CCL to low? #51

Closed endurance1968 closed 2 months ago

Hi,

issues and a problem to understand how CCL calculation works. From the logs I get

If I then check the Venus system CCL is set to 100 only (should be 150A)

any idea what to check?

Config json:

{
        "excludedServices": ["com.victronenergy.battery.socketcan_can0_vi0_uc288664"],
        "logLevel": "DEBUG"
}

installed version is 3.0.61

If you are using DVCC, then the CCL will be capped by that (under DVCC menu, you can set a max current limit, in dbus, "com.victronenergy.settings", "/Settings/SystemSetup/MaxChargeCurrent").

OK got it - tested and confirmed. :)
