Tigo Energy, Inc., a global leader in smart solar and energy software solutions, has announced that its complete range of three-phase Tigo EI Inverters has received official certification for compliance with the PPDS P4 standards in the Czech Republic. This certification, part of the Distribution System Operation Rules (Annex 4), is crucial for connecting solar inverters to the Czech electricity grid and confirms that Tigo’s inverters meet the technical criteria set by the European Commission and recognized by local utilities.
This achievement comes at a time when rapid shutdown requirements are becoming increasingly common across Europe. In the Czech Republic alone, nearly 107 MW of Tigo’s Module Level Power Electronics (MLPE) solutions were deployed in 2024, contributing to the company’s strong track record with thousands of local installers over the past decade.
Building on its trusted market presence, Tigo has launched its EI Residential system in the Czech Republic to meet the rising demand for home solar systems. In 2024, the country added 967 MW of residential rooftop solar capacity, creating a solid foundation for this rollout. The EI Residential system provides a comprehensive energy solution, integrating solar power generation, battery storage, and advanced energy management into a single platform.
Miroslav Vavera, CEO of SUNLUX s.r.o, commented, “Tigo securing this certification for inverter operation on the Czech grid means that installers like us now have a reliable, all-in-one solution that is easy to install and configure, featuring a flexible, modular architecture that meets diverse residential customer needs. Tigo also provides proactive monitoring through the Energy Intelligence software platform, significantly streamlining our operations and maintenance. For homeowners, this ensures a system that delivers energy security even during outages, transforming batteries from optional add-ons to essential components of energy independence, all easily managed via a user-friendly app.”
Jing Tian, Chief Growth and Revenue Officer at Tigo Energy, noted, “As one of our strongest global markets, the expansion of the Tigo EI Residential solution into the Czech Republic signifies that integrated solar-plus-storage from Tigo is gaining momentum across Europe. This certification enables us to offer the benefits of an integrated home energy system to Czech homeowners and the skilled professionals who serve them.”
The system includes TS4 Flex MLPE, single- and three-phase inverters, modular batteries, and the EI Link, which consolidates system wiring, communication, and backup functions within a single compact cabinet. Tigo has also introduced the GO EV Charger, which integrates electric vehicle charging directly into the EI system, and the GO Junction, which connects heat pumps for improved home energy efficiency. These features allow homeowners to manage their energy use in a smart, flexible manner while supporting the transition to cleaner living.
To further assist Czech installers, Tigo has implemented significant enhancements to the installation and commissioning processes, informed by feedback from hundreds of professional interactions through the Tigo Green Glove Service Program. The new system setup process is faster and more intuitive, requiring fewer manual steps and tools, empowering installers to deploy and maintain systems independently.
Installers and PV professionals in the Czech Republic can access a full directory of certified Tigo solar installers online. They are also invited to experience the EI Residential system in person at the Iftech Solar Fest in September 2025, organized by Iftech, Tigo’s distribution partner, providing an opportunity to explore the platform’s features and benefits firsthand.
