Off-grid with peace of mind, self-sufficient green energy: Naton Energy’s 261kWh energy storage system powers a Romanian farm

Abstract

At a modern farm on the outskirts of Bucharest, the capital of Romania, an energy self-sufficiency revolution has been successfully achieved. Faced with the challenge of an off-grid location, Renac Power Energy deployed a 125kW/261kWh fully off-grid energy storage system. Centred around the ESS-261 commercial and industrial integrated energy storage cabinet and a 125kW PVS solar controller, the system has achieved energy self-sufficiency. Not only does it ensure the farm’s stable operation 24/7 throughout the year, but it also saves over 120,000 yuan in annual electricity costs, establishing itself as yet another successful model for off-grid applications in Europe.

Weak Power Supply: How Can Agriculture Thrive?

For commercial and industrial users in remote areas or regions with weak grid infrastructure, ‘difficulty in accessing electricity’ is a key bottleneck constraining development. This large-scale farm in Romania faced precisely this dilemma:

Absence of the grid: Located in a rural area, the public grid supply was unstable.

Reliance on diesel generators: Backup power from diesel generators is costly, noisy and requires complex maintenance.

Operational constraints: Unstable power supply limits the farm’s operations.

All-in-One: Building the Heart of Green Energy

To address the farm’s specific needs, Renac Power Energy provided a DC-coupled off-grid solution centred on the ESS-261 Commercial and Industrial Energy Storage Cabinet:

Core Configuration: ESS-261 Commercial and Industrial Energy Storage Cabinet: 125kW/261kWh × 1

PVS Solar Controller: 125kW × 1

System Highlights: DC-coupled: Efficient integration with rooftop PV (DC) systems to maximise the utilisation of renewable energy. Intelligent Energy Management: The system automatically allocates energy flows between PV, storage and backup diesel generators (if available), ensuring stable load operation around the clock.

Cutting-edge technology, setting the benchmark for off-grid systems

The ESS-261 Commercial and Industrial Energy Storage Cabinet used in this project integrates multiple industry-leading technologies to ensure long-term, reliable operation in harsh environments:

Demonstrating value, a win-win for economy and sustainability

Shaping the Future, Pioneering a New Chapter

From China to Europe, Renac Power Energy remains committed to addressing the energy challenges faced by users worldwide through leading-edge energy storage technology. The success of the Romanian farm project not only validates the exceptional performance and cost-effectiveness of the Renac Power ESS-261 in purely off-grid scenarios, but also provides a replicable model for energy self-sufficiency in off-grid regions, islands and remote commercial and industrial facilities across the globe.

Moving forward, Renac Power Energy will continue to be driven by technological innovation, bringing green, stable and smart energy to every corner of the world. Wherever green energy reaches, our mission is fulfilled. On the journey towards energy freedom, we walk alongside you.
