Frequently Asked Questions: UPS Systems for Large Homes and Estates
What is a UPS and why do I need one in a residential home?
A UPS (Uninterruptible Power Supply) provides backup power and power conditioning to keep your home’s systems running when the utility grid fails or fluctuates. In large, tech-enabled homes, a UPS is essential for protecting automation systems, AV equipment, security, and critical infrastructure.
How is a UPS different from a whole-home battery backup?
A typical home battery (like those used in solar storage systems) provides backup power but does not condition the power. A true UPS like the M90S-12S delivers online double-conversion protection, ensuring clean, regulated power even during brief surges or sags—ideal for sensitive electronics.
What kinds of systems can a residential UPS protect?
The M90S-12S protects systems such as:
- Smart lighting and automation controls
- Home theaters and entertainment centers
- Security cameras and surveillance systems
- Climate control and HVAC systems
- IT networks, home offices, and servers
- Wine rooms, elevators, gates, and more
How long can the M90S-12S run my home during a power outage?
With optional extended VRLA battery modules, the M90S-12S can provide up to 6 hours of runtime at full load. For partial loads or critical systems only, runtime can be extended even further.
Does the M90S-12S support split-phase 240/120V power?
Yes. The M90S-12S supports both 240/120V split-phase and 208/120V single-phase configurations, making it ideal for U.S. residential electrical systems.
Is this system compatible with generators?
Yes. The M90S-12S can be integrated with a home generator to provide seamless power continuity. It delivers stable power while the generator ramps up, avoiding dips and spikes during transfer.
Where is the UPS installed in a home?
The system is typically installed in a mechanical room, utility room, or AV/control closet. It has a low acoustic profile and compact footprint, making it suitable for indoor residential use.
Can I expand the system later?
Absolutely. The modular design of the M90S-12S allows you to start small and scale up—adding more power modules or battery modules as your needs grow.
