Bankable Offshore & Onshore WRA Power Solutions
Engineered in Britain for global wind energy developers. Hybrid wind, solar, and methanol fuel cell systems specifically designed to eliminate power-loss data gaps in remote wind measurement campaigns.
The Engineering Challenge
Wind Resource Assessment (WRA) requires uninterrupted 12-to-24-month continuous measurement datasets. A single power drop out during high-wind winter events ruins bankability, delays financial close, and increases Levelised Cost of Energy (LCOE).
Modern remote sensing devices—including pulsed LiDAR units (such as Vaisala WindCube or ZX Lidars 300) and continuous wave sensors—draw a constant baseline power of 45 W to 150 W. Crucially, internal window heaters and optical de-icing modules can surge continuous consumption to over 250 W during freezing weather.
Standard off-grid solar systems inevitably suffer from winter solar deficits. In high-latitude installations (above 50°N/S), solar irradiance drops by up to 85% between November and February. Relying on oversized battery banks alone leads to deep-cycle degradation, premature battery failure, and costly emergency helicopter or field maintenance visits.
Our autonomous LiDAR power systems solve the winter solar drought by pairing hyper-efficient horizontal or vertical axis micro wind turbines with high-output monocrystalline solar modules, industrial AGM/LiFePO4 energy storage, and automatic Direct Methanol Fuel Cells (DMFC).

Architecture & Components
Every component inside our LiDAR wind measurement power systems is chosen for low internal power consumption, high thermal stability, and maximum survival in harsh environments.
Our LE-v150 and LE-300 turbines feature heavy-duty permanent magnet alternators and low cut-in speeds (2.6 m/s), generating power when solar input is zero. Tested to survive sustained winds exceeding 27 m/s (60 mph).
Direct Methanol Fuel Cells act as an intelligent back-up generator. When battery voltage drops below a set threshold, the DMFC kicks in automatically, consuming minimal fuel to recharge batteries regardless of weather.
Real-time system health dashboard powered by Victron Cerbo GX. Remote engineers can monitor battery state of charge, solar/wind generation, temperature, load current, and methanol fuel levels over 4G/5G or Satellite IoT.
Fully sealed powder-coated aluminum or 316-grade stainless steel enclosures equipped with internal heating elements, prevent ice build-up, salt corrosion, and moisture damage to critical charge controllers.
Industry Foresight
As wind energy projects move into deeper offshore waters and complex mountainous terrains, procurement specifications for remote measurement power are undergoing four major paradigm shifts.
Global developers (such as Ørsted, RWE, and Equinor) are moving away from single-source power systems. Procurement tenders now explicitly require quad-source redundancy (Solar + Wind + Battery + DMFC) to satisfy insurance and project bankability underwriters. Systems without micro-wind or automated fuel cells are increasingly flagged as high-risk assets.
Future power systems are no longer passive battery boxes; they are intelligent IoT nodes. Modern RFPs require edge-computing controllers capable of predictive algorithms—forecasting low-irradiance stretches using ERA5 meteorological models and dynamically throttling non-critical auxiliary loads before battery depletion occurs.
Time-to-first-measurement is critical. Onshore procurement managers demand mobile off-grid power trailers and fold-out solar skids that can be transported via light commercial vehicles or helicopters and fully deployed by a crew of two in under 45 minutes without requiring heavy cranes.
Zero-emission requirements are replacing noisy, high-maintenance diesel generators. The shift toward Direct Methanol Fuel Cells reduces fuel transportation frequency by up to 90%, virtually eliminating carbon emissions, noise pollution, and risk of diesel ground contamination on protected ecology sites.
Why Leading Edge Power
Since 2009, Leading Edge Power has engineered and manufactured industrial off-grid power solutions at our dedicated facility in Pontrilas, Herefordshire, UK. We are not just system integrators; we design and manufacture our own micro wind turbines, control panels, and custom power skids in-house.
Our engineering team uses high-resolution ERA5 reanalysis datasets blended with the Global Wind Atlas to perform microclimate energy modelling for your exact GPS coordinates. This ensures that every system delivered is sized honestly for the worst-case month of the year, preventing mid-winter blackouts.
Our technicians hold Global Wind Organisation (GWO) certification, giving us the offshore technical capability to support offshore wind developers in the North Sea, North America, and Asia-Pacific.

Our off-grid hybrid power systems keep critical measurement and telecom infrastructure operational in the most demanding environments on Earth.
Procurement & Technical FAQ
System sizing begins with a detailed energy profile analysis. We model your specific LiDAR device continuous wattage (e.g., 50W baseline plus window heating peak loads) against historical satellite weather data (ERA5 reanalysis) for your exact deployment site coordinates. Rather than sizing based on annual averages, we engineer for the worst winter month (typically December/January in the Northern Hemisphere), incorporating safety headroom of 30% and adding back-up energy generation (such as EFOY Direct Methanol Fuel Cells) to bridge extreme solar droughts.
While solar PV performs well during spring and summer, winter months present low sun angles, shorter daylight hours, and heavy snow cover on panels. Fortuitously, winter coincides with the highest average wind speeds in most coastal, mountainous, and offshore regions. Integrating a rugged small wind turbine (like the LE-v150 or LE-300) delivers nighttime and winter energy generation, maintaining battery state-of-charge when solar power drops to near zero.
The Direct Methanol Fuel Cell acts as an automated DC generator integrated directly into the hybrid system's charge controller setup. When battery voltage drops below a pre-configured low threshold (e.g., 23.5V on a 24V DC bus due to prolonged cloud and calm weather), the fuel cell starts automatically, producing clean DC power from liquid methanol. Once batteries reach full charge (or solar/wind generation resumes), the fuel cell returns to standby mode. A 28-litre methanol cartridge typically provides over 31 kWh of backup electricity—enough to run a typical LiDAR unit continuously for weeks without human intervention.
Every system includes an industrial telemetry gateway (Victron Cerbo GX or custom MODBUS router) connected via global 4G/5G multi-network SIMs or satellite communications (Iridium/Starlink). Engineers can monitor real-time battery voltage, state of charge, solar panel yield, wind turbine RPM/wattage, ambient temperature, fuel cell status, and remaining methanol fuel volume through a cloud dashboard. Automatic email/SMS alerts trigger prior to any critical low-voltage event.
Yes. Our offshore-variant power pods are built with 316-grade stainless steel hardware, marine-grade anodized aluminum, and IP67 sealed junction boxes to resist aggressive salt-spray corrosion. Our LE-v150 storm turbines use sealed ceramic-hybrid bearings and neodymium magnets designed for severe offshore environments. Furthermore, our installation engineers are GWO (Global Wind Organisation) certified for safe offshore deployment and service.
While Lithium Iron Phosphate (LiFePO4) offers high energy density, standard lithium batteries cannot be safely charged at temperatures below 0°C without internal heating systems. For sub-zero mountain or polar deployments, we recommend our specialized Deep-Cycle AGM or heated Lithium systems. Sealed AGM batteries remain operational down to -30°C without freezing, providing robust, un-heated winter reliability for remote sensor stations.
Our hybrid systems are designed for 12-to-24-month unattended service intervals. Primary routine maintenance involves inspecting electrical torque settings, wiping solar panel surfaces during planned site visits, and replacing methanol fuel cartridges if the fuel cell was engaged during winter. Wind turbines utilize brushless direct-drive alternators with no gearboxes, minimizing mechanical wear.
