Install the BMS 

To install the BMS to manage up to four EI batteries: 

1.

 

Place the BMS on the top-most battery underneath the link. 

2.

 

Secure the BMS using the provided M4 screws on the left and right side. 

 

3.

 

Open the wire box doors on the right side of the BMS and the battery. 

4.

 

Use the tightening tool to tighten connections and install ring protectors on knockouts. 

 

To connect the BMS to the inverter: 

1.

 

Strip 15mm of insulation off each of the battery charging cables (found in the BMS box) 

and crimp on their Phoenix Contact MC4 connectors.   

      

2.

 

Connect one end of the prepared battery charging cables to their respective inverter 

BAT ports and the other end to the BMS BAT ports.
