Design of Off-Grid Systems Part 2: System Design

An appropriately designed off-grid system is one that balances the cost of implementing and operating the system with its ability to reliably meet the energy needs of the users. This can be challenging given the relatively large uncertainty of most load estimates. In this webinar, we described basic approaches to off-grid system design, including the use of international standards and computer-aided simulation. We covered important practical considerations when selecting inverters, charge controllers and battery banks. This video webinar featured Dr. Henry Louie, Co-founder of Kilowatts for Humanity.

Watch this recorded video to learn:

  • the lifecycle of an off-grid project, from a pre-feasibility study to expansion or retirement
  • how to design an off-grid system using standards- and computer-based approaches
  • what to look for (and avoid) when selecting system components
