  1. I thought perhaps 'R' referred to 'recovery' - so 'Over Voltage' for example is 3.7v per cell and the system will clear the error and resume normal operations 'Over VoltageR' when the voltage drops to 3.6v per cell
  2. Dear Plonkster/Youda, I am having a strange problem with my Pylon Tech US2000s - I previously had 16 bricks (2 stacks of 8 bricks) connected to a Victron GX device - I just added 4 new bricks (3rd stack) to make 20 total and now the CCL on the battery parameters page of the Venus GX is limited to 300A - effectively 15A per brick. If I disconnect the 4 new batteries, the CCL goes back to 400A for the 16 old bricks, if I connect the new 4 batteries alone, the CCL is 100A. The expectation is 25A per brick so 500A CCL for 20 bricks. What can I do to get the batteries from limiting the charge current? I have 20kw of panels mounted - any way to force the CCL to a higher value? I have checked and the 16 old bricks have firmware version 65.9.1 whereas the 4 new bricks have firmware version 66xx - is an upgrade required to same firmware? I also eliminated temperature as an issue - batteries read 25 to 30 degrees depending on time of day.
  3. Thank you very much. I navigated to the directory ran > cp dvcc.py dvcc.bak ----- to backup the original file... Then > nano dvcc.py and saw the Pylon quirk and made the change. I must say whoever wrote those scripts has a great sense of humor :):):) I owe you a beer!
  4. Dear Plonkster, I do hope you are staying safe during this world wide COVID 19 outbreak? I have waited so long for the Venus 2.60 update but as of now, Victron are still at v2.54 Please can you point me to the specific script/place to update on the Venus GX where I can change the hardcoded 52v to 52.5v please? I already have root on my Venus GX and have even enabled MQTT and can harvest DBUS values to a RaspBerry Pi (wrote a Python script myself using the Paho MQTT library) which then publishes to emoncms.org I say this to demonstrate that I am fairly confident that I can safely perform the change if only I knew where it is coming from. Appreciate your help.
  5. @Youda A good day to you. I have seen many examples of you using the PylonTech CLI to gain access and run commands. How does one access this CLI? I see nothing in batteryview that may help - I tried to use Putty sofware to connect to the COM port number but all I got was a blank screen. I am able to talk to the BMS with batteryview software, please can you give a step by step guide how to access the CLI too?
  6. @plonkster Many thanks for your excellent support. I could find no setting available to disable external control or networked operation when I connect to the MPPT through VictronConnect. On the GX device it is possible to reset the 'BMS control' feature but it just starts right up again if I connect the MPPT's VE.direct cable back to the GX. I would like to have the MPPT connected to the GX for easy monitoring and reporting but the MPPT should not be controlled by the BMS but rather run independent based on the parameters I configure. Is there any chance I could achieve this?
  7. @plonkster Thank you so much for this info. I can't wait to install that update. In the meantime, I have considered taking one SmartSolar MPPT outside the Venus GX's control and setting the charge parameters to 52.5v and let that MPPT run unmanaged by the GX. This leads me to my next question if you please? I can think of no setting I made on the MPPTs to make them slave to the GX - I simply setup DVCC on the GX and connected the MPPTs after setting them up with conservative user defined settings 52v for float and absorb. Is it sufficient to simply unplug the MPPT's VE.Direct cable from the GX device, reboot the MPPT and the MPPT will start up independent and no longer run by the GX?
  8. @Youda @plonkster I was wondering if it was possible to set my Venus GX to charge my PylonTech batteries at 52.5v My understanding is that Victron put an override in their GX devices to charge at 52v regardless of what voltage the PylonTech BMS is broadcasting over the CAN bus. How can I make Venus GX tell my Victron SmartSolar MPPT and Quattro to charge at 52.5v?
