I'm installing my first Rossie system with 2 of them stacked and 2 Powerflo16 batteries. There doesn't seem to be anything in the Rosie manual about how to set the system up for use with these batteries. I assume I just connect all the CANBus ports in line.
I'm not using a Whiz Bang Jr.
Will the batteries automatically communicate their SOC to the system? Particularly, I want to start and stop a generator based on the battery SOC. The menu items mentioned in the manual are only starting and stopping on voltage.
It appears there have been a lot of firmware updates flying around. I installed the MidNite Pro app on my phone but the site I'm going too (like almost all of my off grid sites) has no cell service. From reading the manual on firmware updates it makes it sound as if the phone needs service while connected with Bluetooth to the system. Is this the case? I hope not or it will be nearly impossible to update anything.
Let me try and answer these in order.
1- Powerflo16 integration, Rosies each have 2 canbus jacks and MNGP2's each have 2 canbus jacks and the PF16 has 1 canbus jack. The order you string the canbus in doesn't matter for example Terminate 1 Rosie then go Rosie--Rosie--MNGP2--PF16 or terminate the MNGP2 and go MNGP2--Rosie--Rosie--PF16 just remember these key items
a- Use the included 2 wire can cable that comes with the PF16 to go between the PF16 and the Rosies
b- Plug into the master battery canbus, the master is the one with an empty Link IN port
c- Use the included cable to go between the PF16 Masters Link OUT and the PF16 Slave Link IN port
d- Turn on the batteries by pressing the master power on button only
2- SOC, Yes the PF16 will automatically send SOC, Battery Voltage, Battery current and more when closed loop so SOC used for AGS will be from the BMS
3- Firmware updates, Midnite Pro is for the AIO inverter not the Rosie system you want to get the Midnite Standard updater here: https://www.midnitesolar.com/firmware.php?firmwareProduct_ID=8 it will allow you to download firmware when you have internet and then do updates on site with no internet.
Some helpful info, here is a video I did on updating and the update app https://youtu.be/fj16PzBqEjI
I have also attached two items, A stacking instruction guide for Rosies and an MNGP2 Power Point that I find helpful
I really appreciate the help. I got it wired up today and working even with the old firmware. When I tried to get the MNBLE Updater on my phone I got this message: This app isn't available for your device because it was made for an older version of Android. My phone is probably at least 3 or 4 years old so that was kind of surprising. I'm not sure where to go from here to get the updater working.
The MNGP2 didn't give me any choices for AGS on SOC, I'm assuming that's due to the old firmware.
Also, I never saw SOC displayed anywhere on the MNGP2, hopefully the new firmware will fix that as well.
I have a Classic 200 hooked up to charge the batteries. I couldn't seem to find the proper settings for Absorb, Float, etc. in the Powerflo16 manual. Does anybody know where I could find that? I programmed it to a nice safe 55.2 Absorb and 53.6 Float for now.
Also, the cable that came with the batteries that is labeled "battery" on one end and "inverter" on the other end looks just like a standard Ethernet cable. It seems to have all 8 wires in both ends. Not 2 wires as you mentioned. Did I get the wrong cable with the batteries?
I too, just installed (2) pf16 batteries paired with a rosie and hawkes bay. The cat5 wires included that are labeled "batteries/inverter" indeed have 8 conductors on both ends. I just tested them with a cable tester and no special pin out is utilized. Did the wrong cables get sent out? If so can anybody provide the pin out that they are supposed to have?
I've run the batteries a week with the 8 wire cable and could not tell if my rosie/hawkes/pflo16 were truly in closed loop. Is there a way to determine through the mngp2 that a closed loop status has been achieved?
After a full day or 2 of charging the SOC populated and claimed 100% as did the whizbangjr SOC. I've just come into a few straight days of clouds and no pv input and the SOC on the mngp2 is still showing 100% which cannot be true. The master battery SOC light indicator is showing 67-83%
When attempting to update with MNBLE Updater ap on my phone, I've also run into the message that the app isn't available for my device because it was made for an older version of Android, and my phone is several years old.
I appreciate any help.
I had to use an older phone I had lying around to get the app to work. After that I updated everything. Only then did the SOC communicate to the Rosie.

If your firmware in the MNGP2 is new enough you should see State of charge when plugged in, Another way to tell is press STATUS and turn the knob to see the BMS screens
"a- Use the included 2 wire can cable that comes with the PF16 to go between the PF16 and the Rosies"
Not all Powerflo batteries come with two-wire CAN cables, Some come with standard ethernet cables.
I think the PF16 comes with an 8 conductor and it is OK but the PF5 can not use an 8 conductor
Is anybody with the Rosie and pf16's having issues showing the correct soc?
I used all suggested settings from the MN website for the pf16s. The soc tops out at 95% consistently. I use solar assist so it is easy to monitor this. The battery volts are topping out at 56.2v which seems like 100%. Any thoughts?

If your MNGP2 is old enough code to not have SOC for AGS than it will also not have closed loop support it needs to be updated.
As for the cable I believe the wires are not connected in the cable as it does work

The Powerflo battery drastically reduces charge current above 90% to obtain long cell life, The Rosie system will throttle back and drop out of charging around 95-100% this is intended behavior to maximize cell life

I believe I am mistaken and the PF16 doesn't ground out the Rosies RS485 and is OK with an 8 wire its the PF5 that grounds out the Rosies RS485
