20kVA 3-Phase Online Uninterruptible Power Supplies

Pricing for a 20kVA 3-phase online UPS varies based on battery runtime, lithium-ion vs. VRLA chemistry, and installation complexity. Exact costs are not publicly listed; EdgeUptime provides a written quote based on site count and fleet size, with tiered service packages and Eaton pricing through the PowerAdvantage program.

An online (double-conversion) UPS, like the Eaton three-phase modular platforms at 20kVA, continuously converts AC to DC and back to AC, providing zero transfer time and the cleanest possible power. Line-interactive units, by contrast, only engage battery power during outages, making online systems the preferred choice for mission-critical 3-phase applications.

Standard VRLA batteries in a 20kVA UPS typically reach end of life within 3-5 years, depending on usage cycles, temperature, and load. Lithium-ion options, such as those in Eaton's online double-conversion platforms, offer longer lifecycles and faster recharge, reducing total maintenance and replacement frequency over the system's operational life.

Yes. Modular platforms like the Eaton three-phase modular platforms are designed to scale within data centers, industrial plants, and mission-critical facilities, allowing additional power modules to be added as load requirements grow without replacing the entire system, protecting your initial capital investment.

EdgeUptime provides structured maintenance records that support internal review, vendor oversight, continuity planning, and examination preparation including battery test records, maintenance logs, and executive uptime scorecards, supporting healthcare (Joint Commission, NFPA 99) and government audit requirements. This documentation is generated as part of ongoing managed monitoring and preventive maintenance services.

Support includes 24/7 emergency dispatch, quarterly preventive maintenance with battery testing and thermal scanning, remote managed monitoring with monthly reporting, and battery lifecycle management covering replacement scheduling, warranty management, and recycling, all backed by Eaton's published service guidance.
