Enphase Energy Jumps After Barclays Upgrade and Launch of New Microinverter

Shares of ENPH saw a notable premarket spike of 6.7% on Thursday, fueled by an upgrade from Barclays and the debut of its latest commercial microinverter product.

Barclays analyst Christine Cho shifted her call on Enphase from Underweight to Equalweight, hiking the price target to $51 from $30. The update hinges on the potential of Enphase's solid-state transformer (SST) technology, which Barclays projects could tap into a roughly $2 billion annual U.S. market by the end of the decade.

Cho highlighted Enphase's move into the data center power arena, citing the emerging trend of hyperscalers adopting 800V DC architectures. These setups demand components like SSTs to replace conventional transformers and power distribution units. Since SSTs function similarly to inverters with active power conversion, they align well with Enphase's core strengths.

The analyst also noted that if Enphase keeps its competitive edge alongside peers like SolarEdge, it stands to gain early market share as 800V data centers grow through 2028 and 2029.

Separately, Enphase announced the start of production shipments for its IQ9S-3P Commercial Microinverter in the U.S. This device leverages gallium nitride (GaN) technology, supporting solar panels up to 770 watts. It connects directly to three-phase 480Y/277-volt grids without needing external transformers, delivering a continuous output power of up to 548 VA with an efficiency rating of 97.5% (CEC weighted).

The IQ9S-3P carries a 25-year limited warranty and is produced in U.S. facilities, positioning it to possibly qualify for domestic content bonus tax credits under current regulations. Meanwhile, the company is accepting safe harbor orders for this product until July 4, 2026, ahead of federal tax credit deadlines.

This combination of strategic upgrades in product offerings and a more bullish assessment from Barclays helped energize Enphase's shares, reflecting investor interest in the company's innovations and long-term market opportunities.

Time will tell how much ground Enphase can carve out in the evolving data center and solar tech sectors, especially with emerging technologies reshaping traditional power infrastructure.
