Hawkes Bay in Wisconsin

[ClassicCrazy]

Quick look at the lastest MNGP2 firmware update.
The amps output from the Whizbang and the Hawkes Bay are separate now which works well for me since I have two systems feeding through the same shunt.
The SOC calculation seems to be working okay now too.

Has anyone else noticed the SOC not counting down correctly ? I think this may have started after the last firmware update since it used to seem more accurate.
I have the same settings in HB as in the Classic that shares the same shunt .
The Classic is showing 88%
and the Hawkes Bay 97%
MNGP2 firmware is 23.2.1
HB firmware is 23.2.1.2

I think that Mario may have found some of these issues, Larry.

I will ask him tomorrow about this.

Thanks Bob .
latest readings -
Classic 83%
Hawkes Bay 92%
battery bms 84%
7 inches of snow settled down to a fine grain dense 5 inches when it started sleeting.
Last week was like March springtime and all the snow had melted away.
Back to February winter reality in Wisconsin !

Any progress on getting the Canbus info for Hawkes Bay ?
I would be happy to just be able to get bare basics like battery voltage and charging current .
I could then put it on the graphing of what I already do with the Classic which is on the same battery.
Without the battery voltage sense enabled yet it is really difficult to get the two systems to work together.
My other item on the  wish list would be to have MNGP2 screen backlight to be able to adjust all the way to off or close to that.

updating HB from 23.02.01.02 firmware to 23.03.21.00     , update stopped and got Alert  Failed : 015 . Second attempt update completed okay. For anyone who has their MNGP2 remote like I do make sure you check HB after update since it will trip the PV breaker .
After that tried updating MNGP2 from 23.02..01.00  to 23.03.16.00  three times but it never started and got Alert Transfer Timeout.
I power cycled HB , tried beta updatater again but android app didn't see HB .
Restarted android phone and then tried app and it found HB  and MNGP2 update worked fine.
Maybe it would have worked had I restarted android phone previously ?
Next time I will try that if update is hung up for some reason.
I am curious of the MNGP2 about the MNGP2 backlight ?
It goes from 10 to 99 for dimming . Is there a reason firmware update can't make it go down to 0 and dim it all the way ?

Larry,
My findings here, for update that fails, in no particular oder:
1- To close to the MNGP2, If the RSSI gets lower than 65 it seems picky
2- To far from the MNGP2, If the RSSI is much above 85-90 it seems picky
3- Reboot blue tooth on phone, It seems like to me my phone gets clogged up and cycling BT seems to work a lot
4- No other things going on the phone. Dont play a game or check email, keep the display alive. This seems more problematic on Rosie then the MPPTs
5- Reboot the phone
6- Reboot MNGP2

yeah I did have the phone right next to the MNGP2 antenna .

FYI - You can unplug the CANBUS cable to reboot the MIG2 (engineer slang for MNGP2) or pop out the speaker/BT cover and there is a RESET BUTTON lower left corner...

The SOC seems to be working well again after last firmware update.
It is now close to the same as Classic and batteries bms report.

This is great to hear, Larry !   Thank you for checking that.

Lettuce know if things change.

I did the latest MNGP2 beta update.
Released 23.03.30.00

There was also 23.4.6 for the Hawkes Bay update.

I noticed that the Time in Float counter finally cleared the numbers in it so it is zero now.
The Absorb Timer never seemed to count in the past.
It will be a day or two before we get enough sun to charge the batteries again so that I can see what happens with those.
It was in the 80's last week and plants growing and blooming. But winter just came back to Wisconsin with 3 inches of snow ( more predicted) and some nights in the 20's.

Larry,
I too updated to the latest firmware for HB, BAR and MNGP2 today.  I did a reset before the day was finished to install arc fault and ground fault, so I'll see what I get tomorrow and let you know.  I did walk through several menus to find a few new things for us to work with.  It is getting better all the time.

Brain - What did you spot that is new ?
Maybe I never noticed before but I can easily scroll through the data history.
I swept the snow off the pv here and am charging - even though it is still snowing the sky is bright and just above freezing so snow melting on the pv as it lands.
