Tigo Energy Expands EI Residential Platform With Smart Heating Integration, Introduced At Intersolar Europe

Tigo Energy, Inc., a leading provider of intelligent solar and energy software solutions, will be showcasing its latest innovations for both residential and Commercial & Industrial (C&I) solar installers at Intersolar Europe, which will take place in Munich, Germany, from May 7 to May 9. Among the key products that will be highlighted is the new Tigo GO Junction, a significant addition to the EI Residential solar and storage ecosystem. The GO Junction serves as the critical connection between photovoltaic (PV) generation, energy management, and home heating, completing Tigo’s residential energy solution.

Over the past five years, Germany has installed more than one million heat pumps, with projections indicating that the country will reach up to ten million units by 2030. This marks a phase of convergence between clean energy and smart technologies in the residential heating market. With this shift, systems are now able to intelligently manage PV production, energy storage, and household energy demands, offering a way to accelerate the transition to solar while addressing the economic burden of rising heating gas costs.

In response to this growing demand, Tigo introduces the GO Junction to the European market as a cutting-edge device that extends the EI Residential ecosystem to include smart heating. Similar to the way the Tigo GO EV Charger integrates e-mobility into the residential energy system, the GO Junction enables the seamless integration and intelligent management of third-party heat pumps within the Energy Intelligence software platform. This marks the completion of a fully integrated home energy system from Tigo.

At Intersolar Europe, Tigo will have a fully operational EI Residential system on display, providing a comprehensive solution that integrates solar generation, energy storage, and energy management. This system will include TS4 Flex MLPE, single- and three-phase inverters, modular battery storage, and the EI Link, a compact unit that consolidates all system wiring, communication, and backup functionality into one.

Visitors to the booth will have the opportunity to explore the two latest extensions to the Tigo ecosystem: the GO EV Charger, which allows for the direct integration of e-mobility into the platform, and the brand-new GO Junction, which introduces smart heating capabilities into the energy management framework. Together, these innovations demonstrate how the EI Residential system has evolved into a complete energy solution for modern homes that is both smart and scalable, ready to support the ongoing energy transition.

Georg Kreitmair, Managing Director at Weiss-Blau GmbH, a Tigo-Advanced Installer in Germany, said in a statement, “We know the EI Residential solution well because we’ve been installing it regularly for some time, and we have always appreciated the reliability and integration between all of its components. A direct connection to the heat pump was the next logical step, but it was also increasingly requested by customers focused on maximizing self-consumption. With the arrival of the Tigo GO Junction, we can now deliver a truly holistic solution where energy generation, storage, and management work together in a simple and coordinated way. A fully integrated Tigo system also makes installation more straightforward and brings real added value to the end user.”

Mirko Bindi, Senior VP of Sales EMEA & MD Europe at Tigo Energy, mentioned, “The Tigo GO Junction represents more than a technological evolution, it’s a solution that originates directly from the experiences and needs the installers who work with our systems daily shared with us. By turning installer input into real solutions through ongoing dialogue, we close an important feedback loop with the market. Our commitment to Total Quality Solar (TQS) guides us in delivering excellence at every stage of the solar supply chain–from product development and manufacturing to installation and long-term serviceability. As a continuous process, the TQS spirit defines the standard to which we hold our operations, even beyond the corporate walls.”

Additionally, European PV professionals attending Intersolar Europe will be able to learn about the full range of TS4 Flex MLPE products, including the TS4-X. The TS4-X is a powerful new platform designed to meet the requirements of high-power solar modules. It combines optimization, monitoring, and rapid shutdown functionality—or a combination of these features—into one flexible device.

All performance data, including the amount of energy reclaimed through optimization, is accessible through the Energy Intelligence software platform. This platform provides both installers and system owners with enhanced control, comprehensive diagnostics, and smarter energy management across the entire solar fleet.
