Tigo Energy and Weco Certify MLPE–Inverter Compatibility, Advancing Flexibility and Efficiency in Residential Solar System Design
Tigo Energy, a global leader in intelligent solar and energy software solutions, announced today that the company has formally signed a certificate of compatibility with Weco S.r.l., a respected manufacturer of hybrid solar inverter technologies. This certification verifies the interoperability between Tigo’s Flex MLPE (Module-Level Power Electronics) product families—specifically the TS4-A and TS4-X lines—and a designated range of Weco’s single-phase and three-phase hybrid inverters when designed and installed according to recommended guidelines. By establishing this compatibility, the two companies aim to simplify the PV system design process for installers and engineers, while enabling end users to enjoy improved system performance, flexibility, and long-term value.
A New Milestone in Solar System Interoperability
At a time when the solar industry continues to accelerate toward modular, flexible architectures, the ability for various components to integrate seamlessly has become essential. The newly certified compatibility between Tigo Flex MLPE units and Weco hybrid inverters addresses one of the industry’s most persistent challenges: ensuring that different hardware platforms work harmoniously together, especially in installations where site constraints or performance expectations are high.
With this certification in place, solar professionals can confidently design systems that combine Weco’s robust inverter technology with Tigo’s advanced optimization, monitoring, and safety capabilities. The certification applies to select models within Weco’s growing portfolio of hybrid inverters, offering installers the assurance they need to select the ideal configuration for residential customers with varying energy goals. For homeowners, this integrated approach translates into more resilient solar energy systems with improved production consistency and a stronger return on investment.
Industry Leaders Reinforce Their Commitment to Solar Professionals
According to Federico Cusumano, R&D Manager at Weco S.r.l., the collaboration represents a meaningful step forward not only for the two companies involved, but for solar installers across Europe and beyond. “The compatibility between our inverter solutions and Tigo optimizers represents a significant step forward for the entire industry, and confirms our commitment to simplifying the work of solar professionals,” Cusumano stated. He emphasized that this certification grants designers and installers “greater sizing flexibility to optimize system configurations according to the precise requirements of each customer site.”
Cusumano’s comments highlight one of the most important advantages of MLPE-enabled hybrid systems: adaptability. Every residential project presents unique constraints, whether due to roof geometry, shading from nearby structures or trees, module orientation, or homeowner energy objectives. The compatibility between Tigo and Weco gives installers the tools they need to adapt to these challenges without sacrificing system quality or predictability. “Together, Weco and Tigo are delivering a more integrated, intelligent energy ecosystem focused on long-term value for the end customer,” he added.
Enhancing Performance Where It Matters Most
The use of Tigo MLPE with hybrid inverter architectures, such as those offered by Weco, creates meaningful performance and reliability benefits. Tigo’s MLPE technology is specifically engineered to address real-world challenges such as partial shading, module mismatch, or complex roof layouts—factors that are common in residential settings and can significantly impact energy yield if not managed properly.
By incorporating Tigo optimizers into Weco-powered systems, installers can achieve:
1. Improved Production Under Suboptimal Conditions
Even minimal shading on a module can affect the output of an entire string. Tigo’s optimizers mitigate this problem by allowing each module to operate at its maximum power point independently, preventing energy losses caused by slow-performing panels.
2. Greater Design Flexibility
Installers can mix module types, integrate varying tilt angles, or design around irregular roof shapes, knowing that Tigo’s MLPE will ensure consistent output. This flexibility is particularly valuable for homeowners with complex or constrained roof layouts.
3. Enhanced Monitoring and Module-Level Insight
With Tigo’s monitoring platform, installers and system owners gain real-time visibility at the module level, making it easier to diagnose issues, verify performance, and maintain long-term system reliability.
4. Increased System Safety
Tigo Flex MLPE units incorporate rapid shutdown capabilities that comply with global safety regulations. When paired with Weco inverters, these features help ensure safe installation, maintenance, and emergency response conditions.
Joint Webinar to Support Installer Education
Recognizing that education and training are central to accelerating the adoption of intelligent PV solutions, Tigo and Weco have also announced a joint webinar for solar installers and technical professionals. During this session, experts from both companies will present an in-depth overview of product portfolios, explore compatibility best practices, and share real-world case studies that demonstrate how the technologies complement each other in residential applications.
This educational initiative underscores a shared commitment to empowering solar professionals with the knowledge they need to deliver best-in-class systems. The webinar is scheduled for Thursday, February 5 at 4:30 p.m. CET, and installers are invited to register to secure their participation.
Building an Open, Future-Ready Solar Ecosystem
Gal Bauer, Senior Director of Validation, Growth, and Product Management at Tigo Energy, emphasized that the certification reflects Tigo’s continued focus on building an open, interoperable energy ecosystem. “For Tigo, this announcement is first and foremost about giving installers greater control at the module level without adding complexity to system design,” Bauer noted.
He explained that certified compatibility makes it easier for installers to deploy Tigo Flex MLPE exactly where it yields the most value—whether to overcome shading issues, enhance safety, or improve system monitoring—while preserving predictable system behavior and a streamlined commissioning process. Bauer also emphasized that this collaboration is part of Tigo’s broader effort to support partners across the industry with solutions that prioritize flexibility, safety, and long-term performance. “This is yet another concrete example of how Tigo continues to build an open ecosystem that prioritizes safety, flexibility, and long-term system performance.”
Resources for Installers and System Designers
A full list of Weco inverter models certified for compatibility with Tigo MLPE solutions is available through the Tigo MLPE Compatibility Page, where installers can verify supported configurations for upcoming residential projects. Additional information on the Tigo TS4 platform—including optimization, monitoring, and rapid shutdown products—can be found on the Tigo product page, which provides detailed datasheets, installation manuals, and system design guidance.
