Grid, metering and control · India
Transformers step voltage up from inverters and batteries to the grid, and down again for site loads. Solar and storage plants use inverter-duty transformers designed for the harmonics and load cycling that power electronics bring. The companies below make transformers in India.

A transformer's rating is often what limits how much battery and solar a site can add. Ingro EMS keeps the combined flow within the transformer's limit and can read its temperature alarms, so the plant uses its capacity fully without overloading it.
Ingro EMS is a made-in-India battery energy management system: one controller on site that runs battery storage, solar, diesel and the grid against your tariff, with a console and reports you can watch on a screen or your phone. It talks to equipment over open protocols such as Modbus TCP/RTU, CAN, IEC 61850 and IEC 60870-5-104, so it is not tied to any one brand on this list.
