Energy storage systems (ESS)

An energy storage system is the next step after a solar panel. The panel generates electricity while the sun is shining. An ESS stores it and supplies it when needed: at night, during grid outages, or during peak hours with high electricity rates. The Altek.ua catalog features industrial and commercial BESS systems with an official warranty and delivery throughout Ukraine.

Energy Storage System for Business

The instability of Ukraine’s power grid has made energy storage systems a practical tool rather than a luxury. An energy storage system for business ensures independence of production processes from power line failures and provides an opportunity to avoid peak electricity rates.

Industrial energy storage systems solve another important task: load balancing. A company with peak consumption in the morning and evening charges its battery bank at night using lower tariffs and discharges it during peak hours, achieving electricity cost savings of up to 30–40%.

What Is an ESS (BESS) and How Does It Work?

An ESS (Energy Storage System) is the term used internationally as BESS (Battery Energy Storage System). It is a modular complex consisting of battery modules, a Battery Management System (BMS), an inverter, and a control unit. It operates as follows:

• During periods of excess generation (sunlight hours or low-cost nighttime tariffs), the inverter charges the battery bank.
• During periods of energy shortage or grid outages, the battery bank discharges through the inverter to power the load.
• The BMS monitors each cell: temperature, voltage, and charge balance. In case of an anomaly, it disconnects the affected section without shutting down the entire system.
• The system integrates with solar panels, wind turbines, or the utility grid depending on the site’s configuration.

Key Features and Types of Energy Storage Systems

Key BESS parameters available in the Altek catalog:

• Battery chemistry: LiFePO4 (lithium iron phosphate) – the industry standard for industrial systems. Service life of 2,000–6,000 cycles, excellent thermal stability, and no ignition under overheating conditions.
• Capacity: from several kWh for residential systems to multiple MWh for industrial facilities. Modular architecture allows capacity expansion without replacing the inverter.
• Form factor: rack-mounted systems for server rooms and technical facilities, and containerized solutions for outdoor sites and industrial areas.
• Emergency switching time: less than 20 ms, unnoticeable for most loads.

These are the key criteria to consider when making a selection today.

Who Is an Energy Storage System Suitable For?

Battery energy storage systems are in demand in several scenarios:

• Manufacturing facilities – protection of production lines from power disruptions and optimization of electricity costs through peak load management.
• Medical institutions and data centers – critical loads that cannot tolerate even short-term outages.
• Agricultural enterprises and greenhouse complexes – uninterrupted power supply for irrigation, ventilation, and lighting systems.
• Commercial real estate – shopping centers, office buildings, and hotels where power outages result in direct financial losses.

This ensures a reliable energy reserve for any situation.

Energy Storage System (BESS): How to Choose the Right One?

Three parameters determine the choice of an energy storage system:

1. Discharge power – how many kW the system can supply to the load simultaneously. It should cover the facility’s peak demand with a safety margin.
2. Capacity – how many kWh can be stored. This determines the autonomy time at a given load. Calculation formula: load (kW) × desired runtime (hours) ÷ 0.8.
3. Integration with existing infrastructure – compatibility with the grid operator, ability to connect solar panels or wind turbines, and monitoring protocols (Modbus, CAN).
