> Pylontech integration within our EMS

Our EMS supports utility-scale battery systems from Pylontech.

Pylontech specializes in lithium battery storage systems for residential, commercial, and utility-scale applications.

The integration connects to the Pylontech LEMS (Local Energy Management System) controller, which presents one or more high-voltage battery racks as a single system. The EMS reads the aggregated state of charge, state of health, voltages, currents, power limits, cell diagnostics, and nominal capacity directly from the LEMS over Modbus TCP.

### Supported devices

We support the following Pylontech systems:

**LEMS**

-   **LEMS controller** fronting 1500 V-class battery racks (e.g. **PowerCube-M5A**)

The battery is integrated as a standalone BMS device and pairs with a separate PCS (e.g. the [Sinexcel PWS1-1725KTL-H](https://voltmasters.io/en/docs/device-integrations/battery-systems/sinexcel/)) for charge and discharge control.

### EMS functionality

With the current integration, our EMS enables:

-   Live monitoring of state of charge, state of health, voltages, currents, and cell temperatures
-   Charge and discharge power envelopes based on the limits reported by the LEMS
-   Intelligent charging and discharging of the connected battery through the paired PCS
-   Peak shaving, load balancing, and demand response
-   Optimization of solar self-consumption

Additional functionality may be added over time as integration capabilities evolve.
