3.1 Battery Wiring
Open the BMS and all Battery wiring panels. Screws are located on the rear right side.
2.3 Battery Bracket
1. Secure battery bracket on top of Battery1.
2. Mark mounting holes on wall.
3. Remove mounting bracket from Battery1 and drill
out the holes.
4. Reinstall the battery bracket and secure to Battery1.
5. Secure mounting bracket to wall using appropriate
mounting hardware. Lag bolts and wall anchors
provided.
2.5 EI BMS Installation
1. Place the BMS on the top of Battery1.
2. Secure the BMS with M4 Screw on left and right side.
Note: This step is provided for reference.
Continue to the EI Inverter Quick Start
Guide to proceed with the rest of the
installation. Come back to this step once
the EI Inverter and EI Link have been
installed.
Battery1 is the battery that connects to the EI BMS.
2. Connect the BMS to EI Inverter Charging
Cables to the BAT+ and BAT- ports on the
BMS.
3. Connect the other end of the BMS to EI
Inverter Charging Cables to the
corresponding BAT+ and BAT- ports in
the EI Inverter.
4. Connect one end of the BMS
Communication Cable (RJ45 ends) to the
BMS port and the other end to the EI
Inverter BMS port.
5. Connect BMS and EI Link grounding
terminals with a properly sized (installer
made) grounding cable.
6. Tighten the BAT+, BAT-, and
communication cable connectors using
the provided tightening wrench.
7. Place the wire protector ring around the
BAT+. BAT-, and COM cables and then
snap the ring into the BMS upper
knockout.
2.4 Extension batteries (if applicable)
1. Follow the same procedure as above to install the
battery base and the wall mount bracket.
2. Install the two smaller cover brackets on top of the
battery module.
3. Press down and secure the top cover onto the
battery.
Note: Ensure all prior steps are completed before making electrical connections.
