Victron ESS battery compatibility Pylontech US5000(B)

Hello, I've found some threads regarding compatibility of the Pylontech US5000 battery (not the UP) with the Victron ESS system but a lot of them seem to be mixing up the UP and the US version.

The exact battery type (US5000 or US5000B, see https://en.pylontech.com.cn/pro_detail.aspx?id=134&cid=23 ) is currently not listed on the battery compatibility list of Victron (https://www.victronenergy.com/live/battery_compatibility:pylontech_phantom)


At this point, I'm assuming it's compatible, but I'd prefer a formal confirmation of this.

Even better: would it be possible to update the documentation page with compatible battery types? During certification of the electrical system by a notified body, some inspectors are pretty specific about the compatibility, certified by the vendor of the ESS, between a BMS and the ESS system.

At this point, I don't have the documentation (or certificates) ready to back this up.

Hi @axl1988

Pylontech report to us the same BMS mappings for the US5000 & US5000B as the UP5000.

I have updated the Victron Pylontech Battery compatibility guide to include them.

I am still waiting for some US5000 modules to arrive to test this.
The only documentation in the US5000 manual states that it is compatible with the other 48V modules in the family and describes the order in which to connect a US5000 with others.

The Pylontech site is a bit poor, so finding the manual there is not easy.
I had Google to off and fine one for me, page 6 here: https://portal.segensolar.de/reseller/docs/PM0MUS500255-US5000%20US5000-B-SD21US501001-Installation%20manual.pdf

It is working for me flawlessly with 2x Pylontec US-5000 and an Easysolar II GX (connected via CAN bus)
