Tigo Energy Achieves PPDS P4 Certification, Expanding Three-Phase EI Inverters and Residential Solutions in Czech Republic
Tigo Energy, Inc. (NASDAQ: TYGO), a leading provider of intelligent solar and energy software solutions, has announced the successful certification of its entire portfolio of three-phase Tigo EI Inverters under the PPDS P4 protocol requirements in the Czech Republic. This milestone opens the door for grid connection of Tigo’s inverters in one of the European Union’s most robust markets for solar energy adoption. Compliance with PPDS P4—formally known as Distribution System Operation Rules, Annex 4—is a critical prerequisite for connecting solar inverters to the Czech grid, ensuring alignment with technical standards set by the European Commission and adopted by local utility providers.
This achievement reinforces Tigo’s position as a trusted leader in the rapidly growing solar-plus-storage sector. With nearly 107MW of Tigo’s Module-Level Power Electronics (MLPE) deployed in the Czech Republic in 2024 alone, the company has solidified its reputation among thousands of installers who rely on its innovative solutions. The successful PPDS P4 certification not only validates Tigo’s technological compatibility but also positions the company to expand its offerings, particularly with the introduction of the Tigo EI Residential system.
Tigo EI Residential: A Comprehensive Energy Solution
The release of the Tigo EI Residential system marks a significant step forward in addressing the growing demand for integrated solar, storage, and energy management solutions. In 2024, the Czech Republic added 967MW of primarily residential rooftop solar capacity, underscoring the nation’s commitment to renewable energy adoption. Tigo’s EI Residential system is designed to meet this demand by providing an all-in-one solution that combines every aspect of energy generation, storage, and management into a cohesive package.
At the heart of the EI Residential system are Tigo’s TS4 Flex MLPE devices, which ensure module-level optimization and safety. The system also features single- and three-phase inverters, modular battery storage, and the innovative EI Link—a compact cabinet that consolidates all system wiring, communication, and backup functionality. Beyond solar and storage, Tigo integrates additional smart home technologies, such as the GO EV Charger for electric vehicle charging and the GO Junction for managing heat pumps. These innovations deliver a scalable, future-proof solution tailored to the needs of modern, energy-conscious homeowners.
“The certification of our inverters for operation on the Czech grid means installers now have access to a reliable, all-in-one solution that is both easy to install and highly configurable,” said Miroslav Vavera, CEO of SUNLUX s.r.o., a prominent solar installer in the region. “With Tigo’s Energy Intelligence software platform, we can proactively monitor system performance, streamline maintenance, and ensure uninterrupted energy security for homeowners. Batteries are no longer just optional add-ons—they are essential components of energy independence, seamlessly managed through an intuitive app.”
Streamlined Installation and Enhanced Installer Experience
Tigo’s focus on improving the design, installation, and commissioning processes has been guided by insights gained from hundreds of engagements through the Tigo Green Glove Service Program. This initiative underscores the company’s commitment to Total Quality Solar, ensuring that installers benefit from streamlined workflows, reduced setup times, and enhanced self-sufficiency during system deployment and troubleshooting.
Key enhancements include simplified commissioning flows within the Tigo EI Residential Solar Solution, which reduce manual steps and improve system integration across Tigo inverters, batteries, and the EI Link. Installers also gain access to tools and resources that simplify troubleshooting and optimize system performance, resulting in greater reliability and customer satisfaction. These improvements not only enhance the installer experience but also ensure that homeowners receive a high-performing, future-ready energy system.
Momentum Across Europe
The expansion of the Tigo EI Residential solution into the Czech Republic highlights the growing momentum of integrated solar-plus-storage systems across Europe. As one of Tigo’s strongest global markets, the Czech Republic represents a key opportunity to bring advanced energy solutions to homeowners and professionals alike.
“This certification is another testament to the value of Tigo’s integrated home energy systems,” said Jing Tian, Chief Growth and Revenue Officer at Tigo Energy. “By delivering real benefits to Czech homeowners and empowering skilled installers with cutting-edge tools, we are helping drive the energy transition forward in Europe.”
Engaging the Czech Solar Community
To further engage with the Czech solar community, Tigo is hosting several events and webinars designed to provide hands-on experience and deeper insights into the EI Residential Solution. Installers are invited to attend the Iftech Solar Fvest in September 2025, organized by Tigo’s distribution partner Iftech. This all-day event will allow participants to explore the EI Residential system firsthand and learn about its advanced features. Additionally, Tigo is offering a Czech-language webinar for solar installers in July, providing an opportunity to engage with experts and understand the system’s capabilities.
