AI Data Center Theme Gains Momentum... Solar Stocks Rebound 5% After Previous Plunge

Enphase Energy Inc. (ENPH) extended its short-term rebound, closing at $45.25 on the U.S. stock market, up 5.06%. Trading volume reached approximately 4.2 million shares, higher than usual, and market capitalization rose by about $320 million (roughly ₩440 billion) in a single day to around $5.96 billion (about ₩8.3 trillion).

The company recently joined the Open Compute Project as a Platinum member to collaborate on power standards for AI data centers and launched its new IQ9 series microinverters, built with GaN technology, in the U.S. and Europe—targeting both data center and residential solar demand.

With its second-quarter earnings release scheduled for late July, expectations for a second-half demand recovery following inventory adjustments are gradually being reflected in the stock price.

Headquartered in Fremont, California, Enphase Energy is a global energy technology firm supplying solar microinverters, residential and small-business battery systems, and energy management software. Leveraging its distributed power-conversion technology, the company has secured a leading share of the residential solar market and is now expanding into EV charging and AI data-center power infrastructure to drive further growth.
