What Is Jinko SunTera G3
Jinko SunTera G3 is the new generation of large-scale containerized energy storage systems from Jinko ESS. A standard 20-foot container houses 6.25 MWh of battery capacity, increasing BESS energy density without increasing the container’s external dimensions.
The system is designed for generation-side, grid-side, and user-side applications, including renewable energy storage, energy shifting, peak shaving, load management, grid support, and large industrial microgrids.
SunTera G3 features high-capacity LFP cells, active balancing, intelligent liquid cooling, and a comprehensive protection architecture covering every level, from individual battery cells to the entire system.
What’s New in Jinko SunTera G3
6.25 MWh in a Single Container:
SunTera G3 increases the capacity of a standard 20-foot container to 6.25 MWh, enabling more stored energy per unit of site area.
New 587/588 Ah LFP Cells: High-capacity cells increase the system’s energy density and reduce the number of internal components.
System RTE ≥95%: Advanced system control and active balancing help improve the efficiency of the energy storage and discharge cycle.
Temperature Difference ≤2.5 °C: The intelligent liquid cooling system maintains a more uniform temperature across battery cells, which is important for BESS stability and service life.
Improved Deployment: Jinko states that more than 90% of pre-commissioning preparation is completed at the factory, reducing the amount of work required on-site.

What Makes Up a BESS Based on SunTera G3
SunTera G3 is the battery DC block of an energy storage system. To create a complete BESS, the battery unit must be integrated with power conversion and control equipment.
A typical large-scale BESS architecture includes:
Jinko SunTera G3 → PCS → transformer equipment → switching and protection equipment → EMS → point of connection.
If a solar power plant operates at the site, the EMS coordinates the operation of the solar power plant + BESS + grid + facility load.
Ekotechnik Ukraine selects system components and architecture according to the technical requirements and the parameters of the point of connection.
Applications of Jinko SunTera G3
Industrial facilities: Energy storage, peak shaving, load optimization, and energy consumption management.
Large-scale solar power plants: Storing excess solar generation, energy shifting, and reducing renewable energy curtailment.
Grid-scale BESS: Large-scale energy storage facilities operating on the grid side and supporting power system stability.
Microgrids: Coordinating BESS, solar power plants, generators, and loads through an EMS.
Energy shifting: Shifting electricity use between different time periods.
Peak shaving: Covering peak power demand using stored energy.

Industrial Solar Power Plant + Jinko SunTera G3
One of the key applications of SunTera G3 is integration with a large-scale solar power plant.
In this configuration, the solar power plant supplies the facility’s current electricity demand, while available surplus generation can be directed to charge the BESS. The stored electricity is used later according to the EMS control algorithm.
This helps increase the share of solar energy consumed on-site, enables energy shifting, and supports management of the facility’s energy balance.
Ekotechnik Ukraine delivers comprehensive turnkey solar power plant + BESS + EMS solutions, including solar panel installation, solar power plant installation, solar inverters, batteries for solar power systems, and energy storage systems.
6.25 MWh Is Capacity, Not Power
The 6.25 MWh rating indicates how much energy a single SunTera G3 container can store.
BESS power is measured in MW and determines how quickly the system can charge or discharge the stored energy.
SunTera G3 can be deployed in 0.5P or 0.25P configurations. The final AC power output of a project is determined by the PCS, transformer equipment, number of containers, and grid connection parameters.
MW = power
MWh = stored energy

❓ FAQ — Frequently Asked Questions
How much does Jinko SunTera G3 cost in Ukraine?
The cost of SunTera G3 and a complete BESS project depends on the number of containers, the 0.5P or 0.25P configuration, PCS capacity, EMS, transformer equipment, logistics, and the scope of installation work. Ekotechnik Ukraine provides individual cost estimates based on the requirements of each project.
What is the capacity of Jinko SunTera G3?
The nominal capacity of one SunTera G3 container is 6.25 MWh.
What is the power output of SunTera G3?
6.25 MWh is the battery’s energy capacity. BESS power is determined by the system configuration, PCS, and number of containers. SunTera G3 supports 0.5P and 0.25P configurations.
What does 0.5P mean in a BESS?
0.5P means that the system’s nominal power is approximately half of its energy capacity per hour. This configuration is used for BESS systems with an approximate two-hour discharge duration. The final parameters are determined by the project design.
Can SunTera G3 be used with a solar power plant?
Yes. SunTera G3 is designed for use in energy storage systems with renewable energy sources and can be integrated with a solar power plant through an appropriate AC or DC architecture.
How many containers are required for a 25 MWh BESS?
Four SunTera G3 containers have a combined nominal capacity of 25 MWh. PCS power and other equipment are determined through a separate engineering assessment.
Can SunTera G3 operate in a microgrid?
Yes. The SunTera series can be used in large-scale microgrid solutions, with an EMS coordinating the BESS, solar generation, diesel generators, and loads.
Does Ekotechnik Ukraine provide turnkey BESS solutions?
Yes. Ekotechnik Ukraine provides engineering and equipment selection, equipment supply, design, installation, integration, and commissioning of industrial energy storage systems.
