Closed loop with Rosie/ Barcelona /hawksbay

[mahendra]

So I am just gonna say this straight .

When would the Rosie /Barcelona /Hawkes bay gonna talk to Midnite batteries right out of the box?

We are finalizing the testing as we speak and hope to release the code maybe next week, It is working great FYI

Thanks FNG .

Would this require any additional hardware like the MN commbox?

While I am at it MN can you please sell me Four power Flo BMS .
I need to replace the jk's I have.

If I understand it correctly - the Midnite batteries will communicate with Pylontech protocol . Your JKBMS should also be able to communicate with that protocol depending on exact bms model.
So you may not need to replace them -  maybe just program the output of them.

Midnite killed the MN Commbox project in August.  At that time, they said they were porting the code over to Solar Assistant so you could monitor and/or control Rosie/Hawkes Bay/Barc from that program.  As of this morning, Solar Assistant still does NOT list Midnite Inverters/Batteries as supported equipment.

Thanks .

I saw the update for firmware and closed loop communication for pylon.

So can I please purchase 4 power Flo bms.
I know I can swap out with others but prefer to use one that is as close as possible.

I even have the original glitchy first generation EG4 life power bms ,don't wanna use those too much headaches.

It's a bummer I already have batteries.

Looks like we may have finished up the monitoring portion yesterday, I will be going over the solar assistant today closely. Anyone interested can get the SA and the USB to CAN cable and we can get you updated into the beta software

Nothing needed, the 2 wire can bus cable comes with the battery and it simply plugs into the Midnite can bus. The only time an extra step is needed is with stacked Rosies as Rosie uses the can bus cable for 2 more wires for RS485 to control stacking so the battery has to plug into one of the Rosies and you must install the RS485 termination jumper on that particular Rosie

Ryan - can you explain this a bit more for those of us with other batteries that speak pylontech.
We just connect our battery Can port to the Canport on the Hawksbay in my case ?
There are two Can Jacks on the Hawkes Bay . One of them goes to the MNGP , the other will go to the battery. So we only need the two Can wires from battery Can jack to Hawkes Bay  ( canbus jack pin 4  Can Hi  pin 5 Can Low ) ?
Where would the Solar Assistant usb to Can cable connect to ? I guess there is an extra can jack on the back of the MNGP2  - is that the place ?
Do you have a link to a USB to Canbus cable that would work ?
thanks

Yes, we need to know if a standard network cable or specific cables need to be wired for this.

Additionally, would this only apply to batteries that support pylon, or would the firmware be able to help with other protocols?

I am eager to test.

You may need to make a custom cable for your batteries depending on which pins  are used by your bms for the canbus jack. It wouldn't be hard to make one though once you know the pinout of your bms jack and the pinout of the Midnite controller or inverter.

Here is the pinout for the Midnite battery ( from the manual) and the pinout of the Hawkes Bay, Barcelona , Rosie jacks
Also showing pinout from my Pace BMS batteries. So for my batteries the Canbus wires match up so a regular Cat 5 cable should work. But since the Midnite documents say to leave the other wires floating ( disconnected ) and I am not 100% sure there are no other connections on the other pins on my Pace BMS Canbus jack - I will clip all the other wires than the two Canbus on on 4 and 5 ,and fro the ground then I will have to connect pin 8 from Midnite controller to pin 7 of the Pace BMS  .

So all devices (Except the battery) have 2 ports so Solar Assistant on one end and battery on the other, So for example:
Solar Assistant to MNGP2
MNGP2 to Hbay
Hbay to Battery

With our powerflo the cable is included. with others you will need to look at the pin out and make sure Can HI goes to Can HI and Can Low goes to Can Low for example.

Yes as we put +9v and GND on that canbus to power the MNGP2 bad things could happen if you run all 8 wires
