Wrong CCL in VRM

EasySolar II GX, Cerbo, 4x Pylontech US5000.


CCL set to 200A, was set by Pylontech to 80A. VRM still displays 80A

Hi @kevgermany,

This is expected behaviour.

The advanced widget you're looking at in VRM sources its data from the battery BMS. Additional limits set elsewhere (like a custom DVCC setting) won't affect the data shown there.

In this case as well, because the limit set by the battery is less than the 200A you have set manually, the system will not override the battery BMS.

To add, DVCC is not an override. The system honours the lowest of any two limits.

Is there a way to show ESS CCL value on dashboard or dash/advanced in VRM.

There are values from shunts but not what I'm looking for...

You can see CCL in a custom widget in the advanced section

I can find CCL vale for Lynx Shunt, but there is no data to display. No other devices have CCL value and I'm looking for one from ESS.

Thanks. New to this side of things. I saw the limit changed during the day. So the batteries appear to be setting a current limit depending on SOC maybe more.

Cleverer than I thought.

Exactly right, it tails off above 90% SOC, at least that’s from my experience.
