Tigo Expands Repowering Solutions for Smaller Residential Solar Systems — Tigo Energy, Inc.

Event summary

Tigo launched a 3.8kW EI Inverter with Inverter Power Output Control (IPOC) for smaller residential solar systems, targeting legacy systems in the Midwest.
The solution is designed to avoid costly permitting or electrical upgrades during repowering, addressing a growing need for 3–4 kW systems.
Approximately 400,000 U.S. residential solar systems are over a decade old, driving demand for cost-effective repowering solutions.
Tigo will showcase its repowering strategies at the Zonna Solar Conference on April 21–22, 2026, in Berlin, Ohio.

The big picture

Tigo’s expansion into smaller residential repowering solutions addresses a critical gap in the solar industry, where aging systems require upgrades without costly overhauls. As the Midwest’s solar infrastructure matures, the ability to extend system life through flexible inverter technology could become a key differentiator for installers and homeowners alike. The company’s focus on real-world constraints like permitting and panel capacity aligns with broader industry trends toward cost-effective, scalable solar solutions.
