The EnerTech 15kVA 1:1 Phase Solar Online UPS delivers continuous, high-efficiency power protection engineered for sensitive IT infrastructure, healthcare facilities, and mission-critical commercial equipment. Built on true online double-conversion technology with an intelligent DSP-based MPPT controller, it maximizes solar energy harvest up to 98% while slashing electricity utility bills. The system guarantees instantaneous zero transfer time (0 ms) between solar, battery, and utility grid power, preventing system crashes during unpredictable blackouts. It outputs a highly regulated pure sine wave (220V/230V/240V ±1%) and isolates connected loads from all grid transients, surges, and electrical noise. Engineered for maximum storage flexibility, it supports both Lead-Acid and Lithium-Ion battery banks with advanced battery charging management. Complete with an interactive front LCD display, robust overload/short-circuit protections, and an industrial-grade enclosure rated up to IP55, it ensures dependable, eco-friendly operational continuity.
