Watch
See the window forming.
Identify material weather and low-solar conditions before they narrow the plan.
Independent power at sea
Your yacht’s power,
one step ahead.
Ungrid turns batteries, solar, shore power, generators, onboard loads, location, and weather into a clear energy plan—so you know what changed, what matters, and what to do next.
Built for Victron yachts first. Capabilities are being introduced in stages.

Freedom without constant vigilance
Leave the yacht.
Keep the operating picture.
Your power system keeps working while you are aboard, ashore, asleep, or hundreds of miles away. Ungrid is building a calmer way to understand what is happening, what is changing, and when your judgment matters.

Every source. One energy picture.
A yacht is more than
a battery percentage.
Batteries, solar, alternators, generators, shore power, onboard demand, connectivity, location, weather, and the next plan all shape the same question: how much energy margin do you really have?

One operating picture
Your equipment shows what the system is doing. Ungrid explains what it means for the next decision.
See tomorrow’s reserve
Know before reserve becomes risk.
Understand whether the yacht is rebuilding energy or quietly falling behind. See the strongest charging window, which loads can wait, and whether the yacht will be ready for the next departure, anchorage, or night aboard.

Storm Watch
When the weather changes,
your energy plan should change first.
A forecast tells you what the weather may do. Storm Watch connects that outlook to your yacht’s reserve, expected solar recovery, onboard demand, and remaining charging windows—so preparation starts while choices are still available.
Prepare
Build reserve early.
Use the strongest remaining charging window while choices are still available.
Protect
Hold the margin.
Move flexible loads and confirm the backup-power and communications plan.
Recover
Wait for confirmation.
Return loads when the weather and the next confirmed reading support it.

Storm Watch turns incoming weather into an energy plan.Energy guidance only. It does not replace official marine weather, navigation, onboard alarms, or seamanship.
One yacht. One operating picture.
Keep the right people on watch.
Give the owner a concise confidence view, crew the operating detail, and authorized service partners the signal they need—without turning every change into noise.

Calm by design
The sea creates uncertainty.
Your energy plan should reduce it.
Conditions change. Loads change. Plans change. Ungrid keeps rebuilding the energy picture around the yacht you have, where it is, and what comes next—so changing conditions become clearer decisions.
Your yacht. Your controls.
Guidance at sea.
Control aboard.
Ungrid is a trusted guide beside the operator, not an autonomous controller standing in for them.
Read-only by design
Ungrid reads and explains. Your onboard and vendor controls remain yours.
Operator authority
The owner or crew decides what changes, when it changes, and why.
Visible uncertainty
Stale, estimated, and unavailable information is never presented as confirmed fact.
Private location
Location is consented, purpose-limited, and treated as sensitive operating data.
Your yacht. Your energy plan.
Put your yacht’s power
one step ahead.
Start with Ungrid and help shape the intelligent energy watch for life at sea.
