PV Electrical System Design: Inverters, Circuits, and Energy Storage
About the Course:
This advanced PV Electrical System Design microcredential prepares PV technicians and designers to configure complete electrical systems for solar installations, including inverter selection, circuit sizing, protection systems, and energy storage integration. Students will gain hands-on skills in designing string configurations, applying voltage drop calculations, selecting appropriate conductors and raceways, and integrating battery technologies and module-level electronics. The course also explores backup systems, arc-fault protection, and performance optimization strategies for hybrid and AC-coupled systems.

- Perform string size and AC circuit sizing calculations to ensure safe, code-compliant designs.
- Understand module-level power electronics (MLPE) and their use in complex roof geometries or shaded environments.
- Calculate voltage drop across conductors and apply NEC limits to minimize energy losses.
- Compare conductor types, insulation ratings, and ampacity requirements for PV circuits.
- Apply raceway selection criteria based on material type, fill capacity, and environmental conditions.
- Identify integrated protection components such as disconnects, fuses, and rapid shutdown devices.
- Understand arc-fault detection and mitigation strategies in PV system design.
- Compare battery chemistries, including lithium-ion and lead-acid, for solar storage applications.
- Evaluate charge controller types (PWM vs MPPT) and their application in various system designs.
- Understand AC-coupled systems and their components, including inverters, transfer switches, and load panels.
- Perform energy storage system sizing using load analysis, autonomy requirements, and efficiency losses.
- Estimate auxiliary and backup power requirements for critical loads and emergency power systems.
