How to configure Pylontech US5000 with Easysolar 2 ? (SOLVED)

Hi all,


I'am new with victron systems, and I tried to find answers in manuals but I was unsuccessful. I need for my company to test a EasySolar II + US-5000 system for autonomous installation. PV + Inverter + Battery work but battery BMS isn't recognized ? I can't get SoC from Victron VRM ? Any other tips than https://www.victronenergy.com/live/battery_compatibility:pylontech_phantom


Thanks,

Aloha, Greg.

You need to use the Victron type A cable between the US5000 and the EasySolar, not the Pylontech cable. If you have multiple batteries, the Pylontech cables will work for battery to battery communication.

Thank you Kevgermany, In fact I tried each cables, the blue and the grey from victron, from CAN.BUS(ES II GX) to CAN (US5000) and nothing changed ?? I added the CAN resistance on ES II GX.


I'm a bit suprised it works to power a vaccum in AC, the battery is charging but in reality the BMS isn't connected, Is it safe ?

On the is it safe question...

Firstly you should set the charge parameters in all/any chargers as a safety measure, even though the Pylontechs will override them.

If you try to overcharge, the built in BMS in your batteries will prevent damage.

So yes, safe.

We had some issues with the bus that were solved by using the terminator on the last battery. It is issued free as acsessoire wit the EasysolarII GXterminator-1.jpg
