It integrates power generation, conversion, storage, and consumption into one, making it suitable for large residences, shopping complexes, farms, and small factories.
CHS2 supports self-consumption, time-of-use pricing, and backup power applications, and can be easily integrated with diesel generators or other auxiliary devices to ensure stable and reliable power supply. With its all-in-one design , on-site commissioning is fast and simple, greatly improving installation efficiency and user experience.
-
CM2 Smart C&I All-in-One BESS
The CM2 Smart C&I All-in-One BESS is designed for diverse C&I applications. It offers outstanding energy efficiency and flexible capacity expansion, supporting multi-unit parallel connections to meet growing power demands. Its modular design simplifies installation and commissioning, saving users both time and cost.
Equipped with intelligent battery monitoring and multiple fire protection mechanisms, the system ensures safe and stable operation. Cluster-level management effectively isolates faults, ensuring system continuity . Combined with the SAJ's smart energy management platform-elekeeper, it enables peak-valley electricity arbitrage and VPP aggregation, helping users optimize energy strategies and maximize economic returns.
-
HS3 All-in-One System
This smart integrated residential energy solution combines PV inverter, EV charger, storage inverter, battery, backup power, and EMS into a single compact unit. With a body thickness of just 17 cm, it is ultra-thin, space-saving, and elegantly designed to blend into various home environments.
It features millisecond-level switching to ensure uninterrupted household power supply. Powered by the advanced AI Saving 2.0 algorithm, the system intelligently matches load demand with PV generation, optimizing charge/discharge strategies for whole-home energy management. This significantly reduces electricity costs and supports green low-carbon living—making it an ideal choice for the future smart home energy hub.
-
AI Saving 2.0
As the core upgrade of SAJ’s EMS, AI Saving 2.0 introduces a multi-dimensional self-developed AI decision engine, integrating four core algorithms: generation forecasting, load forecasting, electricity price forecasting, and intelligent scheduling.
It offers three flexible operation modes: “Maximized Profit,” “Balanced Return,” and “Self-Consumption Priority,” to meet different user needs. Through real-time data analysis and dynamic scheduling, it optimizes energy flow to lower costs and improve ROI. AI Saving 2.0 also supports seamless Virtual Power Plant (VPP) integration, enabling collaborative energy sharing and market participation across multiple users. This elevates energy management intelligence while providing more efficient, economical, and sustainable energy use.
