:25:02
18/Jul/2013 13:15:00
18/Jul/2013 13:20:01
18/Jul/2013 15:20:02
19/Jul/2013 09:45:02
19/Jul/2013 10:25:00
19/Jul/2013 10:40:00
19/Jul/2013 12:25:00
19/Jul/2013 14:05:00
19/Jul/2013 15:00:01
20/Jul/2013 11:15:01
20/Jul/2013 15:20:00
22/Jul/2013 11:35:00

Several things from this.
1. It's only ever happened during the day, when there's at least SOME power from my PV.
2. I've sifted the log to find the number of resets each day, then sifted that for the number of days for each number of resets, and come up with:

Code Select Expand


Days   Resets
9          1
8          2
6          3
5          4
2          5
2          6
3          7

(Remember, I've only had the device online for a short time!)

3. And this is the really interesting fact:  it hasn't had a SINGLE RESET since it broke (recall we chatted in IRC at length, something went screwy, we removed R57 and got it limping along again....)

Well, the thing is: it is still connected to the ethernet, using the same cable, router etc that it's always had. (never unplugged it). It is still polled by my newmodbus utility every 5 minutes like it always has. It is still connected to the same battery bank. It still has the same firmware version.

The ONLY changes I am aware of are:
1. Changed settings from the standard solar mode, to "legacy" mode per your instructions.
2. Reduced PV input from 3.6KW to about 400W

Anything there give you anything to go on?

[boB]

VERY interesting stats, Ross !  Thank you !

I don't think that R57 has anything to do with it.

>>>2. Reduced PV input from 3.6KW to about 400W

I would try adding back some more power to it and see if it starts resetting again.

I'll have to do a bunch of rewiring to put the classic back in full production after I moved it back to the flexmax-80, so that'll have to wait.

What would be perhaps more interesting would be to find someone who has the same problem and see if they can make it go away (and come back) on demand, by changing to legacy mode!
