Role:JOB DESCRIPTION
Role and Responsibilities
Solmacher Solar Energy is looking for a technically competent and detail-oriented BESS Project / System Engineer to support the engineering, integration, testing, and commissioning of Battery Energy Storage Systems (BESS) for solar PV, hybrid power (PV + BESS + Diesel Generator), and other energy storage applications.
The successful candidate will be involved throughout the project lifecycle, from system sizing and technical design reviews to equipment procurement, site installation, system integration, and commissioning. The role requires a strong understanding of electrical power systems, battery storage technologies, safety requirements, and coordination across multidisciplinary engineering teams.
Key Responsibilities:
BESS System Design & Engineering
Develop and review BESS system configurations, including battery capacity (MWh), power rating (MW), discharge duration, and integration requirements.
Review Single Line Diagrams (SLDs), electrical schematics, equipment layouts, cable routing, and technical design packages.
Evaluate technical submittals for Battery Management Systems (BMS), Energy Management Systems (EMS), Power Conversion Systems (PCS), inverters, transformers, switchgear, and auxiliary systems.
Coordinate BESS integration with solar PV systems, diesel generators, microgrids, and other power sources.
Technical Compliance & Safety
Ensure designs and installations comply with applicable project specifications, local regulations, and relevant international standards, including NFPA 855, UL 9540, UL 9540A, UL 1973, and IEC 62619, as applicable.
Review battery thermal management systems, HVAC or liquid-cooling solutions, fire detection and suppression systems, and emergency shutdown arrangements.
Coordinate with suppliers, consultants, and safety specialists to address technical risks and system safety requirements.
Testing, Commissioning & System Integration
Review, coordinate, and witness Factory Acceptance Tests (FAT), Site Acceptance Tests (SAT), and commissioning activities for BESS equipment, including battery racks, Battery Management Systems (BMS), Power Conversion Systems (PCS), and Energy Management Systems (EMS).
Oversee BESS pre-commissioning activities, including equipment inspections, electrical testing, protection system verification, communication checks, and readiness for energization.
Coordinate BESS installation testing, initial energization, start-up, shutdown, synchronization, and commissioning in accordance with approved procedures and manufacturer requirements.
Verify battery charging and discharging operations, State of Charge (SoC), State of Health (SoH), power output, energy capacity, round-trip efficiency, and overall system performance against contractual guarantees.
Coordinate integration of BESS with Solar PV systems, diesel generators, SCADA, EMS, microgrid controllers, and plant monitoring systems to ensure seamless hybrid power plant operation.
Verify communication interfaces, data exchange, control commands, alarms, and protection signals using Modbus RTU/TCP, CAN bus, and other applicable industrial communication protocols.
Conduct functional and integrated system testing, including charge/discharge modes, power control, load sharing, peak shaving, energy management, grid synchronization, and backup operation, as applicable to the project.
Verify the functionality of BESS safety and protection systems, including emergency shutdown (E-Stop), fire detection and suppression, gas detection, thermal management, alarms, and protective interlocks.
Support site performance testing, troubleshooting, identification of technical defects, corrective action coordination, and resolution of commissioning issues.
Coordinate final performance verification, commissioning reports, punch-list closure, as-built documentation, O&M manuals, operator training, and technical handover to the client.
Project Execution & Site Coordination
Prepare and review Method Statements (MOS), inspection and test plans, technical procedures, and commissioning documents.
Coordinate with civil, structural, electrical, and mechanical teams on foundations, equipment placement, cable containment, earthing, and installation interfaces.
Review vendor drawings, material submittals, technical documentation, and operation and maintenance manuals.
Resolve technical queries, Requests for Information (RFIs), non-conformance reports (NCRs), and engineering changes.
Monitor engineering deliverables, procurement activities, and technical milestones to support project schedules and quality requirements.
Preparing of Monthly Power Performance Monitoring Report to track BESS performance
Qualifications and Education Requirements
Bachelor’s degree in Electrical Engineering, Mechanical Engineering, Renewable Energy Engineering, or a related discipline.
3–7 years of relevant experience in BESS, solar PV, hybrid power systems, power generation, or industrial electrical infrastructure.
Practical experience with containerized lithium-ion BESS, preferably LFP or NMC battery technologies.
Experience in engineering design reviews, equipment technical evaluations, system integration, testing, or commissioning.
Experience coordinating with equipment manufacturers, suppliers, consultants, subcontractors, and project teams.
Relevant training or certifications in BESS, electrical safety, commissioning, or energy storage system safety is a plus.
Experience with utility-scale solar PV and BESS hybrid projects. is a plus.
Exposure to FAT/SAT witnessing, site commissioning, and performance testing.
Preferred Skills
Good understanding of MV/LV electrical systems, transformers, switchgear, protection relays, and earthing systems.
Familiarity with BMS, EMS, PCS, SCADA, battery thermal management, and fire protection systems.
Ability to interpret SLDs, electrical schematics, equipment layouts, and technical specifications.
Knowledge of relevant BESS safety standards and grid or microgrid integration requirements.
Proficiency in AutoCAD and Microsoft Office, particularly Excel.
Familiarity with ETAP, MATLAB/Simulink, PVsyst, Primavera P6, or similar engineering and project management tools is an advantage.
Strong technical reporting, problem-solving, communication, and coordination skills.
