Hello and congratulations again for your great video I had a question: can the JK-PB2A16S20P communicate easily with a victron multiplus II 5000VA? what equipment do you need special cable in addition? I'm trying to find out about the bms because as I have a large 24 volt 1300AH battery pack I would like it to work perfectly before investing in the BMS and the victron multiplus II! laurent
Nice, I think currently its best BMS version for DIY, I wait for my first 16x cells to setup a bank. My inwerter is a SoyoSource GTN-1200LIM48 means have a CT clamp as limiter who do hybrid OnOffGrid, export only for auto-consumption, zero export to grid, max 900W output. For me perfect !
Hi, can you help explain the hardware you are using to make this happen? I have a jk bms with rs485 port, and I’m wondering if I need an adapter or something?
I have one of the two JK BMSs attached to one bank. I will attach the other side of the bank with its JK BMS this weekend. I want to connect it all to a Xantrex 4548 with the SCP control panel. It uses Xanbus. Think you could help me get it all communicating?
Probably not. I know nothing about Xantrex stuff excpt for the inverter I replaced and have since used to run my shed. It's a "dumb inverter" so just has battery in and 120 out for connections
I had the same issue with mine regarding the mis labeled ports in the manual. So frustrating! I set my BMS to the Pylontech protocol and I'm curious if the GoodWe is the better setting. As is sits now everything works fine except the Inverter doesn't display the detected Ah rating of the battery only the SOC. Does your inverter/dashboard show a battery capacity with it set to GoodWe protocol? Also, does it follow the absorb/float settings you have set on the JK BMS. Mine skips over the absorb phase and goes straight to float.
LiFePo4 batteries don't need to absorb. If the communication is working the BMS will tell the inverter what it wants for voltage and current. I didn't use the plyontec setting long enough to see what worked and what didn't. I have the RCV set to 3.5 and don't recall seeing a float setting. It may have been there. I only changed a few settings and didn't go through them all.
it works great for me. anything i use that surges is a 240v load 6000w is plenty. and there split phase 120v too 3000w on each leg. not to mention that are stackable if you need more. they have a ats, 12kw of solar charger mppt, breakers, ac grid charger too. name another 1400 dollar solution thats better?

You have to have the JK Inverter BMS. It is different than the standard jk with rs485. rs485 only sends data to the screen.
Did you get both jk inverter BMS running in parallel with the 6000xp recognizing them?
right im curious too.
Any update
Yes. Followed the guide from @OffGridGarageAustralia (thanks Andy). Super simple and worked first try.

Does that hub work with old black jk bms (2 blue wire )
Nope.

Many have the same problem where absorption to balance doesn’t work. Interested to see if it does on GoodWe setting.

Why on Earth would you buy a Chinese made 6000 XP, with its low surge capacity in the first place?
