With a strong international presence and recognized as one of the references in safety for photovoltaic systems, Projoy Electric highlighted that it is ready to expand its presence in Brazil, bringing to the national market its expertise in rapid shutdown and a complete line of protection solutions.
The company, which has a significant presence in Europe and Asia, is investing in its own technology and local technical support to gain ground among Brazilian integrators and distributors.
According to the company, the goal for 2025 is to consolidate its operations in the country, aligning innovation, safety and accessibility to meet the growing demands of the solar sector.
Global history and broad compatibility
According to Marcelo Aurélio dos Santos, Sales Director in Brazil at Projoy Electric, even before the company was officially in Brazil, the products were already arriving in the country through string inverter manufacturers, who used disconnecting switches.
“In 2019, we started supplying disconnect switches to the main domestic string box manufacturers. Currently, Projoy holds 80% of the Chinese domestic market for disconnect switches, used by the main global brands of string inverters, and 85% of the market for DC circuit breakers for energy storage systems,” he said.
The next step, according to him, is to consolidate the company's global flagship in Brazil: rapid shutdown, the manufacturer's solution that is fully compatible with ABNT NBR 17193: 2025. “Abroad, this is our best-selling product. In Europe, Asia and the United States, rapid shutdown is already a consolidated piece of equipment.”
“What sets us apart in Brazil is that we are bringing a mature product, optimized over the years and tested in different markets,” he highlighted.
Glenda Chuva, Business Development Manager at Projoy Electric, reinforces: “Our international experience, with more than 110 GW installed in rapid shutdown solutions, gives us a very solid base”.
“This number represents more than double the total photovoltaic capacity installed in Brazil. We are specialists in protection for solar systems and this is reflected in what we offer,” he stressed.
In addition to technical performance, executives highlight universal compatibility as a major differentiator. “While many competitors face compatibility issues with various brands of string inverters, our technology is fully compatible, immune to EMI (Electromagnetic Interference) noise and ensures flawless operation.”
“This universal compatibility also means that at the end of the inverter’s lifespan, replacement can be done without having to worry about compatibility, saving time and resources,” explained Elvis Cui, Projoy’s Sales Director for Asia Pacific/America/Middle East.
The company's Sales Director adds: “Our products are independent and transparent to systems such as AFCI and optimizers, ensuring efficiency and safety without interference.”
Complete portfolio and continuous innovation
Although the rapid shutdown device is at the heart of the strategy, Projoy Electric's portfolio goes beyond that. The company is also investing heavily in its line of power optimizers, which stand out for their efficiency, flexibility and integrated rapid shutdown.
“We are bringing state-of-the-art power optimizers to Brazil, with built-in rapid shutdown, ensuring maximum safety in emergencies or during maintenance,” said Glenda.
“Our optimizers maximize the energy production of each solar panel, with individualized maximum power point tracking (MPPT), optimizing system performance even in adverse conditions. In addition, we offer models with several power options and features, providing greater versatility and competitive cost,” he commented.
According to Marcelo, Projoy’s focus is always to deliver high-quality solutions at affordable and competitive costs to the domestic market – supported by a robust development team. “We have around 50 professionals dedicated exclusively to innovation, ensuring that our products meet the most demanding market demands.”
Expansion and investments in Brazil
To support this growth in the Brazilian market, Projoy is structuring a robust local operation. “We will offer direct technical support in Brazil, with a team prepared to serve both distributors and installers. We will not depend on the factory in China for this,” said the executive.
The investments are significant: the company is expanding its global facilities, with a new factory and offices totaling 33 thousand square meters and an initial investment of around R$ 200 million.
Globally, Projoy already serves around 80% of the string inverter manufacturers market in Asia and exports to more than 60 countries, including a presence in Latin America – with distributors in Colombia, Argentina, Chile and Mexico.
In Brazil, the expectation is clear: “2025 will be a year of consolidation for Projoy,” projected Glenda. “With the growing demand for rapid shutdown, driven by the ABNT NBR 17193:2025 standard, and our focus on promoting safety in photovoltaic systems, we will establish ourselves as a reference in the Brazilian market.”
“We believe that security is fundamental, and we are committed to providing solutions that guarantee the protection of people and assets, marking a new chapter for Projoy in Brazil,” he added.
Safety as a priority
For Projoy experts, a central point in the discussion about rapid shutdown in Brazil is raising awareness about the importance of safety in facilities. “The Brazilian market often seeks to reduce costs at any cost, but in this case it is essential to prioritize quality,” warned Marcelo.
“Rapid shutdown is not just another component, if poorly developed or installed, it can be the cause of serious problems, such as overheating and fires,” he pointed out.
Glenda emphasizes that Projoy is betting on a differential that goes beyond the product: the credibility built over the years. “We are not a company that copies solutions. Our DNA is in-house development and protection, especially for photovoltaic systems. This is our essence,” she concluded.
