Try as I might, I can't seem to get Rosie to display the SOC of my lead acid batteries. My classic 150 and Whizbang jr works fine, but can't seem to get SOC to display on Rosie.

You have to turn ON the WBjr and if the purple wire is connected to Rosie youhave to charge with AC to FLOAT.
Also ALL battery negatives must go through Rosies Shunt.

Okay, Turned on the whizbang and the ac charger until the charger reported float. The status now says SOC CAL and doesn't change.
The negative of the battery goes through Rosie and the whizbang shunt.

Is the Rosie in Absorb ? Did it go to Float ?

Purple wire from the WBjr not connected or not to the correct terminal. Defective WBjr or EXTERNAL SENSOR setting is set to something other than BATTERY like 3rd party or DC out.

Yes, turned on the internal charger went to absorb then float

I'll check the connections internal of the Rosie. Since I had the epanel come with the inverter, I'm assuming it was wired correctly from the factory. External sensor is set for battery.

My Rosie reads SOC

What Firmware versions ? FYI - Sometimes assembly line workers miss stuff...

MNPG 24.1.24
rosie 24.2.13.1
the whizbang is connected and the purple wire goes to the correct connection inside rosie. I reset the wire in the spring connector and it passed the tug test.
mike
Here's some photos of the whizbang Jr inside Rosie. The purple wire goes to the correct location. I do wonder why the last photo says the purple wire should be connected to the classic.
My classic already has a whizbang jr connected to it.
still no SOC on the MNGP

Well, that only leaves bad firmware or bad WBjr hardware. Check with the Android BETA APP to see if there is a newer ROSIE FW, if so update, do a SET SYSTEM TO DEFAULTS under SYSTEM FUNCTIONS (user menu). If still no SOC then EMAIL support@midnitesolar.com and ask for a RMA, send your phone#, address, Rosie SER# and we will get you a new WBjr sent out. Looks like it is a B*TCH to get that swapped, I can see spacers dropping into neverland... Might have to shut down, remove battery positive cable and remove the 300A breaker to get access...I've not tried to swap one yet...

Yeah, when I was taking the the photographs I kinda grumbled about what a job that would be to get the WBjr out of the inverter. FYI... the WBjr was blinking its LED, and while not a operational test, at least the WBjr is alive.
What is on the purple wire? Is it a voltage or PWM signal? I could throw a scope probe on it and see what's going on.
mike
The device (Rosie, Hawkes Bay, Barcelona, Classic) puts a 12V charge on the purple wire to charge a capacitor on the WBjr, then drops it and the WBjr uses the charge to power the MPU and transmits a data stream back up the wire. You could pull the wire out of the snap-loc a little and check for the data stream returning. If it is then either buggy FW or defective Rosie CPU board or bad/loose ribbon cable.
Remember that the PCB end where the purple wire comes out of the WB Jr. points in the direction of the battery negative. Amperes reading polarity would be backwards otherwise.
Negative amp means we are pulling amp-hours out of the battery.

Yes on both accounts

Since CANBUS SOC% is controlled by the MNGP2 be sure the firmware is on the latest. Update BOTH the ROSIE and MNGP2's firmware, they are a matched set.
Like I said the issue can be:
#1 Bad WBjr (we send a new one)
#2 Bad Firmware (you update and reset system to defaults, turn back on Wbjr)
#3 Bad Rosie Control circuit board (You send Rosie back to factory for repairs)
Start with #2, 2022 and 2023 versions had SOC bugs.
Once that is checked okay email for an RMA for a new WBjr. support@midnitesolar.com
That leave #3, last option.
A known bug you can test, start a charge, go to USER/SYSTEM FUNCTIONS and press "FORCE BULK", then hit BACK, go back into SYSTEM FUNCTIONS and press "FORCE FLOAT". There is still a SOC bug in present FW that sets SOC = 100% when you do this. note: unless YOU KNOW your battery is 100% don't trust the SOC% if it happens to set itself to 100%. I still suspect it's a Firmware Issue.

My wife and I survived the total eclipse yesterday, and haven't changed into Zombies, (I saw the movie and it didn't go well for us humans ;D ) so I'll try and upload the newest firmware to both the MNGP and Rosie. The last firmware posted for Rosie was for cold start issues, and I haven't done that upgrade yet. No need as the environment the inverter is installed never gets that cold.
That being said, I have never been able to see the SOC % on Rosie since installed. I use the SOC% shown on the Classic.
Mike
Hooked up a portable scope I have, and this is what's on the purple wire. I didn't take a voltage measurement on the wire. I figure if I see the canbus, then it's got power.
mike
QRPer, looks kind of like Whizbang data
Is that from Rosie or the Classic ?

From Rosie.... the purple wire from the WBjr mounted on the neg battery lead inside the factory wired Rosie ePanel
I guess the next question is, does the remote (MNGP2) show any current being through the WB Jr. ?
The baud rate on that purple wire should be, as I remember, 1200 baud.
Could you capture another screen of that data so I can see if there is a command from Rosie as well as return data from the WB Jr. ?
boB
Re-Installed the firmware for Rosie, the MNGP was up to date.
Rechecked all the connections.
Charged the battery via Roise's on board charger.
And I have battery SOC% now displayed on the MNGP! There is now an extra screen under status that shows WBjr info.
Now the problem is, for me, the charging current from the solar and Classic negative lead does not go through the negative lead in Rosie.
There are two WBjrs, one that is connected to the Classic and the one internal to Rosie. Don't want to disable/disconnect the one for the Classic, so will do some head scratching to figure out how to get both WBjrs to measure the same current going in and out of the battery's neg lead.
that being said, I'm 100% tickled I got the SOC% running on Rosie
mike
Fantastic ! It is a good day then !
Eventually, (sooner than later ?) with the Combox, the MNGP2 should be able to see both shunts.
Hopefully it will aggregate the two and let you see things the way you want to see them.
Wizbandit is doing all that by some kind of software magic.

That would be great, boB. A work in progress I do believe. It would be nice to have the SOC % read the same on both displays, the Classic and Rosie, but I've made progress as I haven't been able to get the SOC % on Rosie in over a year. I didn't want to try and remove the shunt out of Rosie, that would have been a chore.
