About Yotta Energy
YOTTA ENERGY builds behind-the-meter energy storage and solar hardware for commercial buildings, and the software that runs it. Our batteries mount at the panel level under commercial PV arrays and are monitored and controlled through our gateways and cloud platform. We are now aggregating that fleet into Virtual Power Plants (VPPs): networks of customer-sited batteries and solar assets that the grid can dispatch as a single resource. Distributed storage like ours is one of the ways the grid absorbs new load, including the surge from AI and data centers, without waiting for new generation to be built.

• Experience managing and troubleshooting distributed fleets of Linux machine
