Battery Energy Storage Systems
Engineering · Integration · EPCSolart engineers and delivers battery energy storage systems for utility-scale, industrial and hybrid energy projects. Our scope covers the battery system, PCS, EMS, electrical infrastructure, grid connection and commissioning.
We work with established battery and power-conversion technology partners and adapt the system architecture to the project, grid connection and operating requirements.
01 // BESS APPLICATIONS
The required battery power and energy capacity depend on the grid connection, operating strategy, site constraints and commercial model. We design the complete system around those parameters rather than starting from a fixed product.
Battery storage for grid balancing, ancillary services, energy shifting and other utility-scale applications. System architecture is developed around the available connection point and required operating profile.
Behind-the-meter storage for industrial facilities where load profile, contracted capacity, power quality or backup requirements justify battery integration.
Hybrid plants combining photovoltaic generation with battery storage. The BESS can be designed around an existing or planned point of interconnection.
02 // ENGINEERING SCOPE
BESS projects require coordination between battery technology, power conversion, electrical infrastructure, controls, protection and the grid connection. Solart covers the interfaces between these systems.
Our engineering scope can include the complete electrical and control architecture of the project. The exact scope is defined according to the project stage, connection requirements and EPC responsibility.
Battery containers, LFP systems, BMS, HVAC, fire detection and associated auxiliary systems.
PCS selection and integration, operating modes, protection interfaces and control architecture.
Transformers, MV switchgear, cable systems, protection, metering and substation interfaces.
Plant controls, energy management, monitoring, remote communication and operational interfaces.
Technical coordination with the relevant DSO or TSO, protection concept, metering and commissioning requirements.
03 // PROJECT TYPES
We work with developers, investors, industrial companies, EPC contractors and project owners at different stages of development.
Suitable where the project is being developed around a specific grid node, land parcel and target MW/MWh configuration.
Existing transformers, cables, switchgear and connection capacity are assessed before defining the storage architecture.
Solart can support the technical development, equipment procurement, electrical engineering, EPC coordination and commissioning of an investment project.
For landowners, local developers and project partners, BESS can be developed together with the required grid, permitting, engineering and investment structure.
04 // TECHNOLOGY & SUPPLY
Solart is not tied to a single battery platform. We select battery, PCS and control technologies according to project requirements, availability, technical compatibility and commercial conditions.
The battery itself is only one part of a bankable BESS project. Our engineering work connects the selected equipment to the electrical infrastructure and the requirements of the grid operator.
05 // DELIVERY
The engineering sequence depends on the maturity of the project. Existing grid approvals, land, permits and equipment selections can be incorporated into the scope from the start.
Location, target MW/MWh, grid connection, available land, application and project stage are reviewed to establish the technical scope.
BESS architecture, battery and PCS selection, transformer sizing, MV/HV topology, EMS and fire-safety requirements are defined.
Connection requirements, protection, metering, technical documentation and coordination with the relevant DSO or TSO are addressed.
Detailed electrical documentation, equipment procurement, supplier coordination and preparation for construction and commissioning.
Site coordination, electrical installation, testing, protection settings, SCADA/EMS integration and grid synchronisation.
Handover documentation, warranty coordination, monitoring, maintenance and long-term technical support can be included according to the project scope.
06 // STARTING A PROJECT
You do not need a completed BESS specification before contacting us. We can work from the available project information and define the technical architecture from there.
07 // BESS FAQ
Yes. Depending on the project, Solart can coordinate equipment procurement together with the engineering and EPC scope. We work with established battery and power conversion manufacturers and select the equipment according to the project requirements.
Yes. The engineering scope can be structured around an equipment supplier already selected by the developer or investor. In that case we coordinate the required electrical, control, protection and grid interfaces.
Yes. MV/HV infrastructure is part of Solart's broader electrical engineering and EPC scope. Depending on the project, this can include transformers, switchgear, cable systems, protection, metering, SCADA interfaces and grid connection engineering up to 110 kV.
Yes. Existing PV plants can be assessed for BESS integration. The available grid connection, transformer capacity, protection concept, metering and operating requirements determine the appropriate architecture.
Yes. Solart works with project owners, developers and investors on technical development, co-development and EPC structures. Where appropriate, BESS projects can be developed together with the required grid, permitting and investment structure.
LFP is currently the main chemistry used for the containerised BESS systems we evaluate because of its combination of cycle-life characteristics, thermal behaviour and commercial availability. The final technology selection is project-specific and depends on duration, power, operating profile, safety requirements and commercial conditions.
Grid requirements are defined by the relevant network operator and project location. Solart coordinates the BESS electrical and control architecture with the applicable connection requirements, protection, metering, communication and commissioning procedures.
