[solved] there really is a important error in the SOC%

[zoneblue]

In the weekend i added the soc register (4373) to blackbox. I can confirm that SOC is broken with the following combination of settings:
- days between bulk=5
- reset net Ah on charged=yes

In the chart below the stg column is the raw decimal charge state register. Upon waking for the first time this morning, both netah and soc reset.

I don't quite understand your spread sheet and why it appears to go to 100% at 6:27:55  but I do
see why it resets to 100%  when you have days between bulk/absorb set to skip days.  (non 0)

The problem is that would happen would be, every new day that it is NOT supposed
to go to Bulk/Absorb, it will go to Float.  It would do a force-float and that is where the SOC = 100%.
I think I have just fixed this.

So, NOW, it only resets to 100% when  it goes from Absorb to Float because of a full battery.
There is also now a modbus Force Flag that allows one to force the SOC to 100%


Regarding  Cybermaus's question about run-time since reset, yes there is.  It is called UpTime and
is in seconds and is at modbus register addresses  4348 (Low) and  4349  (High)   or registers
4349 and 4350.

I can verify what boB is saying about the reset. I just got back from the lake. Sure which I had an internet connection while I was there (water is too low to get a good signal). My SOC resetting to 100% was being caused by the Classic going to resting and the RFR was 104 - Watchdog Timer. I talked to Matthew at MidNite before I left the lake but he was not aware of the new update. I could not pin down what was causing the Classic to reboot but I suspect as boB said it had something to do with the log data. Did capture the Debug settings, don't know what they mean or if they may be useful.

[Halfcrazy]

Hm SOC is undefined that's a new one? I have not seen that one before. boB will have to comment but the new code has one fix for the classic rebooting when the logs are being read and written at the same time.

Here is the one with the debug readings after one of the RFR - 104 codes.

Do they mean anything?

Not sure what was going on with that undefined SOC. This was in Absorb and it is okay here. Not sure if it go confused with one of the resets.

Bob, do you want the good news or the bad news?

The good news is that with 1795, SOC doesnt reset in the morning.
The bad news is that it also doesnt come out of sleep in the morning:

Ive tried setting days betweeen bulk to 0, force float, and bully reboot, still RFR 36.

I will try a lite VMM in case that makes a diff, shortly, and failing further advice, revert to 1779.

OK, good.  I know what the RFR = 36 is.

An Over-Battery-Temperature "feature" was added and so it will need
a Vulcan Mind Meld to set the register.    Register 4262  or address 4261
is the reference temperature.  Your Classic is probably sitting at a very
low number right now.  If you could set it to, say,  1700  (170.0 deg. C)
that should fix it.

I'm not sure if your newer MNGP will VMM it properly or not.  The hardware
VMM, placing the two outside jumpers on within 1 minute of re-boot of the
Classic will also fix that but will of course reset all of your settings.

Coming out with another MNGP revision which will also allow you to manually
set the battery SOC to 100%  in the WB Jr. ---  MORE menu by holding down
the LEFT ARROW key and the ENTER key.  Coming right up.

Is it possible to get an updated list of current RFR codes for the latest firmware? I know there have been some additions.

[zoneblue]

Great, hardware VMM fixed it.  Will put days betw bulk back in and let you know how it goes.

Thanks!

BTW could we have 1dp on the SOC register, looks kinda cranky.

Cranky ?  Not sure what you mean ?  I think you want one decimal point added ?

Thanks boB

Yeah 1dp would be swell if that doesnt complicate anything.

Hey, the SOC reset looks good. Didnt reset this morning, (todays a skip day). I was also suprised to see no reset on any of the reboots both bully and breaker yesterday morning. Appears to saving to eprom not just at midnite...

[boB]

Excellent ZB !   That's what I wanted to see !

Not sure about extra digits.  We'll see though.

Thanks,
