Description
APC Smart-UPS Modular Ultra SRYL5K20XLT18 — 0kVA Lithium-Ion Scalable Modular On-Line UPS
The SRYL5K20XLT18 is APC's top-tier enterprise modular UPS at 0kVA capacity. Where traditional monolithic UPS units require full-system replacement for capacity expansion or battery refresh, the Smart-UPS Modular Ultra (SRYL) platform makes both possible without taking the UPS offline. Power modules, battery modules, and backplates are all hot-swappable and field-installable.
Modular Architecture — What It Changes
Monolithic UPS units force decisions at procurement: how much capacity do I need today, plus how much growth do I expect over 5-7 years? Buy too little and you face a forklift upgrade. Buy too much and capital is tied up in unused capacity. The SRYL modular architecture solves this by separating capacity from chassis: start with the modules you need today, add capacity as load grows, replace aging battery modules individually rather than swapping entire cabinets.
Lithium-Ion Battery Technology
Built-in lithium-ion battery modules deliver up to 10-year service life — roughly 2-3x the lifespan of traditional VRLA lead-acid batteries. The practical result: fewer scheduled maintenance windows, lower lifetime battery replacement costs, and significantly reduced facility weight loading vs. equivalent lead-acid configurations.
Key Features
- Hot-Swappable Power Modules: Add capacity or replace failed modules without taking the UPS offline.
- Scalable Battery Architecture: Internal modules plus external battery cabinets — runtime scales independently from capacity.
- N+1 Redundancy Capable: Configure additional modules for redundant operation; tolerate module failures without load impact.
- Lithium-Ion Battery Modules: 10-year service life, faster recharge, wider operating temperature range, dramatically lower lifetime maintenance.
- AP9643 Network Management Card 3 Included: SNMP v3, web/CLI, EcoStruxure IT integration, environmental monitoring out of the box.
- Field-Configurable Backplate: Match output outlets to site-specific requirements without separate SKUs.
- True Double-Conversion On-Line: Continuous inverter operation, zero transfer time, full isolation from utility events.

Enterprise Power Architecture — Start with a Conversation
Modular UPS deployment is a multi-decision process: capacity planning, redundancy configuration, battery module count, maintenance bypass requirements, backplate outlet selection, and integration with existing building management systems. Questyme has worked with data center architects, healthcare facilities engineers, and government IT directors to deploy modular UPS systems aligned with both operational and procurement requirements.
