Off-Grid Power FAQ

GridVault systems range from $150,000 (GridVault 80) to $400,000+ (GridVault 320), depending on the scale of power you need. Every system runs on EcoFlow OCEAN Pro — the best components available, not a budget battery with a nice enclosure. This is infrastructure, built once and owned forever. Book a free consultation, and we'll help you find the right tier for your property.

It depends mostly on how far your site is from the nearest power line. Some utilities include a set length of line at no charge, and beyond that, extension costs rise with distance and can take months to over a year. Ask your utility for a written quote and compare it with a GridVault. We're happy to walk through that comparison on a consultation.

A quick way to size it is to look at the service at your main panel. A 200 amp service, for example, likely points to a GridVault 160. By the same logic, 100 amp points to the GridVault 80 and 400 amp to the GridVault 320. We'll confirm the right tier for your loads on a consultation.

No. GridVault systems are designed to operate fully independent of the utility grid — no connection required.

We don't have financing partners right now, but we're open to being flexible. Ask us on a consultation.

Your system is built and delivered in 4–6 weeks from signing — versus months to over a year for a new utility line extension. On-site installation takes approximately 3 hours.

We recommend a 12ft x 16ft concrete pad for your GridVault system.

Permits vary by county, so you'll work with your local jurisdiction directly. Your consultation team can help you understand what to ask about for your property.

Permitting depends on your local jurisdiction. GridVault is a portable building that your electrician connects to your home as its power source. We can help you navigate it, but you're ultimately responsible for the permits you pull.

Yes — GridVault is designed for undeveloped land as well as existing properties.

The same way you'd connect a camper or a home generator: plug in directly. For whole-home power, any licensed electrician can wire GridVault into your panel using the same process they'd use to connect utility power. Prefer we handle the integration? We can for an additional fee.

Yes, on both counts. GridVault delivers 24 to 96 kW of continuous power depending on tier — enough to run HVAC, pumps, and appliances simultaneously, all day, without flickering or shutdown.

And it's protected from every angle: every GridVault enclosure is climate-controlled with its own built-in air conditioning and heat, keeping conditions stable inside no matter the season. On top of that, EcoFlow OCEAN Pro itself is IP67-rated, flood-resistant up to 3.3 feet, and rated to keep operating from -4°F up to 140°F — so even in the harshest weather, there's no single point of failure.

On safety systems: every unit includes a built-in fire suppression module, an explosion-proof pressure release valve, and shock-resistant construction — protection built in, not bolted on.

It depends on how you heat. If your furnace runs on propane, GridVault only has to power the fan and controls, and with a backup generator you can keep the system charged for as long as you have fuel.

Every GridVault includes 2,400W of solar input that functions as a trickle charge for your batteries. Most of our customers charge their GridVault with a ground-mount solar array, available as an add-on; a generator works too. Each system can handle up to 80,000 watts of continuous solar input, so your charging capacity grows with you.

This is where GridVault's solar input capacity helps most. Depending on your loads, you may be fine if you install the maximum solar array the system accepts, and for longer cloudy spells a backup generator keeps you running.

The GridVault 320 is sized to handle EV charging. Talk to our consultation team about matching a system to your full load — HVAC, pumps, appliances, and vehicles.

Solar input capacity is built in from day one, with ground-mount solar available as an optional upgrade. Talk to our consultation team about upgrade paths between tiers as your needs grow.

Through an app on your phone, or you can add a wall-mounted monitoring station inside your home.

Every GridVault system is backed by EcoFlow's 15-year warranty, with the battery rated to retain at least 70% of its original capacity after 15 years.

Off-site commissioning, white-glove delivery, and first-year support are included with every system. Your EcoFlow Ocean Pro components also carry a 15-year manufacturer warranty.

Yes. White-glove support is included for the first year, so if you need anything, we handle it.

There is nothing like it on the market: this is the most power you can have built, delivered to your door, and backed by a 15-year warranty. We've done the integration work — and we're the first and only EcoFlow Ocean Pro Preferred Off-Grid Partner.
