Ennovation Technology is your partner specializing in the production of energy storage systems, which are a crucial component of the energy transition. Our mission is to participate in this process and contribute to a future that is environmentally friendly and powered by green energy. Replacing coal-fired power plants with renewable energy sources requires stabilizing the grid. One of the key elements for achieving this is energy storage systems (ESS), which offer the opportunity to optimize energy costs, connect to renewable energy sources, and minimize the risk of blackouts.
Energy storage systems can be built in various configurations and using different technologies, depending on the specific requirements of applications. Currently, the majority rely on lithium-ion battery cells. They are equipped with an Energy Management System (EMS), inverter, and battery system, which can be configured according to customer requirements in terms of power ranging from 50 kW to several MW and in terms of energy capacity from 100 kWh to several MWh. The modern EMS system utilized enables our devices to perform numerous functionalities. Depending on the expectations, battery modules are closed in rack cabinets or in maritime and specialized containers.
The technology developed in Ennovation Technology’s devices ensures, with proper use of the storage system, the stability of the batteries for up to 6,000 cycles and comes with a 5-year warranty.

Energy Management System (EMS)
Energy Management System, or EMS, is a key tool in controlling and monitoring energy flows, and consequently, the savings or revenues from proper management of energy consumption in an enterprise.
The EMS keeps the user informed about its operating parameters and tasks performed. The energy storage can implement various control strategies such as:
- Obtaining revenue on price spree (e.g., dynamic tariffs)
- Obtaining revenue from the power market (e.g. DSR or generation)
- Increasing self-consumption
- Reducing distribution charges by reducing the value of contracted capacity
- Feed-in power supply
- System services (e.g., frequency regulation)
- Reactive power compensation
- Zero Export function
- Island operation (off-grid)
EMS system view
The topology of a company’s energy system can vary in terms of loads as well as energy demand profile. The key elements of the architecture are:
- Energy connection (the most relevant parameters are contracted power and connection power)
- Equipment, technological processes, i.e. the nature of the load, and in fact the profile of energy consumption and power demand
- RES (Renewable energy sources), most often in the form of photovoltaic installations
- Energy storage or other energy source
