Driven by the “dual carbon” strategy, China’s energy storage industry is developing on a large scale. CNESA DataLink shows that by the end of 2024, China’s cumulative installed capacity of new energy storage reached 78.3GW/184.2GWh, with power and energy scales increasing year-on-year by 126.5% and 147.5% respectively. For the first time, it surpassed pumped storage to become the main force in power energy storage. In 2024, the newly commissioned scale was 43.7GW/109.8GWh, achieving triple growth for three consecutive years. In terms of policy, the “Action Plan for High-Quality Development of the New Energy Storage Manufacturing Industry” jointly issued by eight departments proposes achieving high-end, intelligent, and green development goals for the energy storage industry by 2027. With the dual driving forces of policy dividends and market demand, photovoltaic-storage integration has become the core direction for upgrading energy infrastructure.
However, behind the rapid expansion of the industry, homogenized competition has become a “sword of Damocles” restricting development. Currently, energy storage products in the market show high homogeneity in aspects such as capacity upgrade and liquid cooling technology application. Enterprises are trapped in a vicious cycle of “comparing capacities and competing on price.” Public data shows that in 2024, energy storage cell prices showed a clear downward trend, with the lowest transaction price falling below 0.3 yuan/Wh. Quotes from system integrators also dropped to 0.5-0.6 yuan/Wh. This homogenization dilemma not only compresses industry profit margins but also fails to meet terminal user needs precisely. Pain points such as high electricity bills, fragmented energy management, and poor equipment compatibility have long persisted.
Breaking the Deadlock: Zero-Code Architecture Reshapes the New Paradigm of Energy Storage Product Development
Faced with industry-wide challenges, Qualtech, with its independently developed 4S+C Zero-Code Architecture Platform at the core, has created an innovative integrated photovoltaic-storage solution. Through three core technological breakthroughs—zero-code integration of equipment protocols, zero-code configuration of process strategies, and unified management of multi-project code—the platform breaks free from the constraints of traditional development models.
A Revolution in Equipment Protocol Integration Efficiency
Under the traditional model, developers need 2-3 weeks to develop a single equipment protocol. The code has poor versatility and high maintenance costs. Qualtech has introduced Domain-Driven Design (DDD) thinking, abstracting mainstream protocols such as Modbus, CAN, and IEC 60870-5-104 into standardized models. With this approach, operation and maintenance personnel can complete protocol point table imports in just 0.5-1 days, achieving seamless integration of energy storage, photovoltaic inverters, liquid cooling systems, and other third-party equipment.
Flexible Customization of Process Strategies
To meet differentiated project requirements such as liquid cooling strategies and PCS control logic, Qualtech enables visual configuration of EMS/BMS processes through an automaton model. Without code development, users can independently define charge/discharge logic and multi-device coordination strategies. The function delivery cycle has been reduced from 1-2 weeks to within 1 day, with zero bugs and rework throughout the process.
Unified Management of Multi-Project Code
Traditional enterprises need to maintain hundreds or even thousands of project codes. Qualtech’s Zero-Code Architecture allows hundreds of projects to share a single code, significantly reducing version management complexity. It also supports hot standby switching between cloud and local modes, with system reliability improved by over five times compared to traditional solutions.
Integrated Photovoltaic-Storage System: The “Super Brain” of Energy Management Driven by Zero-Code Architecture
Based on the Zero-Code Architecture, Qualtech’s integrated photovoltaic-storage system integrates three functional modules: photovoltaic power generation, energy storage, and charging. It builds a closed-loop ecosystem of “power generation-storage-consumption” and offers the following core advantages:
All-Scenario Adaptability Design
* Standalone Mode: Supports 2-3 photovoltaic inputs, with a battery voltage range of 680-1000V. It can quickly switch between grid-connected and off-grid modes, making it suitable for backup power scenarios in remote areas. The off-grid switching time is ≤20 seconds.
* Multi-Machine Parallel Operation: Through a multi-level parallel system, power can be flexibly expanded to meet large-capacity power needs in factories and parks. In typical projects, the green electricity self-sufficiency rate can reach over 85%, supporting the construction of zero-carbon parks.
Intelligent Energy Scheduling System
* Priority to Photovoltaic Power Generation: In grid-connected mode, photovoltaic power is dynamically allocated to prioritize load requirements. Excess power is automatically stored in the energy storage system, significantly improving local consumption efficiency of green electricity compared to traditional solutions.
* Peak-Valley Arbitrage Optimization: By combining real-time electricity price data, the system automatically charges during off-peak hours and discharges during peak hours. This helps users reduce comprehensive electricity costs by 30%-40% (based on typical peak-valley price difference scenarios for industrial and commercial users).
Extreme Safety and Reliability
* Modular Liquid Cooling Design: Battery Packs are equipped with built-in fire protection systems, using IP54-rated enclosures. Combined with intelligent temperature control algorithms, the system ensures that cell temperature differences are controlled within ±2℃, extending battery cycle life by approximately 20%.
* Digital Twin Operations and Maintenance: Through a smart cloud platform, EMS/BMS/PCS are monitored in one go. With AI fault diagnosis technology, over 90% of potential equipment abnormalities can be identified in advance, increasing maintenance response speed by 60%.
Zero-Code Architecture is driving a transformation of energy storage products from “standardization” to “scenario-based customization.” CNESA predicts that by 2030, China’s cumulative installed capacity of new energy storage will reach 313.9GW (under an ideal scenario). Enterprises with rapid customization capabilities will gain a competitive edge in the market.
As an industry pioneer, Qualtech is optimizing development processes and enhancing solution adaptability through Zero-Code technology, providing a differentiated development path for the energy storage industry. This technological innovation significantly improves the matching efficiency between energy storage products and diverse scenario requirements. With its efficient and flexible development characteristics, it propels the energy storage industry toward intelligent and precise development.
With the deepening integration of Zero-Code technology and the energy storage field, Qualtech will continue to drive innovation. It will deepen the implementation of scenario-based solutions, offering more possibilities for the upgrading of the energy storage industry in global energy transformation and accelerating the achievement of green and low-carbon goals.
