RESUN ENERGY CO,.LTD company cases

The project is located in a rural area of Bari, Italy. The main loads are heat pumps and new energy vehicles.  In order to reduce expensive electricity costs, the project adopts two RESUN R-5KSL series hybrid inverters and a 10kWh lithium battery energy storage system, combined with 8kw rooftop photovoltaics for residents, to jointly provide clean energy for users and reduce their living energy costs.

In the project in Pilsen, Czech Republic, four RESUN hybrid inverters were used in parallel, which is an interesting solution. It can mix and convert electricity from different sources to meet the power needs of home lighting, new energy vehicle charging, and water heaters. In addition, it can also realize intelligent power management and monitoring through the RESUN Little Sun EMS APP, thereby increasing power generation revenue.

Due to weak power infrastructure, farms in the suburbs cannot access reliable power sources. To generate electricity, they rely heavily on fossil fuels.   As fuel costs continue to rise, low-income farmers are even more unable to afford expensive energy expenditures.   For this reason, the local government installed a microgrid system for the farm. The PCS of the system uses a RESUN MPS hybrid inverter, which not only helps residents use the available local resources to generate electricity but also empowers them to manage and control this distributed new energy.

In order to ensure the daily electricity consumption of residents in the Alexandria community, the Johannesburg City Power and Gauteng Provincial Government jointly invested in constructing a 500kW/1MWh microgrid system to cope with the frequent power outage crisis. RESUN provided a 500kW MPS hybrid inverter for this project, combined with EMS to manage the charging and discharging of the microgrid system effectively.

Project Name: Off-Grid Power Supply System Upgrade for a Coastal Fishing Village in Namibia Namibia, located in southwestern Africa, has several small fishing villages along its long coastline. A certain fishing village, far from the national power grid, has long relied on diesel generators for electricity. This not only incurs high costs but also causes the noise and exhaust from the generators to have a certain impact on the coastal ecological environment. Meanwhile, the high salt spray, strong ultraviolet radiation, and occasional sandstorms in the coastal area place strict requirements on the weather resistance of power equipment. To improve this situation, the fishing village launched an off-grid power supply system upgrade project. After evaluating the local climate and power demand, it finally selected the 720W N-type Grade A solar cell dual-glass solar panel as the core power supply equipment. This solar panel uses N-type solar cells, which have higher conversion efficiency and a lower temperature coefficient. Under the strong sunlight conditions in Namibia, its power generation efficiency is about 8% higher than that of traditional P-type solar cells; Grade A solar cells ensure stable power generation and long service life. The dual-glass structure, with excellent salt spray resistance and water vapor permeability, can effectively resist high humidity and salt spray erosion in coastal areas. Moreover, its high surface hardness can withstand sandstorms. Before being put into use, the solar panel underwent targeted tests: In the neutral salt spray test simulating the salt spray environment of the Namibian coast, after 500 hours of continuous exposure, the surface of the module showed no corrosion or bubbles, and the power generation performance attenuation rate was less than 2%; In the high-temperature and high-humidity test (85℃, 85% humidity) for 1000 hours, the output power remained stable; In the sandstorm resistance test, simulating sandstorm impact at a wind speed of 70km/h, the glass surface had no scratches and the circuit connections were intact. At present, these 720W N-type Grade A solar cell dual-glass solar panels have completed deployment preparations and are about to be put into use in the fishing village. It is expected that after the system is completed, it can meet the basic electricity needs of 30 households in the village (lighting, small household appliances, charging of communication equipment, etc.), reducing diesel consumption by about 5 tons per year. This not only lowers the electricity cost for villagers but also provides a weather-resistant solution model for clean energy applications in coastal areas of Namibia.

As the demand for efficient and stable inverters in the European household energy market continues to rise, a batch of 5KW household single-phase low-voltage hybrid inverters is setting off for Europe in a full container.​ Designed specifically for household scenarios, this inverter is compatible with European household electricity standards with its single-phase low-voltage configuration. Its hybrid mode can flexibly integrate photovoltaic systems, power grids, and energy storage batteries, enabling intelligent energy distribution and efficient utilization. In daily household electricity use, it can efficiently convert photovoltaic power to meet the needs of lighting, home appliances, and other devices. Surplus electricity can also be stored in batteries, providing power support for nighttime or cloudy days and effectively reducing household electricity bills. ​ After rigorous factory testing and compliance certification, it meets all European electrical standards and environmental protection requirements in terms of voltage stability and safety protection performance. Now, the full container of inverters has been packed and reinforced, with each unit carrying the mission of providing reliable energy support for European households.​  This full-container shipment not only responds precisely to the needs of the European household energy market but also demonstrates confidence in the product's performance and quality. These 5KW household single-phase low-voltage hybrid inverters will arrive one after another in various parts of Europe, bringing smarter and more economical energy solutions to local families and helping European households move towards a greener and more efficient electricity lifestyle.

A family in Paris, France, often faced power outages due to aging local power grids, especially in winter storms. These outages disrupted daily life—interrupting heating, refrigeration, and charging of essential devices.​  Seeking a reliable solution, the family selected this 12KW inverter + 15KWH battery portable indoor unit.  Its compact size (1.2㎡) fits easily in home storage areas, and the low noise level (
