How RevoluSun designed, donated, and installed an off-grid solar-and-battery system for a new community space, one that keeps the lights on, devices charged, and people connected, even when the grid goes down.

Aloha,

Some projects are about a single home. This one is about a whole community.

This past April, Sustainable Coastlines Hawaiʻi celebrated the grand opening of their new Solutions Center, a gathering space where anyone can stop in to charge their devices, cool off, talk story, and connect. It’s open to the community, and it runs entirely on the sun.

We’re proud to share that RevoluSun designed, donated, and installed the off-grid solar-and-battery system that powers it.

A community space that doesn’t depend on the grid

The idea behind the Solutions Center is simple and powerful: a place that’s always open and always powered, no matter what’s happening with HECO. On an ordinary day, it’s somewhere to charge a phone, get out of the heat, and gather. During an outage, whether it’s a passing Kona low or a multi-day storm event, it becomes something more: a spot where the community can stay charged and stay connected when the power’s out everywhere else.

For that to work, the Center couldn’t rely on the grid at all. It needed to make its own power and store it. That’s exactly what we built.

What we designed and installed

Our team handled the whole system end to end, from the engineering drawings to the final install:

• Rooftop solar. We mounted a solar array on top of the Center’s shipping-container structure, roughly 6.9 kW of panels generating clean power through the day.
• Stackable battery storage. That solar charges an EcoFlow Delta Pro Ultra system, a stackable battery-and-inverter setup that stores the day’s energy for use after dark. It’s modular by design, so capacity can grow as the Center’s needs do.
• A smart panel. The system ties into a smart electrical panel that keeps the Center’s essential loads “alive” during an outage, drawing seamlessly from stored power the moment it’s needed.
• Portable backup that can be swapped. The Center also runs two portable EcoFlow Delta units. One can charge while the other powers the space, and because they’re portable, they can be topped up from the grid when needed and moved wherever the power has to go.

The result is a system built for extended outages. The batteries don’t have to rely on sunshine alone; they can be charged from the grid ahead of a storm and run the Center’s smart-panel loads straight through a multi-day event.

The system, at a glance

• Solar: ~6.9 kW rooftop array on the container
• Storage: EcoFlow Delta Pro Ultra, stackable battery + inverter, expandable up to 30 kWh
• Backup control: dedicated smart panel for essential loads
• Portability: two swappable EcoFlow Delta units for flexible, grid-or-solar charging
• Designed for: extended, multi-day outages
