Device integrations
Pylontech
The Pylontech LEMS in the Voltmasters EMS: one or more high-voltage racks as a single BMS over Modbus TCP, paired with a separate PCS.
Our EMS connects to the Pylontech LEMS controller (Local Energy Management System), which presents one or more high-voltage racks as a single system, over Modbus TCP.
Supported devices
| Model | Role |
|---|---|
| LEMS | BMS for 1500 V class battery racks, for example the PowerCube-M5A |
How the integration works
The EMS reads the aggregated state of charge, state of health, voltages, currents, power limits, cell diagnostics and rated capacity from the LEMS.
The battery is added as a stand-alone BMS device. Charging and discharging go through a separate PCS, for example the Sinexcel PWS1-1725KTL-H, within the power limits the LEMS reports.
