Key Insights
- Tesla Megapack gained qualification under Nvidia’s DSX Ready program.
- Nvidia launched DSX Ready for power and cooling infrastructure.
- Qualification does not guarantee site approval or deployment contracts.
On Sept. 21, Nvidia qualified the Tesla Megapack for its new DSX Ready program, integrating Tesla’s battery systems into AI factory reference designs. This designation covers battery energy storage systems deployed around high-density computing environments.
The development integrates Tesla Energy into Nvidia’s initiative to standardize cooling and power for AI data centers. Nvidia noted that escalating compute demand has heightened strains on electricity grids, power, cooling, water resources, and site locations.
Tesla Megapack Joins Nvidia’s DSX Ready Program
Nvidia reported that the DSX Ready framework debuted with cooling distribution units and battery energy storage systems. Qualified battery suppliers listed by the company include Tesla, Hitachi Energy, and LG Energy Solution.
LiquidStack, Vertiv, and LG Electronics earned qualifications for their cooling distribution units. Additional software and infrastructure categories will roll out over time, according to Nvidia.
For battery providers, Nvidia mandates that partners complete qualification testing and provide supporting data for evaluation. This review assesses products within designated technical parameters rather than granting approval to an entire data center location.
Nvidia’s DSX guidelines specify that battery evaluations focus on grid-adaptive power conversion performance. Testing parameters encompass dynamic power response, low-voltage ride-through, islanded operation, and current limiting.
Assessments additionally review black-start capabilities alongside transitions between islanded and grid-connected states. Nvidia requests technical models, control data, and telemetry to support these evaluations.
Nevertheless, Nvidia clarified that clearing this review does not guarantee site-level stability. Project developers must still independently evaluate switchgear, transformers, backup generators, and other infrastructure unique to each site.
Tesla Megapack Qualification Focuses on Power Conversion
This distinction limits what the DSX Ready designation implies for Tesla Megapack deployments. While qualification integrates the product into Nvidia’s component ecosystem, project engineers maintain full responsibility for site-level design.
Nvidia expects battery vendors to demonstrate compliance with multiple industrial standards. Its evaluation checklist points to frameworks from IEC, IEEE, UL, NFPA, and cybersecurity authorities.
Additionally, the company demands raw time-series metrics, testing configurations, and summary plots. Partners must supply pass-or-fail declarations tied directly to Nvidia’s specific technical metrics.
Tesla sells the Megapack as a utility-scale storage system that combines thermal systems, inverters, and battery modules. The current ordering platform features four-hour and two-hour setups.
The two-hour option is rated at 1,927 kilowatts and 3,854 kilowatt-hours, while the four-hour configuration delivers 979 kilowatts and 3,916 kilowatt-hours according to Tesla’s specifications.
Tesla also designates data centers as an appropriate application for the Megapack, noting the system can maintain uninterrupted operations during power outages.
Tesla Megapack Adds Another Data-Center Channel
This Nvidia qualification comes alongside continued growth in Tesla’s energy-storage division. Tesla documented 13.5 gigawatt-hours of energy storage installations over the course of the second quarter of 2026.
According to its second-quarter Form 10-Q filing, cumulative installations reached 22.3 gigawatt-hours through June. Revenue tied to energy generation and storage climbed 13% year over year during the quarter.
Tesla pointed to increased Megapack installations as the primary driver for this revenue growth, though lower average selling prices slightly offset the gains.
Tesla manufactures Megapacks at facilities located in Shanghai and California. The company’s 2025 annual report cited an installed production capacity of 40 gigawatt-hours at each site.
This manufacturing capacity supports Tesla’s broader strategy to scale stationary-storage output beyond its current facilities.
The DSX Ready status could open a fresh procurement pathway for Tesla within data-center projects built around Nvidia technology. However, Nvidia did not couple the qualification with any guaranteed Megapack purchase orders.
Nvidia Expands AI Factory Power Strategy
The introduction of DSX Ready aligns with Nvidia’s broader expansion into physical AI infrastructure, which increasingly ties processor deployment directly to data-center construction and electrical power availability.
In August, Nvidia unveiled an agreement with SB Energy centered on the PORTS-Pike Technology Campus located in Ohio. Nvidia stated that, with minor exceptions, the location will exclusively utilize its AI architecture.
The initial phase accounts for 4.25 gigawatts of IT load, alongside an option for an additional 3.75 gigawatts as the facility scales.
Nvidia noted that OpenAI is slated to operate out of the planned eight-gigawatt hub via long-term lease agreements, with initial capacity projected to come online in 2028.
In a separate SEC filing, SB Energy outlined an additional financial commitment from Nvidia, which agreed to purchase $1.5 billion in newly issued non-voting equity securities.
Although this financial investment remains separate from the Tesla Megapack qualification, both moves highlight Nvidia’s strategy to tackle grid constraints alongside processor supply.
For Tesla, DSX Ready increases the visibility and eligibility of the Megapack within Nvidia’s reference architecture, though deployment contracts are not guaranteed and builders must still complete site engineering before choosing equipment.
The next step for Nvidia involves scaling DSX Ready to encompass additional infrastructure sectors. Nvidia indicated these categories will launch gradually without providing a specific timeline.
