Victron & Pylontech US2000B and Phantom-S

The combination of Victron products with Pylontech lithium batteries has been tested and certiﬁed by the Victron and Pylontech R&D departments.

General information about the battery is found in Pylontech's documentation.

This manual is intended to be used in conjunction with the product manual supplied by Pylontech. It provides additional and speciﬁc information regarding integration with Victron systems.

The Pylontech includes a Battery Management System (BMS) with each battery module. This interfaces with the Victron Venus-device and can support multiple battery modules connected in parallel.

1. Product & system compatibility

Battery US2000B US2000B Plus US3000 Plus

Module capacity 2.4 kWh 2.4 kWh 3.5 kWh

1.1 Oﬀgrid, Backup and Energy Storage Systems are possible

Victron + Pylontech can be used for the following system types:

Oﬀ-grid Grid Backup Energy Storage Systems - Self Consumption (ESS - Start page)

1.2 A Venus-device is required, eg Color Control GX (CCGX) or Venus GX (VGX)

It is essential to use the CAN-bus connection of the Venus-device (eg CCGX or VGX) with the batteries for the keep-alive signal, communication of charge and discharge limits, error codes and state of charge.

The minimum required ﬁrmware version for the Color Control GX is v2.15. It is highly recommended to use the latest ﬁrmware version on all connected devices, including CCGX/VGX, Inverter/Charger and

MPPTs. There are regular updates to improve performance and reliability.

1.3 All 48V Multi, MultiPlus, MultiGrid and Quattro are compatible

The minimum ﬁrmware version is 422. Though updating to the latest ﬁrmware is recommended where possible.

These inverter/charger units must be connected to the Venus-device via the VE.Bus connection port.

1.4 All 48V VE.direct BlueSolar and SmartSolar MPPT Chargers are compatible

For proper operation, the Pylontech battery needs to be able to control the charge current. Therefor it is recommended to use Victron 48V compatible MPPTs models with VE.Direct port for charging.

MPPTs with a VE.Direct port

MPPTs are controlled via the Venus-device. Make sure the Venus-device runs v2.15 or later, and the MPPTs to 1.37 or the latest available version.

The MPPT requires connection to the Venus-device to regulate charge currents as the batteries require (due to temperature, etc) To test operation, try disconnecting the Venus-device from the MPPT. After a time-out, the MPPT will stop charging and ﬂash an error code on its LEDs. The error code is error #67: no BMS.

MPPTs with a VE.Can port

Use of VE.Can MPPT's with Pylontech batteries is not supported or documented.

2. Minimum Battery Sizing Recommendations

Each US2000B Plus battery module is approximately 50Ah at 48V, can provide 25A continuous charge and discharge and 100A peak for 1 minute.

The charge and discharge rates are managed automatically by the Pylontech battery and Venus-

device.

Using very large solar arrays with battery banks that are too small can exceed the limits of the batteries ability to charge and possibly lead to the BMS triggering over-current alarms.

You must have the minimum number of units to supply the potential current demand of the load connected to the inverter. It is more desirable to have the inverter/charger overload than the battery.

Some suggested battery sizings for common Victron inverter/chargers are listed below. These are suggestions for reliable operation for single phase oﬀ grid and are not speciﬁed by Pylontech.

3. CAN-bus Wiring

You can connect multiple battery modules together to form a single large battery by connecting the RJ-45 cable supplied by Pylontech using the link ports on the battery. This is shown in more detail in the example wiring diagram and Pylontech manual.

The batteries will automatically detect and link to each other, no adjustment of dip switches or software changes are necessary on the batteries.

The battery with the empty link port 0 is the master battery. Using the VE.Can to CAN-bus BMS type B Cable, part number ASS030720018, Plug the side which is labeled Battery BMS into the Pylontech CAN port of the master battery. Plug the side labeled Victron VE.Can into the Venus-device.
