Expert Engineering, Localized Energy Storage Compliance, and Industrial-Scale LFP Manufacturing for the Brazilian Renewable Market.
Brazil has emerged as one of the world's most dynamic markets for solar energy. With the enactment of Law 14.300 (the Legal Framework for Distributed Generation), the Brazilian energy landscape is shifting rapidly. While Net Metering remains a core driver, the increasing frequency of grid instability and rising peak-hour tariffs have pushed "Solar + Storage" from a luxury to a necessity for both residential and industrial sectors.
Protecting Brazilian businesses from power outages in regions with aging infrastructure.
Powering remote agricultural operations in Mato Grosso and Minas Gerais where the grid doesn't reach.
Reducing high electricity costs during the "Horário de Ponta" through smart battery discharge.
As a leading Solar Power Wall Battery Factory, Suntherra recognizes that Brazil requires hardware that can withstand tropical humidity and high ambient temperatures. Our technical roadmap focuses on Lithium Iron Phosphate (LiFePO4) chemistry, which is inherently safer and offers a longer cycle life (up to 6000 cycles) compared to traditional lead-acid or NMC batteries common in the South American market.

Choosing a battery partner is not just about price; it's about Information Gain and technical reliability. Our factory utilizes a vertically integrated manufacturing process, from cell sorting to final BMS (Battery Management System) calibration. For the Brazilian market, we have optimized our communication protocols to be 100% compatible with major inverter brands used locally, such as Deye, Growatt, Victron, and GoodWe.
We are currently transitioning toward Liquid Cooling Systems for commercial-scale batteries and All-in-One High Voltage (HV) systems for residential users. HV systems allow for higher efficiency in energy conversion and easier installation—a major trend we foresee for the Brazilian solar installer community in 2025.
Navigating the Inmetro certification process in Brazil is a significant barrier for many manufacturers. Suntherra works closely with local distributors to ensure all products meet the rigorous safety standards required for legal grid connection. Our batteries are also UN38.3, CE, and IEC certified, ensuring they can be transported safely to ports like Santos or Paranaguá without logistical delays.
Shenzhen Suntherra Battery Co., Ltd. is a professional manufacturer specializing in solar energy storage batteries and integrated power solutions for global renewable energy markets. Established in 2014 and located in Shenzhen, China, the company has developed into a reliable OEM and ODM supplier focusing on lithium batteries, deep cycle storage systems, and advanced solar energy storage technologies.
Suntherra operates a modern production facility covering approximately 12,000 square meters and employs more than 180 skilled staff members, including battery engineers, R&D specialists, and quality control inspectors. With advanced automated production lines, the company ensures high performance, safety, and long cycle life for every battery product.
Large-scale solar project developers in Brazil often require Customizable Solutions (OEM/ODM). Our factory supports these needs through:
Our commitment to E-E-A-T means we provide full transparency on cell grading (Grade A only) and cycle testing reports for every batch shipped to South America.
Yes, our BMS is pre-configured with CAN and RS485 protocols compatible with 95% of the inverters sold in the Brazilian market, including Deye, Growatt, GoodWe, and Victron.
Our wall-mounted units feature IP55 and IP65-rated enclosures and conformal coating on the internal PCB/BMS to prevent corrosion from saline humidity in coastal cities like Recife or Salvador.
Production typically takes 15-20 days. Sea freight to Santos or Paranaguá usually takes 35-45 days. We provide all necessary documentation (Packing List, CI, CO, MSDS) to ensure smooth customs clearance.
We provide all technical datasheets and international test reports (IEC 62619, UN38.3) required by local laboratories in Brazil to facilitate the Inmetro certification process for our partners.
