India is moving to keep rooftop solar telemetry on India-based servers to protect data leakage, as the Ministry of New and Renewable Energy advances a national, vendor-neutral data layer for inverters under the PM Surya Ghar program, which targets 10 million homes and 30 GW of capacity. The draft framework standardizes how inverter-side devices authenticate and publish data to a centralized platform, aiming to mitigate cyber risk and enhance grid visibility. The push is framed around energy sovereignty, amid concerns that some monitoring dongles and loggers have been routing data to overseas servers.
