The Few Bets That Matter
Concentrated Equity Investor, AI Infrastructure
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.comÂ
SolarEdge is being re-rated on a solar demand rebound, improved technology, a new B2B business and potential as an AI data center play through its SST and inverters, with the Iran conflict acting as a catalyst. It trades at 2.5x sales versus Enphase at 5.8x, a gap that should close as its technology improves, even before counting B2B scaling or SST revenue and the premium of becoming an AI play. x.comÂ
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.comÂ
Solar stocks are trades, not investments, because the industry is a perennial long-term loser despite the continued growth of solar power. As Warren Buffett said of airlines, the urge to invest should be resisted no matter how attractive Enphase, Sunrun, First Solar, SolarEdge, Nextracker, Array Technologies, Canadian Solar or even a broad solar ETF may look. That holds even as @optionscjp notes Enphase is turning toward commercial data center projects. x.comÂ
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.comÂ
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.comÂ
Nebius has pricing power because its hard-to-build AI infrastructure and software serve enterprise clients who cannot find capacity elsewhere. It owns some data centers and land but has mostly operating leases; the share of active compute at owned sites is unspecified. It looks like the best infrastructure play despite slight skepticism about its path to profitability and valuation, and would work even if capex slowed 20% or the cycle paused. x.com x.com x.comÂ
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.comÂ
T1 Energy is undervalued as an essential power provider for the AI boom, with an aggressive 18-month target of $18 against an average analyst target of $9.00-10.25. As hyperscalers hit a power bottleneck, its pivot to US solar manufacturing, battery storage via the KORE Power acquisition and possible data center repurposing make it a high-conviction growth play. The target assumes successful G2 Austin execution, positive EBITDA in 2027 and a lasting premium for US AI-adjacent energy names. x.com … Show more
Solaria Energia y Medio Ambiente, a Spanish energy provider for data centers first picked by @origoinvest, is about to see quite explosive growth in its data-center business. Management talks nonstop about batteries enabling that growth. x.comÂ
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
