OTA refers to the method of wirelessly transmitting updates and patches to devices in a network without the need for direct interaction or physical access. In the context of energy management, this could involve anything from updating software for energy meters, grid management systems, to solar power controllers and battery storage solutions. OTA updates allow these devices to remain at the cutting edge of technological developments while reducing downtime and maintenance costs. The shift toward OTA in energy management has accelerated the deployment of smart, scalable solutions in modern energy systems.
