see Victron Datasheet: Connecting other lithium systems to Multis and Quattros

This data sheet explains how do interface. From the voltage specifications, you should have compatibility, However do make sure that you have sufficient packs to handle the peak current of the inverter. 60A nominal current for a 100Ah pack is a bit light, but similar to pylontech and BYD packs at 0.5C.

to know if its compatable, you would need to ask the battery manufacturer, otherwise if there are interface issue's you will have nowhere to go to get it sorted, the main area of concern would be the bms interface, make sure its compatible.

We are currently testing these batteries with Victron systems. We have found that the battery is recognised as a Pylontech module (quite common with 3rd party BMSs that are similar to Pylon). This is an issue since Pylon batteries are hard-coded in GX firmware to only be charged up 52.4V, to ensure system stability, so the CVL voltage that the CFE calls for (56.1V) is ignored by the Cerbo GX and therefore the battery cannot be charged above the 52.4V hard-coded voltage. I have read of other modules that suffer the same issue. We tried with Type A and Type B cables, and both times, the CFE module was recognised as a Pylontech, resulting in not being able to charge correctly.

My own question in another post yielded a response that in the beta version v3 of VenusOS, this issue is now resolved. We will test our CFE with a beta version of firmware, and report back here for your reference.

Did you succeed in getting that 51.2 V system to work correctly?

The problem was with the BMS announcing as pylontec which are usually 15s batteries but are managing the 16s batteries.

The issue was the GX would not let the 16s battery charge fully since for anoylotec this is it correct.

There was a fix for this in GX V3 00.

It seems that CFE has completed compatiblity with Victron Cerbo GX, here is the document:
