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...

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.

@kevgermany Hey Kev!
I have an identical setup (Easysolar 2 GX 5kVA & 4 x US5000 pylontech).

Did you ever manage to get your batteries to charge faster?

Mine still charge quite slowly even though there is no overheating and no alarms or warnings.

It just keep dumped most of the power into the grid instead of the batteries and the maximum state of charge has also dropped to 88% for no reason.

My installation is less than half a year old and it used to work just fine charging to 95% at much higher amperages.

Now it's just slow and doesn't fully charge anymore.

Did you ever get the console view via batteryview to work?

Mine are charging fine. But the use at the moment is very light.

Never tried battery view.
