Built to Fit Your Home
Most home backup systems are bulky boxes that force you to make space. Sierro is built to fit your home by reducing overall volume — not just thickness.
FusionCore™ Tech & Industrial-Grade LFP
20+ Years of Reliable Power
Rated for 8,000+ cycles — delivering 2× the lifespan of standard power station.
Battery Technology
Industrial-Grade Energy Designed for Homes
Sierro is built on a simple belief: reliable energy shouldn’t be a luxury. We bring industrial-grade LFP technology — normally used in large-scale energy systems — into a compact home backup.
FusionCore™
Smarter integration for a safer, smaller, and rock-steady system.
Utility-grade cells mean longer life and consistent power for years.
Relentless Safety
Uncompromising Safety, Inside & Out.
True reliability means surviving both internal heat and external hits. We engineered Sierro to exceed strict industry standards, so it is safe enough for the bedroom and tough enough for the real world.
†Cycle-life and lifespan statements are based on specified battery test conditions and one equivalent cycle per day. Actual service life varies with use, temperature, load, and charging behavior.
Seamless Backup Power
Instant Auto-Switch UPS
When the grid goes down, Sierro switches instantly—in under 15 milliseconds. Your refrigerator, WiFi router, NAS, and computer stay on without interruption, protecting sensitive electronics from resets or hard shutdowns.
Ultra-Quiet
Sleep-Friendly Silence
Designed for the quietest spaces in your home, Sierro operates at under 25dB during typical essential loads—quiet enough for bedrooms and home offices.
‡Measured under specified light-load test conditions. Fan noise can increase under heavier loads or higher ambient temperatures.
Solar charging
Recharge Beyond the First Night
Longer outages require more than stored power. With compatible MPPT solar input up to 300W and car charging support, Sierro helps extend backup beyond the first night.
Up to 300WMPPT solar input, 12–55V

Frequently asked questions
What devices can Sierro 1000 power?
Sierro 1000 can power common plug-in devices such as refrigerators, freezers, televisions, monitors, laptops, routers, lamps, chargers, and pet care equipment when the combined running and startup load stays within its 500W rated output.
Can Sierro 1000 power a refrigerator?
Yes, when the refrigerator's running and startup wattage are within the 500W rated output. Compressor startup requirements vary, so check the appliance label or manufacturer specifications before unattended use.
Does it require an electrician?
No. Sierro 1000 is designed for selected plug-in devices and connects to a properly grounded household outlet. It is not a whole-home electrical system.
Does UPS passthrough use the battery during normal AC operation?
No. When utility power is available, Sierro powers connected devices through AC passthrough while keeping the battery ready. The battery takes over only when input power drops, so normal standby use does not continuously cycle the battery.
Can it charge from solar?
Yes. Sierro 1000 supports compatible solar charging up to 300W within a 12–55V input range. Solar performance varies with panel output, weather, and setup conditions.
Can it power my whole house?
No. Sierro 1000 is designed to keep selected essential devices running, not to replace a permanently installed whole-home backup system.
