HelioHelm turns location-aware solar forecasts into a practical energy plan built around your battery system, renewable generation, and the loads you rely on. Know what you can run, when to conserve, and when to charge—before your reserve gets tight.
Built for boats, remote cabins, vans, and other systems away from shore power or the utility grid, HelioHelm connects generation, storage, and demand in one forward-looking plan.
HelioHelm combines ECMWF weather data with photovoltaic modelling to estimate solar production hour by hour. Update your position as you move and plan around changing cloud, wind, and daylight conditions.
Turn your current charge, battery capacity, everyday demand, and expected generation into a 24-, 48-, or 72-hour state-of-charge outlook. Charging follows chemistry-specific limits and taper, while discharge reflects your bank’s capacity, voltage, and usable depth.
The Premium assistant reasons across your setup, forecast, and battery outlook to schedule optional loads, recommend when and how long to use auxiliary charging, and help review whether your configured hardware reflects your real system.
Start simple or describe the full setup. HelioHelm adapts the plan to your equipment, location, and day-to-day priorities.
Choose lithium, AGM, gel, or lead-acid. HelioHelm applies chemistry-specific charge efficiency, C-rate, voltage, and high-SoC taper, then models discharge from your configured capacity, system voltage, and usable depth-of-discharge.
Use one baseline estimate or list individual always-on and scheduled devices to reflect how your boat, cabin, or van really consumes power.
Find better times for watermaking, laundry, or a dive compressor. If reserve is at risk, the assistant can also recommend when and how long to run your generator or engine alternator, and help you review the setup behind the plan.
Compare expected generation with demand, spot likely surpluses or shortfalls, and explore the next few days without translating raw weather data yourself.
Spend less time calculating and more time confidently using the energy you have.
