Connecting the Nexus to the CAN Bus

These instructions apply to any AERL-approved CAN bus product (battery, inverter, MPPT). Once the Nexus is on the CAN bus, it finds the approved devices and handles their communications automatically: there is nothing to configure on the battery or inverter for monitoring.

The Nexus has two CAN ports that are internally linked, so it can sit directly on the existing CAN bus between your AERL-approved products. Connect it one of two ways:

Option 1 — Inline Pass-Through (Preferred)

Insert the Nexus inline on the CAN bus. Because CAN 1 and CAN 2 are internally linked, existing communications keep flowing through the Nexus:

• Battery → Nexus CAN 1
• Nexus CAN 2 → approved inverter / MPPT

See Figure 1 for this arrangement.

Option 2 — Endpoint with Termination Plug

The Nexus has no built-in termination. If it sits at an end of the CAN bus, connect one CAN socket to the bus and fit a 120 Ω RJ45 termination plug in the other.

Getting Online

Once the Nexus is on the CAN bus, it handles the rest. Plug in Ethernet, power it on, and claim it in AERL Cloud. For detailed AERL Cloud setup instructions, see docs.aerl.cloud.

Quick Checklist

1. Connect the Nexus to the CAN bus either inline (CAN 1 from the battery, CAN 2 to the inverter/MPPT), or at the end of the bus with a termination plug.
2. Get the Nexus online and claim it in AERL Cloud — see docs.aerl.cloud.
3. Confirm the LiFe² data appears in AERL Cloud.
