Green Knowledge is Power

The old saying “knowledge is power” couldn’t be truer when it comes to going green. The ELM FieldSight app not only provides information about how your system is performing, but also gives you insight into how much energy you are using and where it is coming from. Our goal is to give you the power to actively and positively impact your carbon footprint.

Our Native iOS and Android App gives you the full insight of your microgrid system in the palm of your hand. Not only does it provide you the status of your ELM energy storage system, but also the health status of your utility grid, solar array and/or generator.
