Comprehensive testing solutions for all solar energy system components



Solar inverter testing is mandatory under India's BIS Compulsory Registration Scheme (CRS). Our lab conducts comprehensive solar inverter testing as per IS 16221 (Part 1 and Part 2) for both grid-connected and off-grid photovoltaic inverters.
As a BIS-recognized solar inverter testing lab in Faridabad, ITC Lab assesses solar inverters across critical electrical, safety, and performance parameters. This includes conversion efficiency at multiple load points, total harmonic distortion, anti-islanding protection, grid synchronization behavior, and dielectric strength. Our NABL-accredited test reports are accepted for BIS CRS registration, which is required before solar inverters can be legally sold in the Indian market.
Solar storage batteries are the backbone of off-grid and hybrid solar power systems. ITC Lab offers the most thorough solar battery testing in India, covering capacity, cycle life, safety, and performance under actual operating conditions - making us the preferred solar testing lab for battery manufacturers and solar system integrators.
Whether you manufacture lead-acid solar batteries, lithium-ion storage packs, or flow batteries for solar PV applications, our accredited solar battery testing services deliver precise and reliable results as per IS 16270:2023 and other applicable standards. Our testing scope covers electrochemical performance, electrical safety, and environmental durability - ensuring your product is field-ready, compliant, and bankable for project financing purposes.
