Since the 1980s, the founders of ESI have designed and implemented complete energy solutions for smart-home clients. These clients needed clean, uninterrupted power to keep their complex systems working and their family safe, regardless of the circumstances. Using this knowledge, ESI created the BAMTM Micro-Grid, which provides constant, clean, efficient, and resilient electricity independent of the status of the public grid. ESI is committed to providing consumers with energy solutions that are unmatched in the home and light commercial markets.
