Unexpected Pytes battery charging limit

[nicewind]

Hello Community,

actually dealing with an issue of my multiplus II connected with 2 parallel pytes batteries.

Charging current is limited at one point. As shown in the picture, the setvalue of charging power increases and the actual value cannot follow anymore (red markings). Below this point, actual value is more or less following exactly the setvalue.

Charging current is not limited in the setup. Battery temperature is 20°C. Any ideas, what can be the problem?

As far as I know, Pytes can handle up to 50A each battery….so no idea, what is going on.

Thanks in advance.

I dont see the issue, what does the graph show us (which value is the blue line, where does it have its source)? Since its kW it cant be CCL which would be in amps. What was the SOC during that time?

Is this a new install, or whats the reason for the limited battery charge voltage in DVCC? And whats the reason for enabling SCS, AFAIK that does not need to be onwith Pytes. Is there a difference if you switch both off?

Also, what kind/model of inverter are you using?

with 2 parallel pytes batteries.

Which batteries exactly?

Why you have manually set the CVL parameter?

The Pytes BMS supports Victron COMPLETLY.

Can you post these values?

I use two of them:

Pytes E-BOX-48100R-C

Why you have set MANUALLY the CVL?

Let do the work the Pytes BMS!

It works.

If you manually limit the CVL the charge current can goes to ZERO if the battery voltage reaches your CVL Limit.

Pytes defines the MP voltage settings for his battery models. Do you have set this?

But this limits will not be used if the BMS do his work.

Your firmware of the Pytes batteries is up to date?

Pytes E-BOX-48100R-C

Thanks for support.

I was just following instructions from my dealer where I got the hardware from.

So I removed the CVL limit and actually looking for a console cable.
