Simple integration with Nilar

If you are looking for an alternative to lead and lithium-ion batteries that promises safe and powerful performance, without being detrimental to the environment, the Nilar Energy series offers the ideal products.

Batteries for all applications

We realize that applications can be different and, therefore, offer a versatile battery. The modularity of the the Nilar Energy series allows configurations of voltages from 192 to 600 V, giving you the solution that your customer needs without compromise.

Easy communication and control

The Nilar energy storage solutions support several communication interfaces together with an advanced software that monitors the batteries down to every module. The energy storage system can be configured to perform several different tasks, giving you the best solution for your needs.

Modular energy storage solutions

Nilar offers a multitude of solutions to fit many applications and locations. An energy storage system ready to be connected to the grid requires several components that handle monitoring, control and conversion. Nilar Home Box, Cabinets and Racks contain our BMS and Nilar battery packs with a built-in Integrated Monitoring Unit (IMU). In addition, a Power Conversion System (PCS) is required in order to convert the battery current from DC to AC. This will then connect the Home Box, Cabinet or Rack to the electrical grid. Lastly, an EMS that can control and coordinate several energy systems may be of use in select applications.

Energy Management System

An Energy Management System (EMS) is a higher-level system that monitors, controls and optimizes the performance of the energy system. The EMS communicates with the BMS and the PCS and can command these systems to charge or discharge the batteries using different signals. The signal descriptions can be found in the Nilar Function Description, which is provided upon request.


The Power Conversion System (PCS) converts the DC power of the batteries to the desired voltage and frequency of the surrounding energy system or electrical grid. The PCS is the primary controller of when the battery is charged or discharged, as it controls the current flows in and out of the energy storage.


The standard communication interfaces supported by the BMS are Modbus TCP/IP and Modbus RTU. In custom integrations, communication via CANopen is also available.

System configurations

The Nilar Energy products can be connected to the electrical grid using either an EMS controlled PCS or a BMS controlled PCS. The type of configuration is decided by which component controls the operation of the energy storage. The operation can be controlled by an external EMS or by an external EMS through the BMS. An AC/DC PCS, often called an ‘inverter’, is required to connect the energy storage to the grid. We can assist you upon request to find the correct PCS to match your energy storage system. This PCS can then be controlled by the Nilar BMS or by an external EMS.

EMS controlled PCS

Our EMS controlled PCS configuration is an open integration where the customer has control over the EMS. The EMS then communicates with the PCS and BMS.

BMS controlled PCS

The BMS controlled PCS configuration has a BMS controlled PCS. The customers EMS then communicates with the BMS which relays the commands to the PCS.
