For estates, coastal homes, new builds, renovations and second homes where an outage or a surge costs more than an inconvenience.

Who it is for

Which homes need whole-home battery backup?

Homes that depend on technology need it most. If your house runs on a network, lighting control, shades, a theater, security and climate systems, a single outage can knock all of them offline at once. A RoseWater HUB keeps them running with zero transfer time and protects them from surges and unstable power every day.

Signs your house has a power problem include flickering or dimming lights, screens that blink, equipment that needs rebooting and LED bulbs that fail early. Outages are only the part you notice. Build a Power Plan to see what your home would need.

Homes we protect

What kinds of homes do we work on?

Six kinds of home get the most out of a HUB. Each one has a different reason to want power that never drops.

Estates

Large homes run on lighting processors, shade motors, networks, theaters, wine rooms and wellness spaces. A HUB40, or more than one HUB, keeps all of it on clean power so a storm is not followed by a week of service visits.

Coastal homes

Homes on the water see wind, salt and lightning, and often sit at the end of long utility lines. The HUB rides through outages with no gap and carries surge protection rated for repeated lightning strikes.

New builds

The easiest time to plan a HUB is before the drywall. We work with your builder and architect on the room, the electrical design and a separate budget line for power, so nothing gets squeezed in later.

Renovations and retrofits

You do not need a new house. More than half of RoseWater's installations go into existing homes, connecting at the main electrical panel in a garage or basement.

Second homes on the Cape and Islands

When nobody is there, an outage can mean a warm wine room, a failed sump pump or a security system that went offline. The HUB keeps those systems running and sends alerts to you and to us.

Solar panels on the roof of a New England home

Homes with solar or a generator

A HUB accepts up to 10 kW of solar through RoseWater's SBX10 and works with one or more generators. We coordinate with your solar installer or generator contractor so the pieces work as one system.

What stays on

What can a HUB keep running?

Anything on the circuits it serves. RoseWater's planning worksheet lists 21 kinds of load, and you choose which ones matter. These are the ones that come up most often.

Network, Wi-Fi and internet
Lighting control and shades
Control4, Savant, Crestron or Lutron processors
Home theater and distributed audio
Security cameras and alarm
Refrigeration and wine storage
Smart plumbing and sump pumps
HVAC controls
Home healthcare equipment
EV charging and outdoor kitchens on larger systems

The systems

Which system fits your house?

Your electrical service is the starting point. A 100 A service usually points to a HUB20, a 200 A service to a HUB40, and a 208 V three-phase service to a RoseWater 3-phase system. Very large homes may use several HUBs.

FAQ

Questions from homeowners

Is a RoseWater HUB only for new construction?

No. More than half of RoseWater's installations are retrofits in existing homes. The HUB connects at your main electrical panel, and a licensed electrician makes the connection.

Where does the HUB go in the house?

Indoors, usually in a garage or basement. Plan on a space about 3.5 feet wide, 3 feet deep and 8 feet high, plus 36 inches clear in front for service. It does not need air conditioning. The HUB40 can also go outdoors in RoseWater's weather-resistant enclosure.

Can I back up the whole house?

Often, yes. Whole Home protection uses one or more HUBs, sometimes with a generator, sized to your service and your loads. Many owners start with the systems that matter most and add storage later. The Power Plan helps you decide.

How will I know it is working at my second home?

The HUB has built-in remote monitoring. You can see outages, voltage events and battery status, and alerts can go to you and to us. The HUB also beeps on site when the batteries run low.

How long will the batteries last in an outage?

It depends on what the system is carrying. Run time is calculated for your home in the Power Plan and confirmed during design, and adding a generator or solar extends it. RoseWater rates the batteries for a usable life of 7 to 10 years.

What should stay on in your house?

Build a Power Plan for your home in a few minutes. We review it, confirm sizing on a site visit, and design a RoseWater system around the way you live.
