Classic 150 Incorrect Log Date

[crunnells]

Yeah, if I change the status screen to show the line graph, it correctly shows the peak wattage over the past 12 hours (or whatever it is). So that's working!

I've powered the Classic off and back on not that long ago to see if that would reset the charge status to bulk, and it seemed to keep all of the settings correctly (and it DIDN'T reset the status from Float to Bulk). So, maybe it's not the EEprom? I dunno, there seems like there's something not going right in the system and it's not related to the way it's configured... Basically, we're using all of the factory settings EXCEPT that Aux 1 and 2 are used to power a vent fan and the WBJr.

It might be worth RMAing anyway because I don't think there's something I can do from here... Unless you want me to export all of the modbus registers or something, to look for anything weird.

Regarding the ground shock, the Classic actually wasn't grounded at the time (I put off doing it because without a ground rod the whole thing is moot), but it is now. Makes sense that the SPD draws power for the LED (I didn't think of it at the time). I just emailed my brother-in-law and stressed to him that he needs to get it done ASAP because like you said, the SPD isn't doing jack if it's not actually grounded.

We had thunderstorms roll by earlier this week; we just got lucky and didn't have any close strikes.

Just wanted to bump this because I still haven't gotten a resolution on this problem. I've tried all of the things you suggested, and am running into a wall. I saw this thread that has the same issue (http://midniteforum.com/index.php?topic=1898.0) but most of the problems seem to have been resolved by firmware updates. Unfortunately that hasn't fixed my issue...

I also sent an email via the contact form on the Midnite site requesting an RMA, but haven't heard back yet and it's been a couple of days.

Anyone?

have you tried the Vulcan Mind Meld yet? (Factory reset)

zoneblue, TomW, one of the first things I told him to try was a VMM after he updated the firmware. No change to that problem tho. Keep in mind it came like this out of the box when we first set it up too.

boB, it's a Classic 150 with a MNGP from Q2 or Q3 last year or so. Out of the box it had the pre-WBJr firmware. I've never checked the time synch in the tweaks menu, but I'll take a look. I suspect this isn't the problem. The time and date are set correctly in the menu, and they update correctly, but the date doesn't change at all in the History menu. There's no way to select a different date because the screen shows "Invalid date" then shows the invalid date (15/31/2127) so no logs are selectable. I don't recall if we've tried accessing them from the Local app or not.

I can say with certainty that it does NOT reset from Float. We had a span of cloudy days here, where I was running the generator every other day, and their Classic was on Float while their batteries were at ~22v. I had to re-initiate it via the menus, and it hasn't reached Float again (since it hasn't been sunny). We're not using the Skip Bulk settings at all.

Okay back to the OP. You still have not told us what firmware you have on this Classic. Need the Classic and the MNGP versions. Secondly, what log menu are you looking at Daily or Hourly? Or are you looking under the Status Menus? It is not unusual to find garbage in some locations of the log that have never been written to yet. The only way to get around that is to erase the logs or wait until that location gets written to. IIRC there are 388 locations so that would take over a year to write to every locations, which is why I suggested to erase the logs to get a fresh start as erasing them seem to put all zeros in all locations. Then each night at 23:59 a new entry will be logged.

One of the things I mentioned in the first post is that we reset the Classic to factory settings (VMM) and updated to the latest firmware as of the date I posted. I don't have the version numbers in front of me, but I'm 99.9% sure it's the latest REV 1849 from 4/21/14. I will check and confirm in the morning.

Just in case I wasn't clear earlier, we haven't changed any of the default charge settings either. The only settings we changed were to enable the WBJr and set Aux1 to power a vent fan. None of the Bulk, Absorb, or Float voltages or times have changed from factory settings for 24v.

Also, after reading the thread in my earlier post, I double-checked the little battery in the MNGP and didn't find any evidence of anything sticky blocking the contacts. The battery voltage read 2.8-2.9 (out of 3v) so I don't think the MNGP backup battery is the cause here.

Secondly, what log menu are you looking at Daily or Hourly? Or are you looking under the Status Menus?

It's the Logs menu that I was referring to, where it shows the invalid date. If I show daily, last time I checked a month or so ago, it currently only has two "days" of data, which actually encompass 6-8 months worth of data. So, the daily KWH for the first day is something like 180kwh (this, from a 1.6kwh system) and the one for "today" keeps accruing, and will continue to do so until I do another factory restore on the system (or maybe just a complete power down, I forget what resets it at this point).

I haven't tried resetting the log...

Actually, now that I re-read the VMM procedure, I haven't done it... I kept thinking that was the factory restore. Derp.

Okay, first thing tomorrow I'm going to do a VMM and report back. I'm hoping this fixes the problem.

VMM is a factory reset? You have to have powered off the Classic. Then hold down the left and right arrow keys and while holding these keys down turn the power to the Classic back on. If you haven't done this it could be your problem.

Please describe what you think is factory reset.

Also when you chose the Log Menu it displays a choice of Daily and Hourly which one did you choose?

@resthome - I thought VMM was the same as Factory Reset (just a different name for the same thing), but I realized I was mistaken.

We've done the Factory Reset a few times (power on while holding left and right soft keys) but I haven't done the VMM (power on, then install J1 and J4 hardware jumpers inside the Classic). So, I'm going to try that in the morning and see if that fixes it.

They are the same thing! The jumper method are for Classic Lites that do not have a MNGP.

Well, of course they ~should~  be the same thing.  Or real close anyway.

So, on the wrong dates, is the MNGP's clock and date set correctly as well as the TWEAK,
Time Sync turned ON ?  Without the Time Sync turned on, the MNGP will not be able to
tell the Classic what time and date it is.

You can look at the Classic's internal clock and date from the MNGP date menu by
holding down the LEFT-ARROW key and pressing the SOFT-RIGHT  key.
It should match the time and date of the MNGPs time and date.

In practice, they're not. I did the VMM, and when I powered the classic back up it was in 12v mode instead of 24v mode. It never gave me the opportunity to select the operating voltage (as you get with the soft-key reset). So I powered it down and did a soft-key reset, and set it back to 24v. Still having the same issue, however.

I checked the firmware versions:

MNGP: 1821:04/14/2014
Classic: 1849: 04/21/2014

This is the 2nd or 3rd time we've updated the firmware, so that's not a valid fix.

Other questions posed earlier in this thread... I can see hourly logs just fine, either my moving thru the status screens OR by accessing them from the Logs screen in the menu. It keeps track of the current day info perfectly, showing peak power every 10 minutes, BUT when I switch to Daily (in the Logs screen), it shows the date as 15/31/2127 and a time of 31:63, always. This never changes, except to switch to "Invalid Date" then back to said invalid date.

boB: I'll try to check and see what the time is set to, whether it matches, and if Time Sync is set or not. AFAIK it should be set to the default, because it's not something we've ever changed, and again, we received it from the factory (well, Arizona Wind & Sun) with this issue so it's not something we've changed that has caused the problem.

Have you tried looking at the Offline Data in the Local App. Are all the entries showing the bad data? You have to wait until the Export button is not grayed out before scrolling through the data.

I assume the enable logging is checked.

[crunnells]

I have to double-check, but according to my brother in law, all of the offline dates show the invalid date "15/31/2127" instead of the actual data. I need to go over there and check the date that boB asked for, so I'll have more info tomorrow.

So is it just the date field the is incorrect in the Offline data? Do the other fields have the correct data?

Yeah it would help to have answers to boB's questions on Time Sync and the actual Classic time.m

[boB]

You should now be able to turn off the Time Sync in the Classic TWEAKS menu and just set the time and date in the classic
from the Local App panel.

Of course you have to wait a day to find out if the date change worked by downloading the daily data because
the previously stored data will not change... Only the data stored after the time/date was fixed in the Classic.

You could of course fix the data in the CSV file after it is downloaded from the local app.
