Settled — the whole panel
The system backs your main service panel, not a critical-loads subpanel. No one asks you to nominate circuits, nothing gets left off, and there is no moment during an outage where you find out the wrong outlet was chosen.
Battery backup
It backs the whole house. The question is for how long.
There is no must-run circuit list to argue over. A Duracell system sits behind your main service panel and carries the whole thing, so the only real variable is time — and time is what the arithmetic on this page is about.
Scope and duration
The variable — how long
Kilowatt-hours of stored energy set how long the house runs before the battery is empty. Read the usable figure, not the nameplate — you never get 100% of it, and the difference is the first thing an honest spec sheet tells you.
Kitchen-table arithmetic
What your house actually draws.
This is not a list to choose from — everything here is covered. It is how you reason about duration. A house idling on the fridge, the internet and some lights lasts a long time. The same house running central A/C through an August afternoon empties the same battery in hours. Same scope, very different clock.
| Load | Rough draw | Notes |
|---|---|---|
| Refrigerator | 100–200 W | Average, running |
| Chest freezer | 50–100 W | Average, running |
| Internet + router | 20–40 W | Continuous |
| LED lighting, a few rooms | 60–150 W | Continuous |
| Well pump | 700–1,500 W | While running; more at startup |
| Mini-split, one room | 500–1,200 W | Varies with outdoor temp |
| Central A/C | 2,500–5,000 W | Much more at compressor start |
Ranges, not promises. Your appliances are your appliances — we read your actual usage off the bill and the panel rather than working from a table.
Battery or generator
We will tell you when it is a generator.
Both back the whole house. The split is duration and upkeep: if your worst case is four days of uninterrupted power, a generator is the honest answer and we would rather say so than sell you a system that disappoints in year one.
| Home battery | Standby generator | |
|---|---|---|
| Transfer time | Fast enough that most people see a flicker. | Several seconds to sense, start and transfer. |
| What it backs | The whole main panel. Nothing is left off a list. | The whole main panel, if it is sized for it. |
| Runtime ceiling | Until the stored energy is gone. Finite. | As long as the fuel lasts. Effectively days. |
| Maintenance | Firmware and a warranty to read carefully. | Oil, filters, exercise cycles, service visits. |
| Noise and exhaust | Silent. Nothing to vent. | Audible; combustion siting rules apply. |
| Use on ordinary days | Participates in your electricity plan year-round. | Sits idle until the grid fails. |
What we install
Duracell home energy storage.
It backs your whole main panel — that part is not a decision you have to make. What we size is duration, against your real usage, and we show you the usable capacity figure before you decide anything.
- Permitted, inspected, and to code.
- Whole main panel backed. No circuit list, no exclusions.
- Warranty terms explained in plain language before signing.
- The person who reads your usage plans the install.
Duracell home energy storage, owned by Solrite and leased to you. It backs the main service panel — the whole house — so there is no circuit selection to negotiate. We show you the usable capacity figure honestly, because that is what sets how long the house runs.
Yes. The Duracell system backs the main service panel entirely — the whole house, not a critical-loads subpanel. There is no list of circuits to choose between and nothing gets left off. What is finite is time, not scope: a battery holds a set amount of energy, so the real question on the call is how long it carries your house, and that depends on what you are running while the grid is down.
Both cover the whole house here, so the difference is duration and upkeep. A standby generator runs as long as the gas keeps flowing, which wins if your worst case is several days without power. A battery holds a finite amount of energy — but it is already on when the grid drops, with no fuel, no engine, no noise and no service schedule, and it works for you on ordinary days too. Most of the houses we talk to are the second case.
