# Nexus EMS

The Brain of Your Hybrid Power System

01 **Control** Every source, battery and load

02 **Integration** Every brand, one system

03 **Protection** Battery and equipment first

04 **Oversight** Every decision on record

## One Site. One Controller.

Nexus Lite · Nexus 4G · Nexus HMI

Nexus EMS is an energy management system (EMS) that runs a whole hybrid or off-grid site. It sits above the device controllers and makes the energy decisions for all of them: on site, offline if need be, with no custom PLC programming.

### Works with

| Type | Equipment | What Nexus EMS does |
|---|---|---|
| Solar charge controllers | AERL CoolMax SRX and SRX-R | Aggregates CCL and CVL and monitors operation |
| Batteries | AERL LiFe², AERL Kakadu 120, Solinteg, Pylontech | Reads its limits and keeps the site within them |
| Inverters | Solinteg M2HT (AERL All-In-One), Selectronic SP PRO, Deye, CE+T, XESS | Starts and stops, sets charge and discharge, supervises |
| Generator controllers | Deep Sea Electronics, ComAp, DEIF, Woodward | Sets mode, starts and stops, resets alarms |
| Meters and outputs | Modbus energy meters, Nexus 4G relays, Modbus remote I/O | Reads meters, switches relays |

**Preliminary information.** Functions and supported equipment are subject to change; confirm availability with AERL. Nexus EMS decides about once a second: fast protection, synchronising, breaker control and required export limits stay with each device. It protects equipment and is not a functional safety system.
