Solar Electric Systems Project Supervisor (SEI) Many supervisors underestimate questions on utility interconnection standards and arc-flash hazard calculations. The SEI exam heavily weights photovoltaic system design integration with existing electrical infrastructure, where candidates routinely confuse NEC Article 690 requirements with general commercial standards. Sharp focus on dc disconnect sizing and ground-fault protection nuances separates passing scores from borderline attempts.
