Rather than force the settings, which will affect a very large number of users, I updated the documentation.

Ok but lets keep the issue open still; we need to fix this somehow someday.

And which documentation did you update? Don’t forget to check the gx manual.

Some statistics that may be helpful.

Total of 8115 Pylontech batteries on VRM.

Total installations DVCC on DVCC off %
All installations 7083 1032 12%
Venus OS >= 2.50 6882 940 12%
Venus OS >= 2.60 6168 825 12%

Roughly 12% of Pylontech installations don't use DVCC.

very helpful! lets force it on. and then make sure to do it at the start of a beta series that takes a while. Ie the complete opposite of what would happen if we'd make that change now in the latest v2.70 release candidate.

dbus-systemcalc-py v2.68 & v2.69 & v2.70 & v2.71 & v2.72 & v2.73 & v2…
3140584 
….74 & v2.75

Add full DVCC support for Inverter RS, including CVL, CCL, SVS, STS and SCS.
Closes victronenergy/venus#803
Implement logic for ActiveAcIn in systemcalc so it can move out of the GUI
    Fix problem where grid meter reading disappears from GUI when Multi is off
Fix hubtype indication
    Turning off a Multi in an ESS system would cause hubtype to change to Hub-1
    Overview would change and Critical Loads block would disappear when turning off Multi.
    victronenergy/venus#806
Improve System State display
    In system without a Multi but w* dbus-generator v1.4.0 & v1.4.1
Update to python3
Fix unit tests broken since Venus 2.70.ith a managed battery, show when discharge is
    allowed/disallowed by battery
Support for Lynx Smart BMS (Backported to 2.72~2 as patch)
    Stop all chargers when CCL=0 (charge current limit) is received.
Switch off inverters when DCL=0 (discharge current limit) is received from a managed battery
    For Inverter RS, copy the the DCL to the inverter. Firmware 1.04 switches off inverter.
    For other inverters (not Multis), switch the inverter off by setting Mode to Off.
    victronenergy/venus#736
Fix possible crash when non-ascii character used in battery measurement name
    No actual cases found, part of a wider unicode cleanup
Clean up BMS selection where there is another battery monitor in the system
    Since Venus 2.30, it is possible to set the battery monitor to a BMV, but still use the
    charge parameters from a BMS in the system.
    This hidden functionality is not shown anywhere, so instead remove it and make it simpler.
    victronenergy/venus#783
Force DVCC settings for pylontech batteries
    Set this as the documentation already advises: DVCC=on, SVS=off, STS=off.
