The Ministry of New and Renewable Energy (MNRE) has mandated that all original equipment manufacturers (OEMs) enlisted for the supply of inverters under the PM-Surya Ghar: Muft Bijli Yojana to integrate inverter communication devices with the programme portal.
This decision follows concerns that inverter communication devices were transmitting data to servers located outside India, raising the potential risk of grid disruptions. All such devices must also be linked to software managed by the MNRE or any other designated agency. The integration process will begin with a testing phase from September 1, 2025. According to the guidelines, all inverter communication devices, dongles, and data loggers must operate on machine-to-machine SIM communication protocols to ensure secure and reliable data transfer. Additionally, MNRE has issued draft guidelines for remote monitoring systems (RMS) and inverter communication devices under the scheme. These aim to establish a secure and multi-layered protocol to ensure reliable data capture and transmission from rooftop solar installations. RMS devices must be registered using their international mobile equipment identity number and must support secure communication transport layer security or secure sockets layer protocols.
