2.0 DOCUMENTATION

This User Manual provides information about the integration of Rolls LFP lithium batteries with Victron Energy devices

in a closed-loop configuration using the LFP Connect gateway with installed LFP Connect Card for Victron. Rolls LFP

batteries may be used in Energy Storage System (ESS) for self consumption, grid-connected backup and off-grid

applications. These instructions apply to off-grid applications.

Note that in a Victron networked system the charging variables will be managed automatically by the Rolls LFP battery

BMS and the Venus GX / Color Control GX device. Discharging variables are managed by the set up of the Victron inverter.

3.0 OVERVIEW

3.1 System Overview

The LFP Connect gateway unlocks the full potential of a Rolls LFP lithium battery by enabling the internal

Battery Management System (BMS) to optimize the charge and discharge configurations of the world’s best inverter

chargers and solar charge controller systems in a closed loop configuration.

Rolls LFP lithium batteries must be set up to work with Power Conversion and Monitoring devices in either an

open-loop or closed-loop configuration. Rolls LFP battery charge and discharge settings in a open-loop configuration

are set up manually through the controller for the Power Conversion device at the time of installation. This is

commonly referred to as a ‘lead-acid drop-in replacement’ configuration. In a closed-loop configuration, the

battery charge and discharge rates and settings are dynamically controlled by the BMS of the Rolls LFP battery

over a connection with the power conversion devices in the network.

To connect with the communication network of a specific brand of inverter charger or solar charge controller,

the LFP Connect gateway requires an LFP Connect Card with the appropriate communication port.

3.2 Minimum Battery Capacity

Battery charge and discharge rates are managed automatically by the Rolls lithium battery and Victron CCGX

device. Using very large solar arrays with battery banks that are too small can exceed the operating limits of the

battery to charge and possibly lead to the BMS triggering over-current protection. Battery capacity must be sized

to accept the maximum charge current of the system, or the the charging devices must be curtailed to charge below

the operating limit of the installed batteries. This value is derived by adding together the charge capacities of all

inverter/chargers and solar charge controllers in the system. Additionally, battery peak capacity must be sized to

support the surge requirements demanded by the load attached to the inverter. Match the sum of all inverter peak

power values with the sum of all battery peak battery current values.

4.0 CONFIGURING VICTRON PRODUCTS

4.1 VE.Configure Settings

You will need the latest firmware on all connected devices. This section presumes familiarity with VEConfigure software.

These settings are for an off-grid application. These parameters once set will become the default values used

if communication with the Rolls LFP battery is interrupted for some reason. During normal operation the charge

characteristics are governed automatically by the CCGX via DVCC, with instructions from the connected Rolls LFP battery.

However it is necessary to set the discharging parameters for DC input low shut-down found under the Inverter Tab.

After setting the parameters, ‘send’ all parameters to the inverter and CCGX. Restart the CCGX after completion.

NOTE

Conﬁrm the Float Voltage after completing the installation of any Victron ‘Assistants’,

and if necessary reset the Float Voltage back to 26.8 V / 53.6 V.

5.0 INSTALLING & CONNECTING LFP CONNECT

TO THE VICTRON NETWORK

5.1 Installing the LFP Connect Card for Victron

The LFP Connect Card for Victron is a Slot 0 Type which only inserts into the left side slot on the bottom

of the LFP Connect gateway.

Slot 0 Type

NOTE

• The LFP Connect Card type to be used is determine by the brand of power

conversion equipment.

• If the LFP Connect Card is in the wrong slot, it will not function.

• If the LFP Connect Card is not ﬁrmly seated, it will not function.

5.2 Connecting LFP Connect to the Rolls LFP Battery

Connect the LFP Connect gateway to the Rolls LFP battery and power up as described in the Rolls LFP Connect

User Manual.

5.3 Connecting LFP Connect to the Victron Network

Before connecting LFP Connect to the Victron Network ensure that the firmware for all Victron devices is up to date.

• MultiPlus / Quattro - version 459 or later.

• CCGX / Venus GX - version 2.32 or later.

• VE.Direct MPPT - version 1.42 or later.

Insert one end of a CAT5 communication cable into the LFP Connect Card port and the other end into one (A) of the two

VE.Can ports (A-B) on the back of the Color Control GX (CCGX). Use the terminator provided with the CCGX to terminate

the network by plugging it into the second VE.Can port (B).

CAUTION

HAZARD OF ELECTRICAL SHOCK AND FIRE

• Do not plug the AEBus RJ-45 cable terminator into the 10/100 Ethernet port of the

LFP Connect gateway.

• Do not connect a CAT5 cable from the 10/100 Ethernet port of the LFP Connect to

the WAN or MODEM port of a network router.

• Turn OFF all devices before connecting cables or inserting an LFP Connect Card.

Failure to follow these instructions can damage equipment.

NOTE

• Power electronics are not AEBus devices and should not be connected to AEBus.

NOTE

• VE.Can MPPTs cannot be used and are not yet supported.

5.2 Connecting LFP Connect to the Rolls LFP Battery

Using the CCGX navigate from the Device List > Settings > Services > Can-bus Profile and select VE.Can & CAN-bus

BMS (250 kbit/s).

Return to the Device List and the CCGX should display Rolls LFP as one of the devices along with the battery

SOC, Voltage and Amps. If you have multiple batteries a single entry will show up, which represents all batteries.

The parameters option within the battery page shows the actual battery charge limits. If you have multiple

batteries a single entry will show up, which represents all batteries.

NOTE

• If Rolls LFP does not appear on the Device List, conﬁrm that the CAT5

communication cable is a normal patch type and not a cross over type. Use

manufactured cables to avoid bad crimps and reduce the risk of a poor connection.

NOTE

• Battery Low Voltage value displayed is the BMS value, the actual discharge

voltage limit is governed by the DC input low shut-down setting.

6.0 SYSTEM SET UP

6.1 Synchronizing the Victron System with the Rolls LFP Battery

Once the VE.Can and CAN-bus bit rate is set, communication of the Rolls LFP battery parameters will be automatic.

During normal operation, the charge parameter limits are set by the BMS of the Rolls LFP battery and communicated

through the system by the CCGX to the inverter/charger and MPPT.

To optimize performance of a Victron system the following items need to be manually set using the CCGX.

Navigate from the Device List screen > Settings > System Setup.

From the System Setup menu scroll down to select each item and then set as indicated.

• Battery Monitor: Rolls LFP on CAN-bus

• DVCC - Distributed Voltage and Current Control: ON

• SVS - Shared voltage sense: OFF(7)

• STS - Shared temperature sense: OFF

• Limit charge current: ON

• Max charge current: Installed number of Rolls LFP batteries x (S48-6650LFP: 92A < 130A) or (S24-2800LFP: 78 A < 110 A)(8)

(7) SVS should be set to OFF (there have been instances of conﬂict reported by Victron Support when SVS is set to ON and used with a Lithium BMS).

(8) Limit charge current works across the whole system. MPPTs are automatically prioritized over the mains. In case the Rolls LFP BMS requests a maximum
