## In This Guide

## Chapter 01 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.

**Figure 1** — Inline pass-through: the LiFe² battery connects to Nexus CAN 1, and the internally linked CAN 2 connects on to the approved inverter or MPPT.

## Chapter 02 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](https://docs.aerl.cloud).

## Chapter 03 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](https://docs.aerl.cloud) .
3. Confirm the LiFe² data appears in AERL Cloud.
