Data from the EPE (Energy Research Company) indicate that at the end of 2020 Brazil had more than 200 locations not connected to the SIN (National Interconnected System). For those regions where access to electricity is precarious or non-existent, an off-grid system is a great solution.

This type of solution has been applied in several places such as farms, islands, industries, businesses, telecommunication towers and homes. This market opening has attracted several battery brands to the country, including Dyness .

The company focuses on researching and manufacturing lithium iron phosphate battery energy storage solution. It currently has two production factories in China, located in the two cities of Yangzhou and Taizhou, both in the eastern province of Jiangsu.

In addition, Dyness has two R&D (research and development) centers located in Xi'an City, Shanxi Province, and Yangzhou City, Jiangsu Province. Xi'an R&D center mainly focuses on research and development of battery materials.

While the Yangzhou center focuses on battery device R&D. The production factories are in China. With strong R&D and production capabilities, Dyness' energy solutions have served over 50,000 projects in Europe, Oceania, Africa, Asia and Latin America.

Off-grid system in an indigenous community

In Brazil, several off-grid projects were installed using Dyness' solution through a partnership with distributor Aldo . One of these projects was a 7,035 kWp off-grid photovoltaic system to supply the UBS (Basic Health Unit) of the Avá-Canoeiro indigenous village , in the region of Minaçu (GO).

The installation of the solar plant was made possible by TAESA (Transmissora Aliança de Energia Elétrica SA) through environmental compensation and supervised by Funai (Fundação Nacional do Índio).

The plant was installed by the electrical engineering company Fonte Solar in the carport model, which works as a secure parking lot for the Funai pick-up. In total, there are 24 335 Wp photovoltaic modules, a 100A charge controller, two 5 KVA Growatt inverters and two 14.4 kWh Dyness batteries. The total investment was R$ 95 thousand.

“The whole project was a big challenge. Not only to take the equipment to a remote area, but also to convince the entire tribe that that equipment would bring concrete benefits to the village”, says Natália Maestá, electrical engineer and CEO of Fonte Solar.

“It was extremely gratifying to work on this project, taking clean and sustainable energy, in addition to contributing to the health and perpetuation of such a warrior people”, added Natália.

The photovoltaic system must guarantee energy for the service of the UBS in the indigenous village, being able to keep medicines and vaccines refrigerated. Also according to the engineer, the system is managed remotely, which allows the operation of the health post and health care for the Indians 24 hours a day.
