Vietnam’s Rang Dong Installs Off-grid Solar System in Da Nang
The Hanoi-based firm, fully known as Rang Dong Light Source and Vacuum Flask Joint Stock Company, has completed installing a specialized 2kWp off-grid solar system for a high-productivity livestock farm in Da Nang’s Son Tra peninsula. The project highlights Rang Dong’s capability to provide flexible and robust energy solutions in challenging geographical locations where access to the national electricity grid is either unstable or unavailable.
Technical overview
The off-grid solar system is engineered to function as a completely self-sustaining energy hub. Unlike grid-tied systems, this setup operates independently, utilizing high-performance battery storage to ensure continuous power supply regardless of the national utility status.
The system architecture includes specialized solar modules optimized for the high-salinity and coastal humidity of Da Nang. These panels are paired with an intelligent controller and a high-capacity storage unit that manages the energy flow, prioritizing essential farm operations such as lighting, ventilation and automated feeding systems.
This technical precision guarantees that the farm remains operational 24/7, safeguarding the health of the livestock and the efficiency of daily routines.
Practical benefits
The adoption of an Off-grid Solar System offers a comprehensive solution for agricultural investors and residents in remote terrains. The system is built upon four core advantages:
Energy autonomy: Users gain complete control over their power source. By not relying on the national grid, the farm is immune to power outages, grid maintenance schedules or fluctuating electricity tariffs.
Operational flexibility: The system is designed for easy installation and mobility. Its modular nature allows it to be deployed across diverse terrains, from mountains to islands, making it an ideal choice for nomadic or expanding agricultural models.
System stability: The integrated inverter technology ensures a consistent and stable voltage output. This protection is crucial for sensitive farm equipment and electronic devices, preventing damage caused by sudden surges or voltage drops.
Customizable design: Rang Dong offers bespoke configurations tailored to the specific energy demands of each client. Whether for a small-scale farm or a larger facility, the system can be scaled to meet varying consumption profiles.
Strategic impact
The successful deployment in Da Nang serves as a model for sustainable rural development. By providing a reliable Off-grid Solar System, Rang Dong enables local businesses to modernize their production processes without the high costs of extending grid infrastructure to remote areas.
This initiative aligns with the national goal of agricultural digitalization and green energy transition. Rang Dong’s role as a comprehensive solution provider—from manufacturing to technical consultation and maintenance—reaffirms its position as a leading technology partner in Vietnam.
By bridging the energy gap with “Green and Smart” solutions, the company contributes to a more resilient, self-reliant, and environmentally friendly economy. It demonstrates Rang Dong’s commitment to bringing “Make in Vietnam” green energy to every corner of the country, from urban centers to remote agricultural zones.
