OSLO, Norway--(BUSINESS WIRE)-- Otovo ASA (Euronext Oslo Børs: OTOVO; “Otovo”), a leading provider of behind-the-meter energy services for homes and businesses, today announced it has completed 1,000 inverter replacements using technology from Tigo Energy, Inc. (Nasdaq: TYGO). This milestone marks a new phase in Otovo's repowering business, which restores power for homeowners and businesses with aging or orphaned solar systems.

Highlights

• Otovo has now completed 1,000 inverter replacements using Tigo technology.
• Nearly 400,000 U.S. residential solar systems reach the 10-year age mark every year for the next five years. More than one million systems have already passed that mark.
• Tigo's open architecture allows Otovo to service many types of legacy solar systems, not just one brand.
• Tigo Inverter Power Output Control lets Otovo match new equipment to each system's original requirements.
• The partnership supports Otovo's strategy of restoring service to aging and orphaned solar systems at scale.

"Otovo's mission is to build the world's leading home energy service platform," said William J. (John) Berger, CEO of Otovo. "Reaching 1,000 inverter replacements shows that our repowering business is working. Tigo's technology gives our teams the flexibility to handle many types of legacy solar systems. For homeowners with aging or orphaned systems, that flexibility helps us get them producing power again quickly."

"The installed base of solar is now large enough that repowering needs to become a core service discipline for installers," said Zvi Alon, chairman and chief executive officer of Tigo Energy. "Otovo shows what this opportunity looks like at scale. Companies like Otovo prove there is real demand for a repeatable way to repower aging systems and get customers back online."

Otovo uses the Tigo EI Inverter and TS4 Flex MLPE products to service a wide range of legacy solar systems. These open systems give Otovo's technicians module-level monitoring and rapid shutdown on every job. The Tigo EI Inverter's wide voltage range and compact design help Otovo's teams fit more repowering projects with fewer equipment constraints. Using Tigo Inverter Power Output Control (IPOC), Otovo's technicians set the right power output for each site during setup in the field. Together, these tools help Otovo match new equipment to each system's original requirements and simplify complex repowering jobs for its customers.

The need for repowering is growing quickly. Nearly 400,000 U.S. residential solar systems will reach the 10-year age mark every year for the next five years. More than one million systems have already passed that mark. As the installed base ages, homeowners increasingly need help with failed equipment, discontinued products, changing energy needs, and orphaned systems left behind by installers that have gone out of business. Otovo's platform, powered by its proprietary Endurance^™ AI system, is built to meet this need at scale.

Key Terms

behind-the-meter technical

Equipment or systems located on a customer’s side of the electricity meter—such as rooftop solar panels, battery storage, electric vehicle chargers, or energy controls—that generate, store, or manage power for use on-site rather than being supplied through the utility’s grid. Investors care because behind-the-meter assets change how much power a customer buys, can create new revenue or savings streams, affect demand patterns, and shift regulatory or business models in the energy market, much like a homeowner installing their own water tank reduces municipal supply needs.

mlpe technical

Module-level power electronics (MLPE) are small devices—like tiny smart adapters—attached to each solar panel to optimize and monitor its output individually, instead of managing the whole array as one. For investors, MLPE can meaningfully change a solar project’s performance, operating costs and product competitiveness because they boost energy yield, improve fault detection and can alter installation and maintenance economics.

rapid shutdown technical

A rapid shutdown system is a safety feature for solar panel installations that quickly cuts the electrical output of rooftop modules during emergencies so wires and panels become low‑voltage and safer to handle. Investors should care because required compliance, equipment choices, and installation costs affect product demand, project timelines, and liability exposure—think of it as a car’s airbag: a mandated safety add‑on that influences design, price and marketability.
