charge current Multiplus 2

hello victron guy´s,


I have a multiplus 2 gx and the charging current bever exceeds 31A. The datasheet says 35A.

The multi is connect to a grid in Germany.

Batterie is LiPo. with 2 channel BMS

MinV=45V

MaxV=60,75

Capacity= 100ah

Why doesn´t the current go to 35A? What can I do ?

@Dominic Ewen

If the BMS in the battery is connected by a data cable it could be dictating to the color control what the charge current should be and limiting it.

There is no data connection to the bms. Only two channels digital. Charge and discharge allowed. The bms is an own development. Thanks for your support.

Did you ever solve this problem?

My Multigrid 24/3000/70 is charging at 60A max although it's configured at 70A.

I already tried disabling "weak AC" and increased AC in current limit wich don't change anything.

Hi all,


this is normal, the 35 amp is the maximum charge current at 48 volt, higher voltage means lower charge current (charge power remains about the same)

that makes sense, in my case then still it's quite a bit lower than 1680W...

60A @ 26V is only 1560W.


I'll consider it as tolerances.. thanks for the explanation!
