Trusted Performance
Hospital-grade power, now for the home
The same Xtreme Power technology trusted in hospitals, data centers, and government facilities is now available for high-end residential projects. With professional startup and warranty services, you can rely on the M90S-12S for years of uninterrupted protection.
Unlike generators, the M90S-12S provides instant, silent backup power with zero transfer time. There’s no fuel, no noise, no exhaust, and no waiting for startup — just clean, stable power that’s safe for sensitive electronics and smart-home systems.
Can the M90S-12S power my entire home?
Yes. The modular design scales from 6 kW to 48 kW, covering everything from essential loads to full luxury estates. Many homeowners back up the entire home — AV systems, select lighting, security, and entertainment — for true peace of mind.
How long will the UPS run during an outage?
Runtime depends on load and battery configuration. The M90S-12S can provide up to 6 hours at full load with extended battery cabinets; for lighter loads, runtime extends significantly longer.
What maintenance is required?
It’s low maintenance compared to fuel generators. The front-access modular design makes battery or module swaps quick and easy, and there’s no fueling or regular servicing required.
How does it integrate with a smart-home system?
The UPS delivers clean, stable power that keeps smart devices, automation controllers, and sensitive electronics online. It features a color touch LCD for local monitoring, plus optional remote monitoring for full visibility.
What is the warranty?
The M90S-12S includes a 3-year parts warranty (electronics and battery) plus 2-year on-site labor, with 5×8 startup support (USA and Canada). Coverage can be upgraded to 3-year, 7×24, and additional extended options are available.
Is professional installation required?
Yes. The M90S-12S is a high-capacity system designed for integration with your home’s electrical infrastructure.
