MNRE Issues Draft Guidelines for Solar Battery Approval for conducting testing in test Labs

The Ministry of New and Renewable Energy (MNRE) has issued draft guidelines for series approval of various storage batteries—lead-acid, lithium-ion, and nickel-based—to standardize performance testing under the Bureau of Indian Standards (BIS) registration process. These guidelines define a “product family” based on shared design and construction elements, ensuring compliance with the national standard IS 16270:2023, which covers secondary cells and batteries used in solar photovoltaic (PV) systems.
