Tigo EI Residential solution attains national compliance certification for solar inverter operation in Slovakia, delivering reliable solar, backup power, and seamless energy management.

LOS GATOS, Calif. & ROŽŇAVSKÉ BYSTRÉ, Slovakia — Tigo Energy, Inc. (NASDAQ: TYGO), a key player in intelligent solar and energy software solutions, announced today a major win: its three-phase Tigo EI Residential solution has passed rigorous compliance testing with flying colors in Slovakia. This achievement, conducted in partnership with Východoslovenská distribučná, a.s. (VSD), Slovakia’s distribution system operator, isn’t just a regulatory hurdle cleared; it’s a powerful validator. It greenlights Tigo’s tech for integration with the Slovakian grid, underscoring the company’s commitment to delivering energy solutions that are not only cutting-edge but also safe and grid-friendly.

The Tigo EI Residential Three-Phase Inverters (TSI-6K3D, TSI-10K3D, TSI-15K3D) proved their mettle by demonstrating their ability to perform a controlled shutdown during voltage dips, effectively preventing unwanted energy feed-in—a crucial safety feature. Compliance with Slovakian standards like Act No. 251/2012 on Energy and Decree No. 275/2012 on electricity distribution quality is paramount. Pair these inverters with the Tigo EI Battery, and you’ve got a dynamic system that optimizes energy consumption and maximizes backup potential. Think enhanced flexibility and unparalleled energy visibility for the homeowner.

Miroslav Urban, CEO at CMS-turnkey, emphasizes the comprehensive nature of the Tigo EI Residential system. “It’s a complete energy solution streamlining our work and delivering tangible value, including the smart integration of performance optimization and key safety functions.” He further notes the user-friendly design, allowing for swift and intuitive installations. “The backup system delivers resilience, allowing multiple home loads to remain active even when the grid fails….homeowners get a smarter energy system with advanced monitoring and full control via the Tigo app.”

The Slovak residential solar sector is booming, accounting for a significant 43% of overall solar market growth in 2024. Approximately 120 MW of rooftop solar systems were installed across the country. Notably, over 4 MW of these systems include Tigo MLPE (Module Level Power Electronics) solutions. Such a significant adoption indicates a move towards module-level power optimization and advanced system monitoring. This rising trend reveals a broader demand for flexible and future-proof PV solutions.

“Installers are actively seeking solutions that empower homeowners to take control of their energy destiny,” stated Jing Tian, chief growth and revenue officer at Tigo Energy. “The Tigo EI Residential solution, now fully grid-compatible in Slovakia, empowers higher self-consumption, energy independence, and system efficiency. Every kilowatt-hour becomes an asset. We see smart energy choices as the cornerstone of a more resilient and sustainable future.”

The Tigo EI Residential solution’s pièce de résistance? A comprehensive backup system that can simultaneously power multiple household appliances and systems during a power outage. During a major blackout in the Czech Republic earlier this year(June 2025), the Tigo system ensured critical household functions remained operational. Beyond its smooth compatibility with the TS4 Flex MLPE platform, the system seamlessly connects with accessories like the Tigo GO EV Charger and the GO Junction, providing comprehensive energy management across electric vehicle charging and smart home heating applications, all controlled via the user-friendly Energy Intelligence app.

For Slovakian installers and PV system designers, a Czech-language webinar deep-diving into the Tigo EI Residential Solution is available on demand, offering crucial tech insights and system design specific for Central European residential install.
