The Xtreme Power Conversion M90S-6S and the APC Smart-UPS Modular Ultra SRYL10K15XLT18 are modular, true online, double-conversion UPS systems designed to protect mission-critical IT, network, and edge-infrastructure loads.
While both platforms provide scalable architectures and integrated service features, the M90S-6S delivers higher usable power at the 12 kW level, significantly longer internal runtime, and more granular local diagnostics, making it better suited for higher-density deployments without immediate reliance on external batteries.
10–12 kW Modular Online UPS Comparison
| Feature | XTREME POWER M90S-6S (12 kW) | APC Smart-UPS Modular Ultra SRYL10K15XLT18 | XPCC Advantage |
