A complete off-grid wind-solar hybrid power station has been officially deployed along Vietnam’s rural expressway, delivering stable, uninterrupted power for roadside traffic surveillance cameras. Faced with the limitations of traditional mains power laying in vast paddy field areas—high construction cost, long-distance wiring failure risk and unstable grid supply—the local traffic authority adopted a customized 2000W PV + 800W horizontal wind turbine hybrid energy system to build an independent, self-sustaining power supply for all highway monitoring equipment.

System Configuration & Core Components

This all-in-one renewable energy solution integrates three core devices from JC Solar, ensuring efficient energy collection, conversion and storage under Vietnam’s tropical monsoon climate:

1. Dual MPPT Wind Solar Hybrid Controller Model sourced from dual-mppt-wind-solar-hybrid-controller Equipped with independent dual MPPT tracking channels for solar panels and wind turbine separately, the unit maximizes power harvesting efficiency both in sunny daytime and breezy cloudy/rainy days. It supports automatic overcharge, over-discharge, lightning surge and short-circuit protection, perfectly adapting to Vietnam’s frequent thunderstorm weather beside rice fields and mountainous highways. Real-time working data including voltage, current and battery state can be displayed on its LCD screen for easy on-site inspection.

2. JN-H500W Pure Sine Wave Off-Grid Inverter Standard power conversion module: off-grid-500w-power-inverter The pure sine wave output eliminates current distortion, protecting precision monitoring cameras, network transmitters and auxiliary sensing devices from damage caused by unstable modified sine wave power. It converts stored DC battery power into stable AC power matching Vietnam’s local 220V/60Hz standard, meeting the continuous operation demand of 24/7 highway video surveillance.

3. Horizontal Axis Wind Turbine 800W wind generator unit: horizontal-wind-turbine Installed on the top of the monitoring tower, the low-start-speed horizontal wind turbine captures valley and crosswind along the expressway. It complements the 2000W solar panel array: solar modules generate abundant power during strong daylight hours, while the wind turbine supplements electricity output on cloudy, rainy and dawn/dusk periods when sunlight is insufficient.

The full system layout consists of two groups of high-efficiency monocrystalline solar panels mounted on the metal monitoring tower, one 800W horizontal wind turbine fixed at the tower apex, a waterproof insulated power cabinet pre-installed with the hybrid controller, pure sine wave inverter and deep-cycle energy storage batteries. The whole set is designed with full IP65 outdoor waterproof, dustproof and anti-corrosion treatment to resist high humidity, heavy rain and intense UV radiation in Vietnam’s agricultural plain environment.

Project Advantages for Vietnam Highway Monitoring

1. 24/7 Uninterrupted Off-Grid Power Supply The wind-solar complementary design solves the single solar system’s power shortage problem on cloudy days and rainy seasons. Combined battery energy storage ensures surveillance cameras run non-stop day and night without relying on municipal power grids.

2. Massive Cost Reduction for Road Infrastructure Eliminates expensive long-distance cable trenching, transformer setup and routine grid maintenance work along remote rural highways surrounded by rice paddies and scattered residential buildings. No recurring electricity bills, achieving zero operational energy cost after one-time installation.

3. Strong Adaptability to Local Vietnamese Climate Dual MPPT controller boosts solar power generation under strong tropical sunlight; low wind startup turbine works steadily with valley wind between mountain ranges; fully sealed power cabinet prevents moisture damage from rice field water vapor and seasonal heavy rainfall.

4. Low Maintenance & Long Service Life All core JC Solar components feature robust industrial-grade structure with multi-layer anti-rust coating for tower and bracket parts. The intelligent controller automatically regulates energy flow, reducing manual inspection frequency for highway management teams.

5. Eco-Friendly Zero-Carbon Solution Fully relies on renewable solar and wind resources, cutting carbon emissions for traffic monitoring facilities, matching Vietnam’s national renewable energy development targets for transportation infrastructure.

Application Scenario Expansion

This JC Solar wind-solar hybrid off-grid power system is not limited to Vietnam’s highway surveillance cameras. It is also widely applicable for rural traffic monitoring, border defense camera stations, agricultural field environmental monitoring, mountain fire warning equipment, remote village signal base stations and other off-grid remote equipment power demands across Southeast Asian tropical regions.

Conclusion

The successful operation of the 2000W solar + 800W wind hybrid power station on Vietnam’s expressway proves that integrated dual MPPT wind-solar solutions are the most reliable, cost-effective off-grid power choice for roadside monitoring projects in remote agricultural and mountainous areas. As Southeast Asian countries accelerate transportation infrastructure construction, standalone wind solar hybrid systems will become the mainstream power solution for remote surveillance, marking a new green energy trend in global intelligent transportation.
