Our Partners
At Celestix Industries India Pvt. Ltd., we manufacture MC4 connectors, solar MC4 connectors, PV connectors, photovoltaic connectors, IP67 solar connectors** engineered to IEC 62852 and UL 6703 standards, built for solar photovoltaic (PV) installations requiring high‑reliability solar DC connectors, PV cable connectors, and renewable energy connectors. Using zinc‑plated copper contacts and UV‑stabilized PPO/PC housings, our connectors ensure low‑resistance DC transmission and long‑term outdoor endurance.
Our advanced precision moulding and solar connector manufacturing systems, PV connector assembly processes, MC4 cable assembly capabilities, automated assembly systems, and multi‑stage QC allow us to deliver consistent quality to global OEMs, EPC solar companies, combiner box manufacturers, and PV cable assembly producers.
