Wiring a Single Battery
Pass the two positive battery cables in the HELIOS ESS Battery to Inverter Power Cable set (950-0070), from the inverter and through the conduit box.
Connect the lugs of these positive battery cables to the inverter’s positive battery ports.

On the battery, unscrew the battery terminal cover plates to access the positive battery terminals.

Connect the positive battery cable connectors to the positive terminals on the battery. Push the cable connectors against the receiving pins of the battery to secure the connections.
Repeat steps 1 to 4 for the negative battery cables (950-0070), connecting to the negative battery ports on the inverter and to the negative terminals on the battery.

Connect the CAT6 or higher communication cable that came with the HELIOS ESS battery to the inverter’s CAN port, and pass the other end of the cable through the conduit box to connect to the battery’s COM2 port (CAN port).
If setting up closed-loop communication without the LYNK II Communication Gateway (950-0025), and the HELIOS ESS battery is supplied with a termination resistor, insert the resistor into either the COM3 or COM4 port.
Re-attach the battery terminal cover plates.

For shipping purposes, the cover plate is attached inside-out. Please attach the cover plate so that it juts out and provides room for the battery and communication cables. |
