Authorized RoseWater Energy Dealer Whole-Home Battery Backup
When the grid fails, a RoseWater Energy system keeps your house running with zero transfer time. The lights stay on, the network stays up and nothing has to reboot.
What is Boston Backup Power?
What does a power outage do to a smart home?
Nor'easters and ice storms
Wind, heavy snow and ice bring down lines across New England every winter. Outages can run for hours or days, and a house with a generator still goes dark for about 10 to 30 seconds before it starts.
Summer lightning and surges
A nearby strike or a utility switching event sends a spike down the line. Equipment that survives one big surge can still be worn down by years of smaller ones.
Everyday sags and flicker
Most power problems never make the news. Brief sags, brownouts and electrical noise make lights flicker, screens blink and systems reboot for no clear reason.
How does a RoseWater HUB keep the house on?
Zero transfer time
The HUB is always carrying the house. It runs as an always-online double-conversion system with no transfer switch, so when the grid drops there is nothing to switch and no gap to notice.
Industrial surge protection
Non-sacrificial, commercial-grade lightning and surge protection is rated by RoseWater for up to 40 strikes of 140,000 volts, on the grid feed, solar input and standby power.
Voltage regulation and noise filtering
Every circuit on the HUB gets steady 120 V, 60 Hz power with total harmonic distortion under 3%, whether the source is the grid, the batteries or a generator.
Battery, solar and generator in one system
Standard battery storage is 28.8 kWh, expandable. The HUB accepts up to 10 kW of solar through RoseWater's SBX10 and works with one or more generators.

Which RoseWater HUB fits your home?
How much of the house should stay on?
Essential protection
The systems you cannot live without: network, lighting and home control, security, refrigeration and anything with a processor that would be a real problem to lose.
Usually a HUB20
Enhanced protection
Everything in Essential, plus the other electronics in the house. A generator often covers the heavy loads during a long outage while the HUB keeps the sensitive ones clean.
Usually a HUB40, often with a generator
Whole Home protection
Every circuit in the house, for owners who do not want to repair or replace anything after a storm, especially built-in equipment.
Multiple HUBs or a 3-phase system, designed for the house
Who handles what on a project?
Plan
You build a Power Plan on this site. We review it, then visit the house to look at the service, the panels and the room where the system will live.
Design and specify
We work from your single-line diagram and panel schedules, register the project with RoseWater's engineering team, and specify the HUB, battery and any solar or generator tie-in.
Coordinate the electrician
A licensed electrician makes the connections at your panel. We work with yours or bring in one we trust, and we coordinate your solar installer or generator contractor if you have one.
Commission and program
RoseWater's technician delivers and commissions the HUB with us on site. We bring it onto your network and make sure your control, network and AV systems ride through a test outage.
Ongoing support
You get access to the HUB's built-in monitoring, and its alerts can come to us as well as you. Warranty claims and service go through us, so there is one number to call.
What do RoseWater owners and dealers say?
“While we do have power outages, we never know when it happens because our internet keeps running and our lights stay on.”

“Our service calls were reduced by 80%.”

Backup power questions
What is a RoseWater Energy HUB?
What is a RoseWater Energy HUB?
A RoseWater HUB is a whole-home power system that sits between the utility and your electrical panel. It conditions every circuit it serves, stores energy in a battery, and keeps the house running with zero transfer time when the grid fails. It also brings solar and a generator into one managed system.
How is a RoseWater HUB different from a generator?
How is a RoseWater HUB different from a generator?
A generator starts after the power goes out, so the house goes dark for about 10 to 30 seconds and every device reboots. A RoseWater HUB is always online, so there is no gap at all. It also cleans up the power you use every day, which a generator does not do. Many homes keep a generator too, and the HUB can use it to recharge during a long outage.
How is it different from a Tesla Powerwall?
How is it different from a Tesla Powerwall?
A Powerwall is a battery that switches the house over when the grid fails. A RoseWater HUB is a power conditioner first: every circuit it serves runs through it all the time, with surge protection, voltage regulation and noise filtering, and there is no switchover when the grid drops. It is built for large, technology-heavy homes where a flicker or a surge is expensive.
What does a RoseWater system cost?
What does a RoseWater system cost?
Every system is sized to the home, so we do not publish prices. Cost depends on your service size, which loads you back up, battery storage, and whether solar or a generator is involved. Start a Power Plan or book a consultation and we will give you a clear number for your house.
