Responsibilities:

• Commissioning Planning: Lead commissioning (Cx) efforts for PV, BESS, and microgrid projects from planning through execution with minimal supervision; develop and manage commissioning plans (sequence, resources, timelines) and coordinate across internal and project teams to ensure successful delivery.

• Electrical System Testing and Verification: Conduct comprehensive testing of electrical systems, including PV arrays, inverters, BESS components, switchgear, and microgrid controllers, to ensure compliance with design specifications and performance standards.

• Mechanical Systems Testing (Supporting Role): Support commissioning and validation of mechanical components (e.g., HVAC for BESS enclosures, thermal management systems) to ensure full system integration and performance.

• Functional Testing: Perform functional tests to validate the operation of individual components and subsystems, such as PV panels, inverters, battery banks, switchgear, and protective relays, both independently and as part of the integrated system.

• Performance Evaluation: Assess the performance of PV systems, BESS, and microgrids under various operating conditions, analyzing data to identify potential issues and optimize system efficiency.

• Troubleshooting and Diagnostics: Investigate and resolve MEP issues encountered during commissioning, utilizing diagnostic tools and techniques to identify root causes and implement corrective actions for inverters, switchgear, and other critical components.

• Interconnection Compliance: Ensure compliance with regulatory requirements and utility interconnection standards for PV systems and BESS, facilitating the approval process and coordinating with relevant authorities as necessary.

• Safety Compliance: Adhere to strict safety protocols during commissioning activities, including lockout/tagout procedures, arc flash mitigation, and personal protective equipment (PPE) usage, to minimize risks to personnel and equipment.

• Documentation and Reporting: Maintain accurate records of commissioning activities, test results, and equipment specifications for inverters, switchgear, and other critical components, and generate comprehensive reports to document findings and recommendations.

• Training and Support: Provide training and technical support to operations and maintenance personnel, imparting knowledge of system operation, maintenance procedures, and troubleshooting techniques for inverters, switchgear, and other critical components.

• Integration and Optimization: Collaborate with design engineers and project managers to ensure seamless integration of PV, BESS, and microgrid components, including inverters, switchgear, and other critical electrical components, and participate in optimization efforts to enhance system performance and reliability.

• Quality Assurance: Implement quality assurance processes to verify that installations meet industry standards, manufacturer specifications, and project requirements for inverters, switchgear, and other critical electrical components, conducting inspections and audits as needed.

• Customer Liaison: Serve as a primary point of contact for clients and stakeholders during commissioning activities, addressing inquiries, providing status updates, and resolving issues related to inverters, switchgear, and other critical electrical components to ensure customer satisfaction.

• Ability to travel as needed to support operations and perform other duties as required.
