Brazil, with its vast territory and growing energy demand, faces significant challenges in its grid infrastructure, which manifest themselves in problems such as power outages, poor grid quality, and sometimes even the risk of blackouts.
In this scenario, the photovoltaic energy market emerges not only as a clean and sustainable alternative, but also as a solution for the resilience of the national electricity system.
The decentralization of generation, inherent to solar technology, especially when considering systems with energy storage, offers a direct counterpoint to the traditional grid, enabling greater energy security and less dependence on an overloaded hydroelectric and transmission matrix.
In rural areas of Brazil, power outages and fluctuations also represent a bottleneck, and often a power outage can compromise some of the inputs produced, materials of utmost importance such as vaccines already purchased, for example, among others.
Furthermore, instability is particularly damaging to operations that rely on electric motors, for example, such as... irrigation systems and the refrigeration of products (milk, poultry) and sheds.
Inverters that support the operation of this type of machine are fundamental in the composition of photovoltaic systems with storage in rural areas.
In addition to all the challenges presented, there are uncertainties related to legislation and regulation, such as changes to energy compensation rules, for example.
Scheduled to take place in 2029, the change in the compensation scenario and consequently the new rule established could drastically reduce compensation for energy injected into the grid, making the most advantageous scenario for those who produce their own energy to generate and store it for use when needed, instead of injecting it into the grid and being compensated for the amount injected, as currently happens in most connected systems.
Considering all these challenges and the current scenario, the Sofa[Company Name], a manufacturer of solar energy and storage solutions, is bringing to market PowerEasy, a system that integrates hybrid inverters and low-voltage batteries aimed at residential and commercial applications.
According to the company, one of the main differentiators of the line is its flexibility to operate with the main electrical grid standards in the country (127V/220V, 120V/240V and 220V/380V), compatible with the voltages found in Brazilian homes and commercial establishments.
Regarding the product, it features 100% overload capability, which can be used when charging batteries and supplying AC loads simultaneously, and also has a current of 20A per input and compatibility with any module on the market, including 700Wp+ panels.
The PowerEasy line of inverters can power all of a customer's home appliances and equipment, regardless of the power grid or the equipment's voltage.
In 127/220V networks, the backup output can provide both 127V to power common everyday equipment such as routers, televisions, computers, lighting, etc., and 220V as well, enabling the supply of equipment such as air conditioners and gate motors, among others, bringing more comfort and convenience to the customer.
Customers served by 220/380V networks will also have all their single-phase equipment serviced normally, ensuring comfort and well-being during power outages.
According to the manufacturer, the target audience for the PowerEasy line includes both residential consumers seeking greater reliability and savings, as well as commercial and industrial consumers who wish to integrate solar systems to reduce their energy expenses.
released on Intersolar South America This year, the new product is already available through its partner distributors.
High efficiency and low losses
"With the PowerEasy solution, it is possible to generate energy for immediate consumption, export the surplus energy generated to the grid, or store this surplus in batteries, and the entire line is prepared to handle even more robust equipment, such as small electric motors or household appliances that have compressors, such as freezers, for example."
The entire line is capable of supporting twice the rated AC power for up to 10 seconds.
In application scenarios such as agriculture, for example, where the use of freezers and refrigerators for preserving important supplies is common, as well as the use of motors to operate gates or various systems, the inverter safely and stably handles this type of load, ensuring that daily operations in the field do not stop due to a power outage or grid instability,” the company said.
In addition to handling varying loads and operating at different voltage levels, one of the advantages is the ability to configure the inverter + battery system in the way that best benefits the customer.
A good example of this is the application of a system with an inverter and batteries to store energy and supply power during the day, supply power with the battery during times when there is no solar generation, and only as a last resort use energy from the grid.
This method, popularly called self-consumption, can be applied, for example, in scenarios where the grid compensation for the injected kWh is much lower than the value of the purchased kWh, optimizing the customer's entire self-generation and avoiding unnecessary losses with a compensation for injected energy that is much lower than the price of purchased energy.
This scenario could become a reality in Brazil by 2029 after the release of new energy compensation rules. Other challenges such as reverse flow, grid quality, power peaks exceeding grid capacity, etc., can also be solved or mitigated through the use of energy storage.
"In addition to the product, Sofar's exclusive platform will also allow for easy tracking of generation data and battery monitoring, making the product simple and intuitive to use," the company added.
Expectations and perspectives for the future
Expectations for the PowerEasy line are promising. Sofar believes that the growing demand for hybrid solutions in Brazil will allow the inverter to reach a large number of homes and commercial establishments.
"With a product tailored to the Brazilian market and features designed to meet customer needs, the expectation is that it will be possible to reach a large number of homes and businesses, further spreading the brand and the energy solutions we have available in Brazil," the company highlighted.
According to the company, the market is currently undergoing a transformation, and hybrid products are gaining traction. Several studies, such as... PDE 2035 released by EPE Storage systems are being pointed to as a solution to several challenges faced by the market today.
To keep up with market changes and participate in this new phase, Sofar has a strong presence in the inverter and hybrid systems market. The company has sought to stand out for the quality of its products and the specialized technical support offered to integrators, providing monthly technical training for its partners.
"Sofar has continuously invested in training professionals who work with its solutions through programs such as Safira, which takes place monthly and aims to professionalize integrators and partners in Sofar products and best market practices. These initiatives aim to strengthen the photovoltaic ecosystem, ensure the correct application of solutions, and expand the technical knowledge of professionals in the sector," the company concluded.
