Choosing a System Savant Power or RoseWater Energy?

Savant Power vs RoseWater Energy: what each system does, conditioned power and zero transfer time versus load management, budgets and which homes each one fits.

By Adam Zell of Boston Automations · Updated

The short answer

Choose RoseWater Energy when the house cannot tolerate any gap or any dirty power. Choose Savant Power when you want to see and control your circuits, manage loads to stay on the service you have, and add battery backup on a smaller budget.

RoseWater conditions every circuit it serves all the time with zero transfer time, and our RoseWater projects usually run $125,000 to $1,000,000. Savant puts modules in your existing panel and adds storage as needed. Savant Power Modules typically run $2,000 to $10,000, and Savant battery backup runs $10,000 to more than $100,000, depending on the size of the house and what you want backed up.

When is RoseWater the right choice?

RoseWater is for homes where any interruption is a problem: large AV and theater systems, network and security racks, home healthcare equipment, wine and spirits rooms, and owners who never want to see a flicker. A RoseWater HUB conditions the power for every circuit it serves, so surges, sags and noise are cleaned up before they reach the house, and when the grid fails the house does not notice. Read what a whole house UPS is for how that works.

When is Savant Power the right choice?

Savant Power is for homes that want control and visibility more than conditioning. Typical reasons: adding an EV charger or heat pumps without a bigger service, seeing which circuits use what, keeping essentials running from a battery in an outage, or managing loads on a standby generator. It works in the panel the house already has and can grow one module or one battery at a time. See how to avoid a service upgrade.

How do you decide?

Start with what has to keep running and how sensitive it is. If the answer is a few essentials and an EV, Savant is the fit. If it is a theater, a server rack and a house that should never blink, start with the Power Plan. If your budget sits below the RoseWater range, the Power Plan offers Savant Power or a standby generator instead, and we call to talk it through.

Frequently asked questions

What is the main difference between Savant Power and RoseWater Energy?

What is the main difference between Savant Power and RoseWater Energy?

RoseWater sits between the utility and the panel and conditions every circuit it serves all the time, so the house sees no gap when the grid fails. Savant Power manages and monitors circuits from modules in the panel, adds batteries for backup, and manages loads to stay within the service or the battery.

Which one costs more?

Which one costs more?

RoseWater projects usually fall between $125,000 and $1,000,000. Savant Power Modules typically run $2,000 to $10,000, and Savant battery backup runs $10,000 to more than $100,000, depending on the size of the house and what you want backed up.

Do both work with solar and a standby generator?

Do both work with solar and a standby generator?

Yes. A RoseWater HUB brings solar and a generator into one managed system, and its conditioning applies to generator power too. Savant Power Storage supports DC and AC coupled solar and hardwired standby generators with 2-wire start.

Which is better for a home theater or a large AV system?

Which is better for a home theater or a large AV system?

RoseWater, if the goal is clean, steady power with no flicker at all. That is what it is built for. Savant Power focuses on control, monitoring, load management and battery backup.
