Tigo Energy's EI Residential Solution Gains National Certification in Slovakia

Tigo Energy's three-phase EI Residential solution has been cleared for deployment in Slovakia after successfully completing mandatory compliance testing with local distribution system operator Východoslovenská distribučná. The solution provides reliable solar, backup power, and seamless energy management, and has been certified for safe operation in line with Slovak regulatory standards. The solution's certification marks a growing trend towards intelligent energy management in the Slovak residential market, with over 4 MW of rooftop solar systems equipped with Tigo MLPE solutions in 2024.

Tigo Energy, Inc. (NASDAQ: TYGO), a leading provider of intelligent solar and energy software solutions, has successfully completed mandatory compliance testing for its three-phase Tigo EI Residential solution in Slovakia. This certification, achieved in partnership with Východoslovenská distribučná, a.s. (VSD), a Slovak distribution system operator, confirms the solution's compatibility with local grid requirements and its adherence to Slovak regulatory standards [1].

The Tigo EI Residential solution offers reliable solar power, backup capabilities, and seamless energy management. The solution includes three-phase inverters (TSI-6K3D, TSI-10K3D, TSI-15K3D) that can safely disconnect from the grid during voltage loss events, preventing unintended power feed-in. When combined with the Tigo EI Battery, the system provides enhanced flexibility, improved energy visibility, and optimized self-consumption and backup capabilities [1].

Miroslav Urban, CEO at CMS-turnkey, highlighted the solution's benefits, stating, "The Tigo EI Residential solution is more than a storage system; it’s a complete energy solution that streamlines our work and delivers tangible value." The solution's compact, all-in-one design facilitates fast and intuitive installation and commissioning, while its backup system ensures resilience, allowing multiple home loads to remain active during grid outages [1].

The certification marks a growing trend towards intelligent energy management in the Slovak residential market. In 2024, the Slovak residential solar sector accounted for approximately 43% of solar market growth, with over 120 MW of rooftop solar systems deployed. Of these, more than 4 MW were equipped with Tigo MLPE solutions, indicating the increasing adoption of module-level power optimization and advanced system monitoring technologies [1].

Jing Tian, chief growth and revenue officer at Tigo Energy, emphasized the solution's potential, stating, "The Tigo EI Residential solution is now fully compatible with the Slovak grid, enabling higher self-consumption, increased energy independence, and greater system efficiency." By optimizing how solar energy is produced, stored, and used in the home, the solution helps turn every kilowatt-hour into an asset [1].

The Tigo EI Residential solution's performance was demonstrated during a widespread blackout in June 2025 in the Czech Republic, where it ensured the continued operation of critical household loads. The solution can be expanded with accessories such as the Tigo GO EV Charger and the GO Junction, enabling intelligent energy management across electric mobility and smart heating applications [1].

Installers and PV system designers in Slovakia are invited to watch a Czech-language webinar on the Tigo EI Residential Solution, now available on demand. The session covers key technical insights and system design considerations tailored to residential applications in Central Europe [1].
