One outage, four systems at risk
High-rise buildings depend on continuous power to keep occupants safe and moving. A single grid outage puts four things at risk at once:
Elevators stop
When grid power drops, elevators can strand occupants between floors and cut off egress for upper-level residents and tenants.
Life safety offline
Fire pumps, smoke control, and stairwell pressurization depend on continuous power to protect occupants and meet code.
Water stops flowing
Domestic water booster pumps lose pressure to upper floors, while sump pumps stop — risking flooding in mechanical spaces.
Access & comfort lost
Security systems, access control, lighting, and HVAC go down, disrupting tenants and building operations.
Automated systems need power too
Modern high-rises run on automated systems that all depend on continuous power — not just the systems above, but the layer of building automation and security that operators rely on every day:
Physical security
Cameras, access control readers, and intrusion detection all need continuous power to keep watching and controlling every entry point.
Access control & entry
Electronic locks and card readers fail-safe or fail-secure when power drops — risking locked-out residents or unsecured doors.
Building automation
Centralized HVAC, lighting and elevator control systems stop responding without continuous power to the building management system.
Communications & alarms
Intercoms, fire alarm monitoring and emergency communication systems depend on the same continuous power.
The Flux Home solution
Flux Home is a solid oxide fuel cell that runs continuously on natural gas to generate primary electricity, paired with battery storage for instantaneous, seamless power — independent of the electrical grid. The process is straightforward: natural gas feeds an electrochemical conversion in the fuel cell stack, battery storage buffers the output for an instant response with no gap, and the building gets continuous uptime for elevators, life safety and water systems alike.
Beyond standby power
Diesel generators and battery-only UPS systems wait for the grid to fail before they respond. Flux Home is already running as the building's primary source, with battery backup for instant continuity:
| Diesel Generator / UPS | Flux Home | |
|---|---|---|
| Role | Emergency-only backup | Primary power, battery-backed |
| Response to outage | 10-60 second transfer delay | Seamless — battery buffers instantly |
| Runtime | Limited by onsite fuel or battery | Continuous, sized to the building |
| Noise | 70–85 dBA typical | < 45 dBA at 10 ft |
| Maintenance | Frequent testing, oil changes | Minimal moving parts |
| Emissions | Combustion exhaust | No combustion, no flame |
Sized for high-rise critical loads
Flux Home and Flux Ember are right-sized for the building — from a single riser to whole-building critical load.
Flux Home — single riser or small building critical loads
Ideal for elevator machine rooms, single-riser life-safety loads, or a dedicated mechanical closet.
Flux Ember — whole-building or multi-tower critical load
Packages generation, battery storage, and thermal recovery in one transportable unit for rooftop or grade-level mechanical yards.
Built for the building site
Compact and quiet enough for a mechanical room, rooftop, or loading dock:
120 VAC nominal voltage, up to 40 A current, ~600 lbs, indoor/outdoor rated. Deployed in a mechanical room, rooftop mechanical yard, or loading dock — no new gas service required where natural gas is already on site. Output and fuel consumption vary with site conditions, gas quality and system configuration.
Reliable, visible, in control
Flux Home is a dispatchable, standards-compliant asset built for critical building infrastructure:
- Remote telemetry — Wi-Fi-based monitoring keeps building operators and facilities teams connected to every unit.
- Real-time diagnostics — continuous performance monitoring flags issues before they cause downtime to critical systems.
- Dispatchable operation — operators retain visibility and control of every deployed unit across the property.
- Open, interoperable control — built to integrate with open standards such as UDMI (Universal Device Management Interface), keeping the building vendor-neutral.
Certifications & compliance: UL 1741 (inverter safety for grid support), UL 9540B (battery safety compliance), and EN 50465 (electrical compatibility standard).
