The industrial energy storage system iONTEC500K828 is a ready-made solution for projects with a power of 500 kW and a nominal capacity of 828 kWh, designed for customers in the renewable energy sector, professional energy sector, and industry. The Energy Storage is delivered as a "turnkey" solution, meaning the delivery of a complete system including installation, commissioning, and, if required, technical documentation.

Features of the iON industrial energy storage system:

• Changing the energy profile, e.g., shifting loads in time and using electricity when its cost is lower.
• Providing power quality services – voltage and frequency stabilization.
• Operation in off-grid mode – ensuring system operation in case of power outages (UPS).
• Ability to provide flexibility services for distribution networks, e.g., participation in demand-side response (DSR) programs.
• Optimization of energy from photovoltaic, wind, and other generation sources.
• Protection against the inability to export electricity to the grid.
• Battery sections made with the safest LiFePO₄ technology.
• Available in two versions: outdoor containerized and indoor.
• Fully adapted to work in Polish climatic conditions thanks to container insulation.
• Equipped with a modern and environmentally friendly fire suppression system, continuously sampling air in the container, which, upon detecting electrolyte particles, can prevent uncontrolled temperature rise and spread of danger by injecting nitrogen and displacing oxygen from the container.
• Advanced EMS (Energy Management System) produced by NRG PROJECT, operating according to a protocol adapted to OIRE (Energy Market Information Operator) and CSIRE (Central Energy Market Information System). It allows managing system components and meeting the requirements of typical energy storage applications.

Components of the iON industrial energy storage system:

• NRG500K828 battery
• Kehua bidirectional converter BCS 500 K-A
• Kehua on/off grid switchgear BTS 1000 K-S
• EMS energy management system
• 40 ft container

Features of the energy storage components:

1. Kehua bidirectional converter (BCS):

• Integrated isolating transformer – ensures complete isolation of the battery from the power grid.
• Bidirectional converter – charges and discharges the batteries.
• Includes additional charging modes, such as constant current charging, equalization charging, and buffer charging.
• Off-grid operation – advanced islanding detection technology.
• Adapted to work in smart grids.
• Reactive power compensation.
• On/off-grid switching time for general conditions <200ms.

2. Kehua on/off grid switchgear (BTS):

• Suitable for use in microgrid systems.
• Enables peak load shifting and emergency power supply.
• Fast disconnection of the system from the power grid (switching time <10ms).
• No need for additional microgrid control system configuration.

3. NRG battery section:

• High-voltage (HV) battery.
• Made with the safest LiFePO₄ technology.
• Capacity of 828 kWh.
• Intelligent BMS system of Polish production.

4. EMS energy management system:

• Optimization of energy consumption.
• Limiting energy feed-in from generation sources to the grid.
• Operation according to an hourly schedule.
• Voltage stabilization.
• Frequency stabilization.
• Load profile change.

SOLFINITY and NRG PROJECT

iONTEC is a brand of Solfinity's own products (switchgear, mounting structures, and energy storage systems). The series of industrial energy storage systems was created in collaboration between Solfinity and NRG Projekt. The system represents a comprehensive offer in the energy sector. iONTEC was designed based on the best power electronics equipment. The new brand offers the most popular energy storage sizes in the industrial segment, from 50 kW to 1000 kW of nominal power and capacities from 138 kWh to 1104 kWh – LiFePO₄ battery sets.

Please note that the selection of the industrial energy storage system iONTEC always requires free technical consultations. The delivery time for each order is subject to individual agreement. The estimated delivery time after project details are agreed upon is approximately 26 weeks.
