More Communication, More Power | The Pylontech Low-Voltage Combiner Hub

A Pylontech Low Voltage Hub (LV-HUB) allows you to combine more than the default 16 Pylontech batteries for up to 96 batteries in a communicating 460.8 kWh power bank. In this video, we show how to set up the Low-Voltage Hub and discuss its advantages, particularly when paired with Victron Energy equipment. This battery combiner hub is compatible with the US3000C and US5000 battery from Pylontech.

Mike, thanks for another excellent video! Given your experience with both Victron and Pylontech, could you create a video explaining how to effectively set up one or more Pylontech US5000 batteries with a Multiplus-II controlled by a Cerbo GX? Please cover how the Pylontech BMS functions and provide detailed instructions on configuring the ESS Assistant with the mentioned equipment.

I have 12 unit of us 3000 ,any explanation on the dip switch settings

[@intelligentcontrols]

Hello, unless you are planning on adding 5 or more units to your system, there is no real need to mess with an LV-HUB for 12 US3000s. For normal configurations, the short answer is that the DIPs never need to be changed from their default positions. If you happen to be connecting to an inverter via RS485 using a 9600 baud rate, then DIP1 on the master battery (they are labeled upside down) needs to be turned on.

very good

[@intelligentcontrols]

It's pretty cool, right? The more we learn, the more we are impressed with Pylontech.

hi, i have 2 us 3000 batts on my system and i have access to two us 2000, can i mix these together?
regards

[@intelligentcontrols]

Hey, thanks for the question. You can mix the US3000 and US2000 batteries. When combining them, just make sure that one of the US3000s is acting as the master battery.

Hi Mike first time watching your videos, very interesting. I wonder if you could help me. I have 7 pylontech extra 2000 batteries that hadn't been used for a fee years. Have managed to get some charge into them by changing settings on my Solis inverter to lead acid. Unfortunately am getting can comm fail . Am guessing maybe firmware needs updating on my batteries but pylontech won't send as out of warranty.. do you think that a hub would communicate with my inverter and my older batteries !!

[@intelligentcontrols]

Hello Mark. Shoot me an email at [e-mail] and we can do some troubleshooting. I can also get you the programs and firmware you will need and walk you through updating the BMS.

[@pieterhill]

Mike, are you sure about dip 3 down on the Master Battery? The manual says dip 2 down... I've tried both and neither seems to have and effect...

[@intelligentcontrols]

Hey Pieter, the dips are confusing because we are used to reading them from left to right but the Chinese have them labeled from right to left. The commissioning process is very order sensitive, if you aren't getting the address beep the first thing to check in the troubleshooting process is the order that you are doing things in. If that ends up not working, your battery might need a firmware update.
See 'Related Resources' here for a good version of the LV-Hub manual, along with my quickstart guide for CAN bus installations.
If you're still having issues, shoot me an email ([e-mail]) and we can set up a call to troubleshoot.

Any explanation on CAN-RS485 port connection? How is that possible?

[@intelligentcontrols]

Hey Jimmy, there is both a CAN port and an RS485 port. The BMS is configured to be capable of communicating via either of these protocols. The CAN protocol is the most straightforward and is the recommended method for compatible inverters. The RS485 can require some DIP settings but works as well and provides a wide range of compatibility.

[@MDAutoteile]

Hallo what is the power connection of the Lv Hub?

[@intelligentcontrols]

@MDAutoteile, the power connection is 48v DC. The combiner hub comes with a power cable that has two little eyelets on one end to connect to your DC lugs.
