SWELECT has a strong financial base, high quality assets, and deep customer trust. With a proven market leadership for two decades in UPS under Numeric brand, SWELECT is fully geared to provide the reliable BESS systems the renewable energy industry needs. I look forward to driving profitable business growth while addressing the interests of all stakeholders—customers, employees, and investors.”
