From June 11 to 13, 2025, the 18th SNEC PV+ 2025 was grandly held at the National Exhibition and Convention Center in Shanghai. At this globally influential renewable energy event, SAJ showcased its comprehensive portfolio of Smart Energy Solutions, spanning residential to commercial and industrial (C&I) applications. The spotlight was on the launch of the next-generation AI Saving 2.0 — part of the SAJ‘s elekeeper EMS — demonstrating SAJ’s strong capabilities in AI-driven energy management, integrated system design, and full-scenario adaptability.
Driven by technological innovation, SAJ continues to deepen its presence in the smart energy sector, aiming to deliver more efficient, safer, and sustainable solutions for global users, and to accelerate the industry’s transition toward intelligence and low-carbon development.
At the exhibition, SAJ officially unveiled AI Saving 2.0, a major upgrade to its smart energy management engine. Unlike its predecessor, which functioned as a single algorithm module, AI Saving 2.0 integrates four self-developed algorithms: solar generation forecasting, load forecasting, electricity price prediction, and intelligent scheduling.
This intelligent engine enables seamless coordination between generation, storage, consumption, and electricity market strategies. It adapts dynamically to diverse regions and application scenarios, marking a breakthrough from passive response to proactive decision-making.
The system offers three intelligent operation modes—“Maximize Profit,” “Balanced Strategy,” and “Self-Consumption Priority”—allowing users to switch flexibly and customize energy strategies based on their specific needs. Moreover, AI Saving 2.0 is designed to seamlessly interface with Virtual Power Plant (VPP) platforms, automatically switching into VPP mode to enable higher-efficiency energy coordination.
One of the most notable upgrades is the introduction of a visual analytics engine, which clearly displays the logic behind scheduling decisions. Users can now intuitively understand why the system chooses to charge or discharge at a given time, based on forecasted data and user-defined preferences—breaking the “AI black box” and making energy management more transparent and reassuring.
SAJ first introduced AI Saving in 2023, becoming an early mover in the industry. Now with AI Saving 2.0, based on extensive global user feedback and continuous innovation, the system delivers even greater cost savings and market participation benefits. The new model offers enhanced accuracy and improved economic performance, particularly in scenarios such as negative electricity prices and time-of-use pricing.
Looking ahead, AI Saving 2.0 will continue to evolve. As algorithms grow smarter and user data scales up, it will become not only the “brain” of energy devices, but also a trusted partner in intelligent energy management.
During the exhibition, SAJ signed a strategic cooperation agreement with OSW, Australia's leading provider of clean energy solutions. The partnership focuses on deep collaboration in the Commercial and Industrial (C&I) energy storage sector, with an initial agreement totaling 200MWh—marking a significant step toward large-scale market deployment.
Leveraging SAJ’s strong technological foundation in smart energy storage and its professional after-sales capabilities, the partnership will deliver tailored energy solutions to Australian C&I users. Combined with OSW’s extensive local sales and service network, the two parties aim to improve energy efficiency and economic returns for businesses. Together, SAJ and OSW will promote Australia’s green energy transition through innovative storage technologies and a robust service ecosystem.
At the same time, SAJ has also reached cooperation agreements with several leading energy companies in Southeast Asia, including Brightfield Trading (Malaysia) and Bossway Solar (Philippines). By integrating local market resources and distribution channels, SAJ is accelerating the deployment of its smart PV & ESS solutions across the APAC region, expanding its global footprint and supporting the regional shift toward sustainable energy structures.
In a major move toward vertical integration, SAJ and EVE Energy announced a strategic collaboration for energy storage batteries, with a cooperation intention of up to 2GWh. A formal signing ceremony was held at the event.
This alliance combines SAJ’s expertise in energy storage system integration with EVE Energy's advanced battery cell technology, enabling high-performance batteries from EVE Energy to be widely used in SAJ’s storage products. The partnership will jointly deliver full-scenario smart energy solutions—from residential to C&I applications—injecting critical momentum into global energy transformation and carbon neutrality goals.
SAJ officially launched the “elekeeper Points Mall,” an installer points reward program for installation partners. Installers can accumulate points for every completed installation of SAJ products, which can be redeemed for a variety of complimentary products. This initiative not only deepens cooperation, but also encourages business development and builds a mutually beneficial ecosystem.
Installers also have access to the elekeeper One-click Diagnosis tool, which includes 7 diagnostic modules and over 20 detailed checks covering a wide range of scenarios. This allows them to quickly identify risks and improve installation efficiency, offering comprehensive technical support throughout the project lifecycle—from planning to service assurance.
As energy digitalization accelerates, SAJ is expanding its intelligent application portfolio, creating a unified energy management hub with capabilities in load forecasting, price-linked operations, and virtual power plant integration. Through end-to-end intelligent solutions, SAJ is refining its “product – service – ecosystem” value network, driving a digital and green transformation of global energy solutions.
SAJ’s CM2 series, the next-generation C&I smart energy storage system, is specifically designed to meet the complex energy demands of commercial and industrial applications. Featuring an all-in-one architecture, the system integrates high-performance PCS, EMS, and BMS in a single cabinet—boosting space utilization by 36%. Its plug-and-play multi-unit parallel design significantly reduces installation time and costs.
Built on a Five-layer Protection system, CM2 redefines safety standards. From AI-based cell-level monitoring to fire prevention measures within the battery cabinet, every detail is engineered for maximum safety. The system also leverages the AI-powered elekeeper- the smart energy management system, enabling in-depth interaction with power spot markets and supporting peak-valley arbitrage and VPP aggregation models. With intelligent control, users can increase overall energy yields by over 10%.
Through a Four-in-One system of solar-storage synergy, price arbitrage, grid frequency regulation, and virtual power plant aggregation, CM2 enables deep transformation toward zero-carbon, digital, and market-driven energy models, unlocking a new chapter in energy asset optimization.
The CHS2 series attracted significant attention at the SAJ booth, emerging as a highlight of the exhibition. As a benchmark in hybrid solar + storage solutions, CHS2 is designed to deliver exceptional performance in PV-storage integration.
