SolarEdge Shares Climb as NVIDIA 800 VDC Collaboration Headlines Analyst Day; Solar Peers Enphase and First Solar Slip
SolarEdge Technologies drew investor attention Thursday as the company hosted its analyst day, where it highlighted a joint technical paper with NVIDIA focused on 800 VDC (800-volt direct current) power architecture. The news landed amid a mixed session for listed solar names, with inverter maker SolarEdge trading higher while two peers moved in the opposite direction.
SolarEdge Technologies (SEDG) was changing hands at $36.43, up 5.94% from its previous close of $34.39, valuing the company at roughly $2.28 billion. The company, which sells power optimizers, DC-to-AC inverters, and storage products including its Home Battery 400V and CSS-OD solutions, operates across the United States, Europe, and other international markets.
The collaboration with NVIDIA centers on 800 VDC power distribution, a high-voltage direct current architecture that is drawing interest from data center operators seeking to move more power over fewer conductors as computing demand grows. A joint technical paper does not itself represent a commercial contract, but it signals that the two companies are aligning on specifications for next-generation power delivery, a domain where inverter and power electronics specialists like SolarEdge have transferable expertise.
Elsewhere in the sector, the session was softer. Enphase Energy (ENPH), which designs semiconductor-based microinverters and home energy systems, traded at $36.72, down 5.75% from a prior close of $38.96, putting its market capitalization near $5.16 billion. Enphase’s microinverters convert direct current from individual solar panels to grid-compatible alternating current at the panel level, a residential-focused approach that contrasts with SolarEdge’s optimizer-plus-inverter architecture.
First Solar (FSLR) also declined, last quoted at $203.10, off 4.85% from a previous close of $213.45, for a market cap of approximately $23.11 billion. First Solar manufactures thin-film photovoltaic modules and sells utility-scale solar solutions in the United States, France, India, Chile, and other markets — a business model upstream of the inverter makers, positioned at the module-manufacturing stage of the solar value chain.
The divergence underscores how differently investors are treating the residential and commercial power-electronics segment versus module manufacturing on a given trading day. SolarEdge’s analyst-day presentation gave shareholders a venue to assess the company’s product roadmap and strategic direction, with the NVIDIA paper serving as the marquee disclosure of the event.
What to watch
- Any follow-up from SolarEdge quantifying commercial activity tied to the 800 VDC architecture work with NVIDIA.
- Upcoming quarterly earnings reports and guidance from SolarEdge, Enphase, and First Solar.
- Demand indicators in the residential solar market, which affect both inverter makers’ order books.
- Utility-scale procurement trends relevant to First Solar’s module backlog.
