Backup planning
We identify the circuits you want protected — kitchen, water, medical, office — and size storage to them.

Home battery & Powerwall storage on Maui.
Keep the essentials running when the grid goes down — and use more of the solar you already make.

Overview
Battery & Tesla Powerwall on Maui.
Outages are a fact of life on Maui. Battery storage turns your home into something steadier: lights, refrigeration, internet, and water pumps keep running, and your solar keeps working for you into the evening instead of being sent back to the grid.
Kaimana Energy designs battery systems — including Tesla Powerwall — around what actually matters to your household. We map your critical circuits, size the storage to match, and integrate it with your panel and solar so the switchover during an outage is seamless and automatic.
What a storage project includes
Powerwall & battery options
Tesla Powerwall and other quality batteries, matched to your home rather than a one-size default.
Solar integration
Storage is tied into new or existing solar so daytime production charges the battery, not just the grid.
Automatic transfer
Seamless islanding so protected circuits stay live through an outage without you flipping anything.
Smart panel coordination
Optional smart panel integration for circuit-level control and monitoring from your phone.
Monitoring & handoff
App monitoring configured and explained so you can see charge, usage, and backup status at a glance.
Why it matters.
The difference
01
Power through outages
Protected circuits stay on automatically when the grid drops — no generator to start.
02
Use your own solar
Store daytime production and draw on it at night instead of buying power back.
03
Quiet and maintenance-light
No fuel, no noise, no fumes — storage runs silently in the background.

Common questions
How many batteries do I need?
It depends on which circuits you want to back up and for how long. We start by mapping your critical loads, then size storage to keep those running comfortably. Some homes want to cover essentials for a day; others want whole-home backup. We design to your goal.
Can I add a battery to my existing solar?
In most cases, yes. We assess your current solar and panel setup and design a storage addition that integrates with it. If your system needs a small upgrade to support backup, we will tell you clearly before any work.
Does a battery work during a Maui outage?
Yes — that is the point. With battery storage and automatic transfer, your protected circuits keep running when Hawaiian Electric goes down, and your solar continues charging the battery during the day.
