Govt Mandates OEMs Under PM Surya Ghar to Connect Inverters to National Servers Specified by MNRE
Ministry of New and Renewable Energy (MNRE) has mandated all inverter OEMs under the PM Surya Ghar Muft Bijli Yojana to connect their inverters directly to government-managed national servers, aiming to safeguard grid stability and energy data sovereignty.

The Ministry is in the process of finalising the detailed vendor neutral and open communication protocol based data communication and security guidelines for rooftop solar (RTS) monitoring and control through the National Portal which will be made available for integration testing of Inverter communication devices from September 1, 2025, notified MNRE.
“All inverter communication devices/dongles/data loggers deployed under the scheme shall have Machine-to-Machine (M2M) SIM communication protocol to enable secure and reliable data transmission,” it said.
The move is to address cybersecurity and grid stabilisation challenges that is posed by the integration of the targeted one crore RTS plants with a cumulative capacity of 30 GW. “Inverter communication modules that transmit data to servers outside India not only pose risks of unauthorized control but also threaten national energy sovereignty by exposing sensitive consumption and generation data,” reasoned MNRE in a notification.
It further added that millions of inverters communicating with third party OEM servers can be exploited to manipulate inverter operations, potentially leading to coordinated disruptions in power generation and grid instability.
“Multiple rounds of deliberation have been done with major stakeholders to implement a framework to track generation benefits of RTS installations as well as for the centralisation of RTS data on a National Software Platform hosted on servers located in India and managed by MNRE or any other Government Agency to ensure monitoring and control of millions of inverters aggregating GW of capacity remains with Government agencies considering Grid Security and Stability,” it said.
