Enphase's US home-solar demand still has not stabilized, delaying its potential home-power recovery to 2027. Q4 revenue guidance of $225-255M is about 20% below the Street at the midpoint, and guided gross margin falls to 40-43% from 45%. Higher electricity costs from AI demand could eventually favor homes generating and storing power; its IQ Battery 5G stores about 50% more energy and costs about 40% less to make. The next two quarters look tough. x.com  x.com 

Enphase is still a business in contraction: Q2's sequential improvement came almost entirely from safe-harbor shipments booked ahead of tax-credit deadlines, not returning end demand. Those deals pull volume forward, and a tariff refund after the Supreme Court voided IEEPA tariffs flattered GAAP results one time. US revenue, the large majority, is still shrinking. The IQ Solid-State Transformer is an interesting second act, but one clean demand-driven quarter is needed first. x.com 

Enphase Energy should return to the $70s or higher soon on its solid-state transformer for AI data centers. Enphase says power modules for its IQ Solid-State Transformer are being built in Texas to assemble and validate full-scale racks that convert medium-voltage AC directly to 800 VDC, reducing the need for battery buffering near AI compute racks. The announcement is not new to anyone following the earnings calls, which explains the earlier run-up. x.com  x.com 

Enphase Energy's declining revenue and EPS make the stock's hype unwarranted. If it cannot perform during the most severe energy shortage in decades, it is hard to see when it will. x.com 

SolarEdge could re-rate from a broken solar story to an emerging AI data-center infrastructure play sooner than expected. It set a $600M solid-state transformer revenue target for 2029, far above a ~$250M base case for 2030, and its 800 VDC conversion stage is running under load in the lab, keeping a working system on track for end-2026. A joint white paper with NVIDIA adds credibility, though NVIDIA does not endorse it and there is no pilot customer or order yet. It is a 2027-2028 play. x.com  … Show more

Enphase and SolarEdge, dead home-solar stocks, have a credible path through a pivot to solid-state transformers, which @tailrisked calls the future of grid technology. It remains a very speculative play warranting only small positions. x.com 

Enphase looks expensive against its earnings, at 35x trailing and 16x next year's versus about 8x for solar companies. Applying 8x to next year's $2.27 EPS gives fair value of roughly $16.50-$21, and the stock trades 69% above the top of that range. The valuation leans on forecasts, with forward earnings 125% above trailing. This is a levels-only read from reported earnings and estimates, without fundamental work. x.com 

Wall Street is still underestimating T1 Energy, America's first vertically integrated silicon-based solar company, which is powering the AI data center buildout with domestic clean energy. x.com 

Enphase and SolarEdge are a paired bet on AI data center power electronics. Both bring deep bidirectional conversion and safety expertise from residential and microgrid markets, which data centers need for sudden power swings as GPU clusters cycle and for fail-safe protection where one breaker failure can destroy a rack. Direct 13 kV-to-800 V solid-state transformers are about two years out, so both look only partly noticed after correcting to attractive multiples. SolarEdge is slightly ahead. … Show more

Navitas Semiconductor's GaN chips address the power bottleneck in AI data centers, where rising GPU power draw has pushed silicon power chips to their physical limits. Its CEO puts GaN's design value at $10,000-$15,000 per MW, and high-power market revenue rose 35% year over year in Q1. After a brutal 2025 of weak consumer demand, dilution and losses, the Navitas 2.0 pivot and Q1's return to sequential growth suggest the worst is over, with its AI power line moving into system validation. x.com
