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 

SolarEdge's push into data centers is a massive opportunity, with potential Nebius-like returns if it executes, though that may take a long time. It has laid out a $600M SST revenue target by 2029. The market isn't buying the story yet given execution risk and how slowly its residential battery business has recovered. x.com  x.com 

SolarEdge's solid-state transformer technology is well documented and seemingly non-speculative, yet it trades at an anomalous 2x sales versus about 4x for transformer maker Hammond Power. Per @aakashgupta, transformer lead times of up to five years are gating US AI data centers: of 12 GW of 2026 capacity announced, only 5 GW is under construction. 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

SolarEdge and Enphase are both best positioned for solid-state transformers, and both are mid-term accumulation candidates, with no preference yet between them. Per a post the author replies to, Enphase uses Infineon's GaN bidirectional switches for its SST. Their charts suggest the monster move can continue. x.com  x.com 

Monolithic Power Systems is more critical to NVIDIA's roadmap than people understand, and the Street looks too light on its revenue growth and margin expansion. It is expected to keep 80%+ share on NVIDIA's Hopper and Blackwell platforms, is collaborating on the 800 VDC data-center power architecture and is expected to be a major supplier for Vera Rubin and the Kyber rack. The stock is breaking out to an all-time high and is spendy on multiples, so it needs a 24+ month hold. x.com 

Alpha and Omega Semiconductor is a promising business at the wrong price: its rerating on Nvidia AI-power hype rests on a narrative management has already walked down. The stock is up about 128% in a year to $44.45, near its 52-week high, as retail frames it as the cheapest catch-up in the 48V-to-12V power shift, citing alleged Nvidia GB300 DrMOS allocation. Yet the 800V supply chain is hard to win, with its bottleneck in silicon carbide and gallium nitride held by a few incumbents. x.com  x.com  … Show more

Enphase, SolarEdge and Fluence are being sold while their order books grow. Power consumption is expected to rise 65% in a year, yet these energy stocks fell 10% or more in a day; the market just does not see the demand yet. x.com 

Nvidia delivered everything investors wanted, yet trades at only 13x its 2029 EPS power of $22 after underperforming the semiconductor sector by 50% this year. It derisked gross margins, guided to 70% total revenue growth in 2028 versus 45% expected and gave more transparency on third-party financing. Supply should stay short of demand through 2028. x.com 

Enphase is asking for a re-rate before transforming its business, which fundamentally does not work. It sells rooftop hardware to homeowners who just lost the tax credit, and Q1 revenue fell 20% year on year. Its GaN and custom-ASIC power platform for AI is credible engineering, but volume is not until 2028 and the solid-state transformer has zero named customers. Management saying investors value it wrong is the label trying to go first; utility-scale T1 Energy is preferred in solar. x.com
