Tigo Energy Unveils Powerful 725W, 22A Upgrade to TS4-A MLPE Product Line, Advancing Performance for Modern Solar Installations
Tigo Energy, Inc. (NASDAQ: TYGO), a global leader in intelligent solar and energy software solutions, has introduced a major enhancement to its industry-renowned TS4-A family of Module-Level Power Electronics (MLPE). With the release of its new 725W TS4-A model, the company delivers an MLPE solution purpose-built for today’s high-power, high-current solar modules, addressing the evolving demands of solar installers and project developers across the residential, commercial, and industrial (C&I) sectors.
As the solar industry continues to evolve rapidly—with photovoltaic module manufacturers pushing the limits of panel wattage and current ratings—Tigo has responded with innovation. The new TS4-A family member scales to meet these demands head-on, offering solar professionals and system owners the ability to extract even more energy from every square foot of rooftop space. The 725W TS4-A is now available in select markets, including the United States, with UL certification for safety and compliance, meeting the needs of stringent regulatory frameworks.
A Strategic Evolution in MLPE Technology
The enhanced 725W TS4-A-O is the latest chapter in the TS4 legacy, building upon years of proven technology, field reliability, and installer-friendly design. Designed to handle short-circuit currents of up to 22 Amps and input voltages up to 80V per module, this updated MLPE device offers a significant increase in capacity and performance compared to its predecessors. This is particularly important as many of the latest solar modules push past 600W, a trend driven by the demand for fewer modules per system and increased energy yield in limited-space installations.
By scaling the TS4-A’s power capabilities, Tigo is ensuring that installers do not have to compromise on module selection. This move positions Tigo as a strategic enabler in the transition to more powerful and efficient solar systems. The new TS4-A model accommodates emerging ultra-high-power modules while preserving the simplicity, speed, and safety features that define the product line.
Simplified Installation, Superior Compatibility
Tigo’s engineering approach to this upgrade goes beyond raw electrical performance. The 725W TS4-A-O continues to support Tigo’s hallmark 10-second, bolt-free installation design, which significantly reduces on-site labor and balance-of-system (BOS) costs. The frame-mounted design simplifies logistics and streamlines installation, which is critical for both small-scale residential jobs and large commercial deployments.
Compatibility remains a key theme for Tigo. The new product retains support for a wide range of string inverters, including those featuring Tigo Enhanced functionality. It also supports plug-and-play interoperability with existing Tigo TS4 components, ensuring that customers with existing Tigo infrastructure can upgrade without starting from scratch. Furthermore, it is fully compatible with the Tigo Access Point (TAP), the Cloud Connect Advanced (CCA) data unit, and Tigo’s RSS Transmitters, ensuring seamless integration into new or existing Tigo ecosystems.
Advanced Safety and Shutdown Capabilities
With the increasing adoption of solar energy systems in urban areas and densely populated environments, safety standards are under constant scrutiny. The new 725W TS4-A product line brings with it a robust and highly reliable safety feature set, including Multi-factor Rapid Shutdown (MFRS) technology. This advanced capability ensures multiple layers of redundant rapid shutdown protection—far exceeding the minimum regulatory requirements of NEC 690.12 standards for 2017 and 2020.
This makes the 725W TS4-A-O a particularly strong fit for safety-critical applications such as hospitals, schools, and commercial buildings where enhanced fire safety measures are a must. When combined with a UL PVRSS-certified inverter or a Tigo-certified built-in transmitter, these devices ensure complete compliance with applicable rapid shutdown codes while providing peace of mind to installers, inspectors, and system owners alike.
A Global Response to Market Needs
Tigo Energy’s innovation is deeply informed by installer feedback and market trends. As the company’s Senior Director of Validation, Growth, and Product Management, Gal Bauer, noted:
“Adding key upgrades to the electrical specs and in-demand features with this evolution of the TS4 product family answers the requests we have received from customers across the globe. The primary impetus for developing an update to the TS4-A family is to stay just ahead of the module performance curve and to load those products up with the features the market wants.”
Indeed, this market-responsive development philosophy has been a consistent part of Tigo’s approach to product innovation. In launching the 725W model, Tigo is not only future-proofing solar installations but also reaffirming its commitment to continuous improvement, reliability, and customer satisfaction.
The company also emphasizes durability and long-term value. Tigo’s TS4-A MLPE devices, including the new 725W version, are backed by an industry-leading warranty and manufactured with a commitment to reducing failure rates—already far below the industry average. This makes Tigo products especially appealing to project developers and EPCs seeking dependable long-term performance with minimal maintenance requirements.
Applications Across Residential, Commercial, and Industrial Sectors
The scalability of the TS4-A platform is one of its strongest selling points, and the new 725W device amplifies this benefit. In residential installations, homeowners often face constraints related to roof space or shading. With a higher-wattage MLPE option, installers can deploy fewer modules to meet energy needs or maximize production within limited space.
In commercial and industrial contexts, where array sizes are much larger, the 725W TS4-A offers significant gains in system efficiency and design flexibility. Fewer devices are needed per watt of capacity, and high-current support ensures full compatibility with cutting-edge solar modules coming out of Tier 1 manufacturers.
Whether a project calls for new construction or a retrofit, Tigo’s newest MLPE solution is poised to deliver reliable performance at scale.
Backward Compatibility & Continuity
In line with Tigo’s philosophy of preserving value for existing customers, the 725W TS4-A-O maintains backward compatibility with previous TS4 models. Installers familiar with the TS4-A installation process will find that nothing has changed in terms of physical layout or communication protocols. This seamless product continuity significantly lowers the learning curve and allows for mixed-use scenarios in arrays where module types vary.
Moreover, the new product retains all features that installers and system owners have come to expect from Tigo: module-level monitoring, optimization (in the TS4-A-O variant), and safety shutdown functionality. This uniform experience reinforces Tigo’s position as a reliable partner in solar innovation.
Supporting Tools and Services
Tigo’s technology suite doesn’t end with hardware. Installers and system operators can take advantage of powerful data analytics via the Tigo Energy Intelligence software platform. When paired with the CCA and TAP devices, the 725W TS4-A model feeds performance data into the cloud for real-time diagnostics, remote troubleshooting, and ongoing energy management.
Tigo also offers support through its Green Glove service—a value-added program designed to assist installers and developers on large-scale projects. This service includes engineering support, commissioning help, and access to Tigo’s technical expertise to ensure successful deployment and performance over the life of the project.
Availability and Next Steps
The 725W TS4-A-O is now shipping to markets requiring UL-certified MLPE products, including the United States. Global availability is expected to expand in line with regional certification timelines and market demand. Installers, developers, and EPCs interested in leveraging this technology can contact the Tigo sales team directly for purchasing options and project consultations.
