Energy Power Solutions
EMS
Why Our Own System?
In the current market, we lacked a solution corresponding to our ideas.
We managed to assemble a team of experts with experience from various fields (especially in the field of IT and energy), we connected them and developed our own Energy Management System (EMS), which is suitable for larger installations with the possibility of customization for each customer.
We have thus developed a system for managing energy sources that you can control from anywhere on Earth, it is Cloud native and API first - we have the option of connecting third-party software through our application interface, this facilitates communication with other systems that the customer already uses.
Management takes place on several levels
Low EMS level
- Communication and control of internal states in battery storage
- Batteries, inverters, contactors, heating, cooling, electronic fire system, temperature sensors etc.
- Battery storage safety features
- Control via PLC in predefined or last settings
High EMS level
- Data analysis and collection, historical data, more advanced analyses
- Visualization for the client
- Selecting the mode and changing the behavior parameters of the battery storage
- Active management of battery storage
- Local and Cloud storage
- Database with possibility of own control and setting of functions
SCADA
The main tool of our EMS system is SCADA (Supervisory Control And Data Acquisitio), thanks to which we can offer clear and easy management of all our technologies with integrated graphs and analyzes of any device from anywhere in the world.
It is within our competence to connect to an already existing SCADA system or to another control system. We can thus obtain valuable information from already installed technologies as well as from completely new technologies (for example, BESS, PV...) and then combine these information to create an overall picture of the state of all devices and their parameters.
We offer the possibility of controlling our systems and the systems of our partners, or the possibility of controlling your existing systems using our SCADA.

What functions of BESS together with the EMS system will you appreciate the most?
Peak Shaving
Whenever additional machines are turned on during production that require high power for a short period of time, it will also be reflected in the electricity bill. Battery storage provides additional energy thus covering short-term peaks in consumption. You can then reduce the power capacity that you have reserved with your energy provider and save money.
- Reduction of reserved power capacity
- More self-sufficiency
- Reduction of penalties for exceeding consumption limits Suitable for industrial companies, especially manufacturing and energy-consuming companies.
Timed Peak Shaving
Peak shaving with a time schedule that determines how the battery storage will be charged/discharged according to known data or according to the weather. The PLC then discharges/charges the batteries according to the requirement of the layout window, however, even in this mode peak shaving has priority, so that the customer never exceeds his quarter-hour maximum again.
Uninterrupted Mode
Production backup similar to a UPS. In the energy system there are inverters running separately at the input and at the output and the battery storage is in between. This function will be used by customers who work, for example, with sensitive devices or substances (robotic production, chemical production). If you don't have a need for a completely transition-free system, we can offer a solution that works with a transition within milliseconds.
Black Start
The so-called blackout can threaten both consumers and the power plants themselves (if they do not have an island operation mode). For power plants, BESS can become a third source of energy that can be used in the event of a failure of the main and backup power supply. A power outage thanks to BESS can be a momentary outage that affects operations only minimally. For consumers, BESS can be the only backup source that offers energy to restore appliances immediately. The storage is able to start itself without an external grid.
Frequency Regulation
The frequency in the grid can fluctuate outside the specified range. The BESS system is capable of charging and discharging at power level, installed power level or according to preset combinations of operating modes. With these actions, the frequency is returned to the required range in real time (within seconds).
Power Factor Regulation
The main purpose of reactive power compensation is to reduce the apparent power taken and to reduce the current passing through the mains. Therefore, compensation is one of the important cost-saving measures that reduce the load on the mains, thereby reducing losses and increasing the lifespan of the mains.
Voltage Regulation
The voltage in the grid can fluctuate due to various influences. BESS is able to automatically regulate the voltage by charging and discharging the batteries. For power producers, battery storage increases the device's resistance to adverse effects that come from the central grid.
Island Mode
In places where there is insufficient coverage of the electrical grid, a combination of an electric energy source (PV) and a battery (BESS) can be used. Surplus electrical energy is stored in the batteries at a time when the production exceeds consumption (for example, when the sun is shining and the consumption is not so high). This energy is consumed at a time when, on the contrary, the consumption is higher than what the connected source is able to produce.
Primary/Secondary Regulation
We are able to meet the conditions of the power balance system (mFFR, aFRR).
Load leveling
Thanks to automatic balancing, the customer becomes a constant load - the consumption curve is balanced
