What to write
We want to help you out.

- What happens when the power goes out: medical equipment, kupuna or keiki at home, spoiled food, lost work, a business that has to close
- How backup power would change things for you
You don't need to be a good writer, and spelling doesn't count. Likes, shares, and followers don't count either.

When the grid goes down, your house stays on.
During this year's storms, Hawaiian Electric reported hundreds of thousands of customers without power. The families with whole-home backup finished cooking dinner. The E10 takes over in less than 20 milliseconds when the grid drops, fast enough that your clocks don't reset and your fridge never notices.
The features, in plain terms.
Under 20ms switchover
A human blink takes about 100 milliseconds. When the grid drops, the E10 takes over in under 20. Clocks do not reset, wifi does not drop, the freezer never knows.
Storm Guard mode
Give it your address and it watches National Weather Service alerts. When a warning goes up, it charges the batteries to full automatically, so the storm arrives to a full bank.
Central A/C start
Anker rates the surge to start a 5-ton central A/C with enough battery packs attached. Two units can start a 5-ton and a 3-ton at the same time.
Manual off-grid
One toggle in the app cuts the grid and runs the house on stored and solar power alone.

Built like island infrastructure.

Four parts, one job: keep the house on.
The brainE10 Power Module
The inverter and controller. It watches the grid, converts battery and solar power into house power, and makes the under-20ms switchover decision so you never notice the outage.
The tankB6000 Battery Module
A 6.1kWh LFP battery pack with EV-class cells and a 10-year design life. Stack up to five per unit, and add more later without replacing anything.
The handshakeSmart Inlet Box or Power Dock
The connection to your home's panel, installed once by an electrician. The Power Dock also lets systems grow to multiple E10 units for larger homes.
The insurance policySmart Generator 5500
For the worst-case week with no sun, this tri-fuel DC generator tops the batteries automatically in short off-peak sprints. Most homes never need it; it's there for the ones that do.
How it goes in.
See it running
Come to the Kalihi showroom, watch the live system carry real loads, and ask us anything. No appointment needed.
We size it to your home
We look at your panel, your bills, and what you refuse to lose in an outage, then quote the system as a complete project. Honestly, including when a smaller setup is all you need.
Delivery and setup, handled
The E10 isn't a box you carry out. Your quote covers getting it to your home and set up properly.
The next outage is boring
The grid drops, the E10 takes over, and dinner keeps cooking. That's the whole point.
The E10 makes sense if...
- Someone in the house relies on powered medical equipment
- You work from home and an outage means lost income
- You're done throwing out a freezer full of food after every storm
- You have rooftop solar, or want it, and want it working when the grid isn't
If you just need the fridge and phones covered, a portable solar generator does that for a fraction of the price, and we'll tell you so. See the portable lineup →
Start small or go whole-home. It's the same system.
Every configuration below uses the same power module and batteries, so nothing you buy today gets replaced later. You add to it.
The Dolly Setup
6.1kWhPower module plus one battery on the dolly. Rolls where you need it, plugs into an inlet, backs up the essentials.
First step into backupEssential Home
12 to 18kWhModule plus two or three batteries and the inlet box. Fridge, freezer, fans, lights, and devices for about two days on battery alone.
Most Oʻahu householdsWhole-Home + Solar
24 to 30kWhFour or five batteries plus solar panels. Runs the house, cycles the A/C in bursts, and refills itself every morning.
Ride out anythingMulti-Unit
Up to 90kWhTwo or three E10 units on a Power Dock for large homes, ohana units, or small businesses that can't go dark.
Maximum resilienceEvery configuration is quoted as a complete project. Play with the calculator below, then come see the system running and we'll build the quote around your panel and your plans.
Your batteries. Your appliances. Your runtime.
Each B6000 battery pack holds about 6.1kWh, and one E10 takes up to five. Pick your battery count, tap what you'd run in an outage, and watch the runtime move.

What are you running?
Typical household draws; your appliances will vary. Bring your real list to the store and we'll run your exact numbers.
Add solar panels and the sun refills the bank every morning, stretching this through a long outage.
Size it in storeEstimates only: figures use nominal battery capacity and typical appliance draws. Real-world runtimes are usually 10 to 15% lower after inverter losses, and your appliances vary. Call (808) 833-3797 for exact sizing.
