3. Operation
3.1 Protocol
CAN: CAN-Bus-protocol-PYLON-low-voltage-V1.2-20180408 or above.
RS485: RS485-protocol-pylon-low-voltage-V3.1-20180408 or above.
3.2 Cables Connection for US2000/US3000 under RS485 or CANBUS.
3.2.1 Cables Connection for RS485
⚫Each battery group can configure maximum 8pcs US2000B Plus or 8pcs US3000.
⚫LV-Hub-A configures maximum 5 group batteries.
⚫RS485 communication needn’t additional cable and power just a simple hub is enough.
7/ 14
18BISV0501
⚫When each battery group’s current is >120A, this battery group must configure 2 pair
external power cables like the diagram.
⚫The details of ADD Switch setting also can see the menu of battery.
3.2.2 Cables Connection for CAN (single HUB)
⚫Each battery group can configure maximum 8pcs US2000B Plus or 8pcs US3000.
⚫LV-Hub-A configures maximum 5 group batteries.
⚫When each battery group’s current is >120A, this battery group must configure 2 pair
external power cables like the diagram.
⚫The details of ADD Switch setting also can see the menu of battery.
⚫When using with SMA SUNNY ISLAND, the ADD on HUB(or master HUB if there are multiple
HUBs) must be 000011(for B14V0105 presenting on product label) or 000101 (for B14V0106
presenting on product label).
3.3 Cables Connection for US2000C/US3000C/UP5000 under CANBUS
Connect power cable first:
1) each pair of cable hold max 100A constant current. Connect enough pairs of cable based on
calculation of system current.
2) Suitable protection breaker between battery system and inverter is required.
8/ 14

3) connect power cable of LV-HUB
4) Make sure all dipswitch is X0XX, then turn ON batteries.
5) After all batteries running and buzzer of master battery in group1 rings 3 times. Means all groups are
online.
6) Change the dip switch of master battery in group1 to X1XX. Then connect communication cable
between LV-HUB and master battery in group 1.
7) Then turn ON LV-HUB.
Detailed information please refer to manual of LV-HUB.
