PV301L: Solar Training - Solar Electric Lab Week (Battery-Based)

COVID-19 (Coronavirus) may affect your travel plans, please click here to read SEI’s response plan and current information regarding registrations and cancellations.


Safely install, test, and commission battery-based PV systems in this solar training workshop. Lab stations are comprised of both stand-alone and grid-tied with battery back-up systems, and include both AC and DC coupled systems. Integrating generator back-up will also be covered. Participants will concentrate on battery safety, wiring, and maintenance, and will wire balance of system components including: combiner boxes, disconnects, power centers, controllers, battery banks, and inverters. Set-up, basic programming, and testing of components for specific battery-based applications will be integrated into the lab sessions. Students will learn fundamental procedures for safe installation and commissioning practices, and all exercises will have an emphasis on battery safety considerations.

what you will learn

Students who complete the PV301L workshop will be able to:

  • Identify and describe the basic functions of each component in a PV system
  • Describe the configuration of various types of PV systems: PV direct, Stand–alone, PV/hybrid, Multimode, Zero-sell, Micro-grid, Utility-scale energy storage
  • Calculate the capacity & voltage of different batteries
  • Determine the state of charge of a battery by testing voltage and specific gravity
  • List safety precautions & equipment required to work with batteries

  • Wire and program battery SOC meters in different PV system configurations
  • Set up and operate batteries during bulk, absorption, float, and equalization cycles
  • Describe how maximum power point tracking and voltage step-down affect a PV system
  • Identify some features, options, and metering available on different types of battery chargers
  • Identify appropriate inverter types for different battery-based system configurations
  • Compare available features and capabilities of battery-based inverters
  • Identify specifications critical for battery-based inverters
  • Wire test and program battery based inverters
  • Discuss when and why breakers would be used rather than fuses
  • Use a 3-line diagram to wire a system
  • Discuss the order and perform safe installation practices
  • Demonstrate the order of safe commissioning
  • Demonstrate the order of shut-down and how to establish an electrically safe working environment
