Indie Power Systems Microgrid Technology

Our Microgrid technology was internally designed from the ground up to provide everything required to manage a Microgrid. Owning all of the IP necessary to build a Microgrid system has enabled Indie Power Systems to become a one-stop-shop for a complete energy management solution. We design and manufacture each of the three basic components required to manage a Microgrid: 1) energy management software, 2) power electronics hardware, and 3) battery energy storage.
