About Us Working for Türkiye’s power continuity since 1978
At ELSİ Power Systems, we support business power continuity through our ELSIPOWER brand. Drawing on experience dating back to 1978, we combine carefully selected products with dependable after-sales technical services.
Power solutions backed by experience dating to 1978
Our expertise covers uninterruptible power supplies, voltage regulators, battery systems, rectifiers and inverters. We support our customers from site surveys and installation through to preventive maintenance and fault diagnosis.
From our headquarters in Beylikdüzü, our service network reaches all 81 provinces of Türkiye — protecting critical loads from industrial plants and data centers to healthcare facilities and commercial businesses.
“Even when the power goes out, your business keeps running.” We bring nearly half a century of experience to every project with the same care.
