Tigo Energy makes Module Level Power Electronics (MLPEs) — small devices that attach to individual solar panels to perform optimization, monitoring, and safety functions. MLPEs account for roughly 90% of revenue and are sold under the TS4 Flex brand, which works across residential, commercial & industrial, and utility-scale solar installations using a single SKU. Tigo's open-architecture design is compatible with nearly any inverter or module brand, which it argues gives it an advantage over more proprietary competitors. Beyond MLPEs, Tigo sells GO Energy Storage Solutions (GO ESS), a modular residential solar-plus-storage product line including batteries, inverters, and EV chargers, which accounts for roughly 7% of revenue. Tigo also offers Predict+, an AI-based energy demand forecasting SaaS platform for utilities and grid operators, though it remains a small slice of total revenue. Tigo sells primarily through distributors and large solar installers, with no single customer representing 10% or more of sales. Manufacturing is fully outsourced to contract manufacturers in Thailand and China. Geographically, EMEA drives roughly two-thirds of revenue, with the Americas at about a quarter. A growing focus for Tigo is the solar repower market — retrofitting aging installations — where its open architecture is well-suited for integrating with existing system components. In the U.S., Tigo is pursuing residential market share through a domestic manufacturing partnership with EG4 Electronics to produce ITC-qualified, domestic-content-eligible co-branded optimized inverters.
