SAV Digital Power proudly presents the STORAGE KING — S2, a next-generation, high-efficiency energy storage cabinet purpose-built for commercial and industrial energy storage applications. With a system efficiency of up to 92.9%, it sets a new performance benchmark among similar products, proving that high efficiency truly equals high returns.

As the “carbon peaking and carbon neutrality” goals take deeper root, more and more businesses are turning to energy storage to cut electricity costs and stabilize power supply. However, this trend brings its own challenges: high summer temperatures reduce equipment efficiency; limited space makes large storage systems impractical; and strict safety demands mean any risk can lead to costly consequences.

Having specialized in commercial and industrial energy storage for years, SAV Digital Power understands what businesses truly need: higher efficiency, smaller footprint, and robust safety. To meet these needs, we developed the all-new STORAGE KING — S2. This powerful solution integrates dual-mode intelligent cooling, stacked solar-storage, and multi-level protection into a single cabinet — maximizing benefits in minimal space and helping businesses turn high efficiency into real profit.

01 Dual-Mode Cooling for Maximum Efficiency

No matter the ambient temperature, the STORAGE KING — S2 uses smart, multi-mode thermal management to stay efficient and reliable, ensuring higher yields and steadier returns.

♻️ Low Temperature: Zero-refrigerant natural air cooling — ultra-low energy consumption.
The air cooling module uses ambient air for natural cooling, minimizing power use.

♻️ Normal Temperature: Hybrid air-liquid cooling — smart adaptive mode.
A combination of natural airflow and low-power liquid cooling maintains optimal operating conditions at all times.

♻️ High Temperature: Powerful liquid cooling — stable even in extreme heat.
The liquid cooling module rapidly stabilizes battery temperatures, ensuring consistent, high-efficiency operation even under intense heat.

02 Stacked Solar-Storage for High Energy Density

♻️ Stacked Solar-Storage: Solar integration cuts consumption and boosts returns.
Integrated solar-storage technology allows direct storage of generated solar power, creating continuous revenue streams. The stacked design uses an all-in-one bracket structure for shading and energy savings — no civil works, no complex installation — delivering hassle-free efficiency upgrades.

♻️ High Energy Density: Just 1.323㎡ footprint, highly flexible deployment.
Each cabinet covers only 1.323㎡ — 16% less space than conventional solutions — delivering the industry’s highest energy density. Supports three-sided parallel installation to fit diverse sites and reduce delivery costs.

03 Multi-Level Protection for Ultimate Safety

Multiple advanced safety technologies combined with intelligent monitoring ensure worry-free operation and peace of mind.

♻️ Full-Range Detection & Active Fire Suppression: Reliable multi-layer protection.
Equipped with temperature sensors, smoke detectors, and aerosol fire extinguishers for layered monitoring and rapid fire response — any anomaly triggers immediate action.

♻️ End-to-End Stability: Cell-level monitoring, liquid cooling loop, IP67 protection.
Each battery cell is independently monitored in real time. Low-resistance liquid cooling ensures efficient heat distribution, while each module reaches IP67 rating for superior water and dust resistance — safe and reliable under all conditions.

STORAGE KING — S2: Maximum Efficiency, Total Peace of Mind

From smart cooling and compact integration to all-scenario safety, the STORAGE KING — S2 turns every kilowatt-hour into secure, stable, and profitable energy — empowering businesses with worry-free, cost-effective power management.
