I am guessing you have 8 US3000C per bank?

Okay so each banks master needs to have the following ADD Switch settings

Bank 1 Master: 0100

Bank 2 Master: 0010

Bank 3 Master: 0110

Bank 4 Master: 0001

Bank 5 Master: 0101

Baud rate of 115200

the ADD dip switches for every other battery (All of the slaves) should be down.

On the LV HUB connect the COM Port to the CAN IN port.

Connect the power supply to the LV Hub

Connect each battery group one by one and turn them on one by one checking for errors.

This is a Victron community not Pylontech.

But here is a Pylontech support guy in the community, maybe he can help.

X means 0, Before you turn on the battery modules. You need to make sure all the dip switch is on 0 position and connect the communication cables between master battery of each group. (The cable between Lv-HUB and #1 Master battery connected later)

After all batteries running and buzzer of master battery in group1 rings 3 times. Means all groups are online.
Then Only change the dip switch of master battery in group1 to 0 1 00 .
Connect communication cable between LV-HUB and master battery in group 1.
Turn ON LV-HUB. Detailed information please refer to manual of LV-HUB.

Hello Victron community!

This is my first post here, as I'm finishing my first Victron+Pylontech installtion at my home. The setup is 3 Victron Multiplus II + 12 Pylontech US3000C + LV-HUB. I tried everything, read all suggestions in this forum, tried hundreds of combinations, but still got the same effect - LV-HUB doesn't communicate with US3000C batteries. After LV-HUB switching on (and performing all the required connections and batteries configurations before of course) I can hear one beep and later status led is flashing in red, no other signs... No matter of combination, order of steps, cables types etc, the effect is always the same. I'm clueless.

When creating just one group of 12 batteries and connecting it directly with Color GX, bypassing LV-HUB, it works fine, but trying to use LV-HUB give me only frustration.

I've read that some folks did LV-HUB firmware upgrade, but I cannot find tools/firmware files for that. Any help would be much appreciated!

Best regards,

Rafal Grzech

why do you want to use the Hub at all?

For 12x 3000c it’s not required.

heya, for 12 US3000C you don't need the LV-Hub? Do you have by any chance a schema or a picture with 12 batteries connected?
