LFP Connect gateway unlocks the full potential of a Rolls LFP LiFePO4 battery by enabling the internal Battery Management System (BMS) to optimize the charge and discharge configurations of the world’s best residential inverter-chargers and solar charge controller systems.
LFP Connect provides closed-loop communications for adaptive interaction between the Rolls LFP battery and power conversion electronics turning a good system into a great one with up to 25% improvement in 0% to 100% SOC recharge time.
LFP Connect enables remote display and reporting of battery system-level status through supported third-party web portal and cloud monitoring services.
LFP Connect Installation
Choose a clean, dry, easily accessible indoor location. All the communication ports on the LFP Connect are accessible from the bottom of the device when mounted on a wall or DIN rail. Clearance of at least 50 mm (2 inches) below the device is needed to allow for the bend radius of cables connected to the LFP Connect.
LFP Connect Mounting Options
A Wall Faceplate, for use with a gang box, and a Surface Mount Bracket is included. The gang box is not included. Place the LFP Connect behind the mount, insert M3 screws through the holes into threaded inserts on the face of LFP Connect and secure. Secure all cables to prevent them from becoming damaged. Two threaded inserts on the back of LFP Connect can be used to attach a 35mm DIN Rail mounting clip. DIN Rail hardware is not included.
LFP Connect Card Installation
With LFP Connect disconnected from all devices insert the LFP Connect Card in the correct slot. Ensure it is firmly seated into the internal connecting slot. Replace covers after mounting LFP Connect Card.
Connecting LFP Connect to AEbus
Using a CAT5 cable insert one end into the AEbus RJ45 port located on the bottom of LFP Connect. Insert the other end of the CAT5 cable into the AEbus port located on the battery. If there are multiple Rolls LFP batteries, series network them together and insert the end of the CAT5 from LYNK into the LFP Connect at the end of the series network, as shown below.
LFP Connect requires a 12-volt power source. Connect the fly leads of the included DC-DC AEbus power converter to the positive and negative battery terminals of a Rolls LFP battery. Insert one end of a CAT5 cable into the RJ45 port of the DC-DC AEbus power converter and then insert the other end into the last AEbus Y-Connector, as shown below.
Connecting LFP Connect to Power Conversion Electronics
Instructions on networking with specific power electronics are found in the relevant LFP Connect Card Manual. Refer also to the specific power electronics guides for system configuration information.
HAZARD OF EQUIPMENT DAMAGE
- Do not plug an AEbus RJ-45 cable terminator into the 10/100 Ethernet port of the LFP Connect.
- 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 will damage equipment.
Note: Power electronics are not AEbus devices and should not be connected directly to AEbus.
