Risen Stack1: The Power of Efficient Backup——Technical Insights Series ①

As the demand for clean and reliable power grows, energy storage systems must be more than functional—they must be flexible, efficient, and intelligent. The Risen Stack1 modular storage system is designed to meet these needs, offering high-capacity output, smart scheduling, and 24/7 backup. In this Q&A, we explore how it delivers reliable power in complex scenarios—from structural design to energy management and power quality.

48–120 kWh a single device – flexible capacity, for both C&I and resident

Q1: How does the modular stacking system recognize capacity and seamlessly adapt to different configurations?

A: Risen Stack1 uses a DCDC + PCS dual-topology architecture. The DCDC (a DC-DC converter that adapts voltage levels across modules) accommodates voltages from 150V to 1,000V, enabling stable adaptation and efficient conversion across varying modular setups. The system also includes automatic capacity recognition, which reads the number of battery packs and calculates total capacity, allowing for flexible expansion without the need for extra configuration.

60 kW high power – true all-scenario power supply

Q2: Does the 60kW output fluctuate under peak loads or simultaneous multi-device use, and how is power quality maintained?

A: In grid-connected mode, Risen Stack1 can output reactive power to stabilize grid voltage, maintaining power quality even when the external grid is unstable. In off-grid mode, the system independently generates voltage and frequency to support smooth multi-device operation.

Q3: What PCS topology supports sustained 60kW output and unbalanced loads?

A: The system adopts a three-level topology PCS. Unlike traditional two-level inverters, which directly convert DC to AC and result in higher harmonic distortion, the three-level design introduces a zero-voltage level, producing waveforms closer to a pure sine wave. This reduces switching loss and improves power quality. It also lowers the voltage stress on switching components, reducing heat and supporting unbalanced load operations.

Multi-Mode Operation for Broad Scenario Adaptation

Q4: What are the strategies behind the four operating modes of the system?

A: Users can manually switch between modes based on their electricity usage patterns.

• Custom Mode: Customize time-based usage to align with consumption habits

• Green Power Mode: Prioritize clean energy by coordinating PV inverters and battery storage

• AI Mode: Leverages big data to analyze user behavior, electricity tariffs, and PV forecasts, then selects the optimal dispatch strategy

• Remote Dispatch Mode: Allows third-party EMS to manage system scheduling

Daytime charging, nighttime use – 24/7 backup

Q5: How does the system determine charge/discharge timing and enable adaptive dispatch?

A: Based on historical usage data and PV forecasts, Risen Stack1 optimizes its charge/discharge plan. In Green Power Mode, excess solar power is stored for later use. In Clock Mode, users can configure up to 12 charging/discharging periods, enhancing economic efficiency.

Q6: How does the system protect battery life during long-term“charge-by-day, discharge-by-night” use?

A: The intelligent BMS continuously monitors battery status and enforces strict voltage limits to prevent overcharging and deep discharging, both of which can degrade battery life.

Q7: How does the system optimize day charging and night discharging based on regional climate and sunlight conditions?

A: By integrating a power generation forecasting mechanism based on meteorological data, users can plan energy storage and usage more effectively according to local climate and consumption patterns.

Q8: Can the system prioritize critical loads, and can users customize device priorities?

A: With the energy controller, Risen Stack1 supports both power supply and generation inputs including PV, storage, gensets, and the grid. Loads can be categorized by priority (e.g., Tier 1/Tier 2), and with the optional STS unit, users can achieve seamless grid/off-grid switching and ensure uninterrupted power to critical equipment.

From flexible stacking and adaptive capacity, to stable 60 kW output and intelligent multi-mode scheduling, Risen Stack1 redefines a new standard for efficient backup power. It reflects Risen Energy’s strong R&D capabilities in storage architecture and system integration.
