Pylontech US2000B x12

Hi all. I have the following setup:

3 x Axpert MKSII

30 x 330W PV modules

12 x Pylontech batteries split into 3 cabinets of 4 batteries but interconnected ons bus

1 x ICC controller
 

I am currently able to monitor 8 x batteries through the ICC (limitation on viewing and a Pylontech limitiation). The last 4 batteries are not controlled by the ICC (I think) as the syncronisation of lights on the battereis themselves differ between the first 8 and the last 4.

Would it be possible to economically monitor all 12 batteries (looking to expand to 15 later) on an individual level through another program but still using the ICC to make decisions on SOC and perhaps seeing all connected batteries as 1? 
 

Any advise would be greatly appreciated.

Hi Louis,

I believe that the Pylontechs can only have 8x in a group. If you want to have more than 8x then you need to make use of their LV-Hub to monitor and control them, so I think at the moment you are only making use of 8x of them.

So I guess that you should add in the Pylontech LV-HUB and then split them in 2x groups of 6x which should then allow you to make use of all of them.

That I'm not sure of. The way that I understand it is that it should work similar to how it works now with the LV-Hub becoming the master similar to how it's working at the moment as you can connect to the hub using CAN / RS485. I'm just not sure how exactly it will look and if you will see 12x batteries, 2x groups of batteries or just 1x bank.

I think the best would be to ask ICC as I'm sure they would have had installations using the LV-Hub.

I have spoken to Centurion Solar, will be able to see the whole battery bank running through the LV hub as one unit apparently. I will make the LV hub purchase in next month to see how it incorporates and allowing me to fully utilize all 12 batteries and in future add more hopefully effortlessly.

Correct. The LV hub runs the same protocol as the mater battery. Just rememer to set the DIP switches to correctly terminate the CAN-bus. I believe the unit ships unterminated by default, an easy thing to overlook.
