Solar Market Loses $260 Million in a Day: What Happened to U.S. Inverter Stocks?

SolarEdge Technologies Inc. (NASDAQ: SEDG), a U.S. solar inverter manufacturer, plummeted 7.61% on the Nasdaq on the 5th, closing at $45.04 and erasing approximately $192 million in market value—about ₩260 billion.

Trading volume exceeded 2.16 million shares, shrinking the company’s market capitalization to roughly $2.7 billion (about ₩3.7 trillion).

Today’s drop reflects a broad risk-off mood in the solar inverter sector, driven by concerns over cash burn, fierce competition, and margin pressure from roughly 5% tariffs.

SolarEdge has been ramping up inverter production for the U.S. and European markets, launched its next-generation residential “Nexis” solar-plus-storage system in Germany, and expanded its manufacturing footprint in the U.S. In March, the company also announced that CFO Asaf Alperovitch plans to depart in June.

Headquartered in Israel and the U.S., SolarEdge specializes in smart energy and solar inverter technologies, leveraging DC-optimized inverters and energy management solutions to grow its global market share.

However, after a 2023 glut of inventory and order cancellations in Europe led to weak results and a sharp share-price decline, the company has faced investor lawsuits, structural overhauls, and production restructuring—making it a notably volatile stock.
