PREFACE
Residential energy storage systems have become a key component of household electricity solutions under the broader context of the global energy transition. As the energy storage market matures, residential storage investors are increasingly concerned about how to use electricity cost more economically through energy storage systems. With the evolving electricity market structures and retail electricity models across different countries, residential storage devices can enhance investor returns by improving product performance and operational efficiency. As lithium-ion battery prices continue to decline, the economics of end-user storage deployment have improved, driving greater interest in residential energy storage installations. However, the influx of substandard, low-cost products into the market has raised concerns. Rather than delivering cost savings, such products pose significant safety risks to end users.
Based on more than 15 years of experience in the global residential energy storage sector and a deep understanding of end-user needs, Pylontech has developed the “Profit and Performance Residential Energy Storage System Solution White Paper.” This white paper addresses key concerns related to economic return, safety, efficiency and proposes practical solutions for enhancing the economic value of electricity consumption through improved product performance and system efficiency. It aims to support end users, electricity retailers, and channel partners in making more balanced and informed investment decisions.
Application Scenarios: Case Studies
With the transformation of the global energy mix and the rapid development of renewable energy sources, the economic benefits of energy storage systems in residential energy management have become increasingly prominent. The rising frequency of extreme weather events, persistent energy price volatility, and growing electricity demand are introducing new risks and challenges to the stability of household power supply. Residential energy storage systems offer flexible and efficient energy solutions—by storing solar energy generated during the day or electricity from off-peak periods, home users can utilize stored power during peak demand hours, thereby reducing electricity costs. At the same time, these systems increase energy self-sufficiency, reduce dependence on the external grid, and enhance households' resilience to energy market fluctuations.
Moreover, with the advancement of energy storage technology and cost reduction, the payback period for residential energy storage investments is becoming increasingly attractive. More and more households are recognizing energy storage as a viable means of achieving long-term cost savings. Driven by supportive policies and strong market demand, residential storage systems are becoming an important part of modern household energy management—supporting sustainable development goals and accelerating the transition toward a green economy.The following two case studies illustrate how residential energy storage systems are helping families around the world to reduce electricity expenses and secure reliable power supply.
1.1 Case 1: Household Electricity Bill of Caroline
Caroline lives in the Main-Spessart region of Germany. She owns an electric vehicle and a heat pump. As a typical family of four, their annual electricity consumption is approximately 10,560 kWh. Currently, Caroline is on a fixed-rate electricity tariff provided by a local energy retailer, with an average electricity cost of around €350 per MWh, resulting in an annual electricity bill of approximately €3,844. For Caroline, electricity expenses represent a significant financial burden. So, what can be done to reduce this cost? In the context of the global energy transition and continued decline in photovoltaic (PV) module prices, installing a PV system appears to be a straightforward and effective solution.
If Caroline installs a 10 kW rooftop solar system, it could generate approximately 9,000 kWh of electricity per year. This figure sounds promising—potentially enough to offset nearly all of her household's annual electricity demand. However, PV generation is inherently intermittent—it only produces electricity when the sun is shining. As a result, when the timing of electricity consumption does not align with solar production, a considerable portion of the generated energy cannot be effectively utilized. In practice, the 10 kW PV system would reduce Caroline's annual electricity bill by only about €1,100. To unlock the full potential of her solar investment, Caroline chose to install a residential battery storage system alongside the PV system. This enables her to store excess solar energy generated during the day and use it during peak demand hours or at night—significantly increasing the utilization rate of her solar power and further enhancing the system's economic value.
Electricity Tariffs in Different Modes(€)
In Germany, residential PV systems with self-consumption capabilities are also eligible for feed-in tariff (FIT) incentives. When Caroline opted for a self-consumption model supported by a 10 kW PV system paired with a 15 kWh residential battery, not only was her household electricity demand effectively met—leading to significant bill savings—but she also benefited from selling surplus electricity back to the grid. With this setup, her annual electricity expenses could be reduced to approximately €1,530, representing an additional savings of €1,201 per year compared to using PV alone. At the same time, the local utility company introduced dynamic electricity pricing contracts. Under this pricing structure, the electricity price is lowest during the midday period—when solar generation peaks—and highest in the evening, when PV output drops to zero. As a result, the income from selling excess solar energy during low-price periods is significantly diminished. This led Caroline to consider a new question: under a dynamic pricing model, could she store excess solar electricity in the battery and then discharge it back to the grid during peak price periods to maximize revenue? For Caroline, the ideal storage solution would include a smart energy management system capable of actively tracking real-time electricity prices and intelligently adjusting the battery's charge and discharge strategy. This dynamic operation would enable her to optimize both cost savings and revenue from energy arbitrage, thereby maximizing the overall economic benefit of her residential energy storage system.

1.2 Case2: Typical Residential Storage in Sweden
In Sweden, installing a 7.5 kW/15 kWh residential photovoltaic (PV) plus energy storage system can qualify for a tax credit subsidy of up to 50% under the "Green Technic" policy, amounting to approximately €4,800 per person annually. Once you have a PV energy storage system, not only can it reduce your electricity bill, but in areas with Time of Use (TOU) electricity pricing, resident users can charge their battery during low-rate periods and discharge during peak hours to offset high electricity costs. By integrating an Energy Management System (EMS) to optimize local load and appliance operations, energy efficiency can be further improved, leading to additional bill savings. Moreover, in some regions, residents can allow utilities to access stored energy during peak demand periods and receive compensation. Similar programs are becoming increasingly widespread, providing additional revenue streams for residential energy storage systems, making ESS a more attractive investment.
Energy Storage System
After installing a 7.5 kW/15 kWh residential PV-plus-storage system, home users can further enhance system value by connecting to a Virtual Power Plant (VPP), particularly during high-demand events such as summer heatwaves. A VPP is a virtual aggregation of small-scale distributed energy resources (DERs), including solar PV, battery storage, EV chargers, as well as demand response-enabled devices like water heaters, heat pumps, and household appliances. VPP technology plays a critical role by supplying additional capacity during peak demand periods. These programs are designed to reduce stress on the grid and provide electricity to local California communities, helping to prevent power emergencies. Participants agree to allow their stored battery energy to be dispatched as part of a coordinated energy management plan and are compensated for their contributions.
The core of a VPP lies in its optimization algorithm. A sophisticated and accurate VPP algorithm analyzes real-time data and forecasts energy demand to determine how best to utilize available distributed resources. Therefore, responsive and precise hardware systems, advanced and flexible software platforms, and reliable, low-latency communication technologies are essential for VPP. These systems continuously monitor the performance and status of each DER, collecting critical data on energy generation, consumption, and storage levels. This real-time data enables the VPP to make intelligent decisions—balancing supply and demand, optimizing energy flows, and ensuring overall grid stability.
Critical Factors of Residential Energy Storage Systems
In line with energy storage market maturation, a clear trend has emerged: residential ESS investors are becoming increasingly concerned about whether the returns generated by their systems can offset the substantial upfront investment. While the economic benefits from PV and ESS are generally predictable, the evolving nature of electricity markets introduces significant uncertainty. Business models that tie revenue closely to market prices are increasingly exposed to volatility, and traditional forecasting models and trading strategies—largely reliant on historical data—are proving inadequate in this new environment. Under these conditions, further enhancing the economic value of ESS demands higher performance — specifically in terms of total throughput over the system's lifetime, intelligent dispatch capabilities, and reliable operation and maintenance (O&M) services.
2.1 System Efficiency and Cycle Life
To improve the total throughput per unit cost and enhance economic returns, energy storage systems must strike a balance between optimizing energy efficiency and maximizing the battery cycle life throughout the system's lifetime. This approach not only extends system longevity but also ensures long-term, stable financial returns.
ESS Total Throughput Over the System's Lifetime
Capacity for Any Number of Cycles
System Energy Ef ficiency
System energy efficiency, defined as the ratio of discharged energy to charged energy, is influenced by multiple interrelated factors, including accurate battery state estimation, thermal management, power conversion technology and etc. System energy efficiency obviously effect Levelized Cost of Energy (LCOE).
Accurate battery state estimation plays a foundational role. Reliable assessment of key parameters such as State of Charge (SoC) and State of Health (SoH) is critical for both safety and efficiency. Inaccurate estimations often force systems to operate within reduced depth-of-discharge (DoD) ranges, limiting usable capacity, lowering utilization, and increasing the risk of failure.
Battery Cycle Life
The number of effective charge/discharge cycles determines the duration of ongoing revenue. Improving cycle life requires the use of long-lasting battery cells, well-designed charge/discharge strategies, and optimized pack design to mitigate cell degradation and extend system durability.

2.2 Energy Management and Dispatch
Advanced technologies such as artificial intelligence and data analytics enable long-term health monitoring and predictive diagnostics, ensuring sustainable investment returns and maximizing asset value. This evolution places higher demands on energy management systems, algorithmic intelligence, and system integration capabilities.
Energy Management System (EMS)
The EMS is a critical component of any energy storage system, comprising both software and hardware used to monitor, control, analyze, and optimize energy flow and consumption in real-time. An effective EMS schedules charge and discharge operations intelligently. In the event of a grid disturbance, the system must respond to frequency and voltage fluctuations within milliseconds to stabilize grid operations. Therefore, intelligent dispatch strategies, millisecond-level device response, and extensive system validation are essential to ensure efficient energy utilization and reliable power supply.
Parallel Inverter Management
Parallel inverter management enables multiple hybrid inverters to work in coordination by connecting them on the AC side, enhancing overall storage and dispatch capabilities while improving system reliability and flexibility. This system plays an important role in the storage and management of renewable energy.
2.3 Operation and Maintenance
The operation and maintenance of residential energy storage play a crucial role in enhancing system efficiency, ensuring safety, and optimizing user experience. It is necessary to gradually improve the operational efficiency and user experience of home energy storage systems through simplified installation, remote support services, and data management.

Guided by a customer-centric development approach, we have consistently focused on both profitability and performance. As a result, we have continued to developing advanced technologies and competitive product advantages. The following are three critical parts:
High Efficiency and Long Cycle Life
Intelligent Scheduling
Seamless Operation with Smart System Management
VERTICAL PRODUCTION CHAIN AND CORE
3.1 High Efficiency and Long Cycle Life: Significantly Reducing Levelized Cost of Energy (LCOE)
Accurate and reliable calculation of the battery's State of Charge (SOC) and State of Health (SOH) is the foundation for proper utilization of energy storage systems. Cell consistency plays a critical role in determining the system's capacity efficiency, safety, and ultimately its economic return. An effective and intelligent cell balancing strategy is key to maintaining cell consistency over time. Additionally, scientific cell design and manufacturing processes are essential for ensuring battery stability and longevity. Combined with refined structural design and robust early warning mechanisms, only a system that is comprehensively and scientifically engineered can achieve truly high efficiency and reliability.
3.1.1 High-Efficiency and Accurate BMS Design
In lithium iron phosphate (LFP) energy storage systems, algorithm performance is critical for both system optimization and operational safety. Algorithms related to State of Charge (SOC), State of Health (SOH), and cell balancing form the core of battery management system (BMS) functionality. These elements are foundational to maintaining long-term stability, safety, and performance across the entire energy storage lifecycle.
SOC Algorithm
The estimation of the State of Charge (SOC) is a critical function of the Battery Management System (BMS), as it reflects the remaining capacity of the battery. Accurate SOC estimation helps prevent overcharging and over-discharging, extends battery life, and optimizes energy management strategies. Due to the nonlinear voltage-SOC relationship of lithium iron phosphate (LFP) batteries—particularly within the mid-SOC range—traditional estimation methods often struggle to achieve high accuracy.
Pylontech employs a Double Sigma Point Kalman Filter (DSPKF) algorithm for SOC estimation in its LFP batteries. This advanced algorithm enhances accuracy when dealing with nonlinear systems and also provides excellent real-time performance and robustness. It continuously updates the SOC estimate by integrating
Key features of the algorithm include:
• Online parameter identification of the equivalent circuit model using dual Kalman filters, improving the accuracy of model parameters used in SOC estimation;
• Advanced filtering techniques that outperform conventional methods such as ampere-hour integration and extended Kalman filters in terms of estimation accuracy;
• Industry-leading accuracy, maintaining full-range SOC estimation error within 3%;
• Validation through DST (Dynamic Stress Test) conditions as defined in standard GB/T 38661. The new SOC algorithm was tested under continuous DST cycling and compared against the traditional Kalman filter method. Results are illustrated in the figure below (left).
Accuary of Dynamic Stress Test
SOC(%)
SOC Real New algorithm Normal algorithm
SOC Error(%) New algorithm Normal algorithm
As shown in the above (right) figure, the proposed new SOC algorithm demonstrates significantly improved accuracy, with estimation errors consistently maintained within a 3% margin.
SOH Algorithm
The State of Health (SOH) is directly related to the evaluation of battery condition and service life. It reflects the extent of capacity degradation compared to the battery's initial state. During long-term cycling, factors such as ambient temperature and usage patterns can introduce inconsistencies, thereby affecting the accuracy of SOH estimation.
For energy storage systems, obtaining a timely and accurate understanding of battery health is essential for fault prediction and preventive maintenance. Pylontech adopts the Two-Point Method for SOH estimation. This approach estimates battery health by calculating the actual discharge capacity between two SOC reference points. It is a simple and intuitive method—actual charge/discharge capacity is computed using ampere-hour counting. However, one of the key challenges in practice is acquiring accurate SOC reference points and maintaining estimation reliability. In this method, two SOC points are selected: one at full charge, and the other at rest after deep discharge. This approach effectively minimizes deviations caused by SOC estimation inaccuracies and improves capacity evaluation reliability.
Dynamic Stress Test
To verify the validity of the SOH algorithm, a long-term aged battery module was selected for testing. The actual capacity degradation observed during cycling was compared with the SOH estimation results to assess algorithm accuracy:
• As shown in the figure, a significantly aged module was chosen to validate SOH estimation effectiveness;
• The comparison between actual and estimated SOH values shows that the error remained within 2%.
Global Balancing Algorithm
Inherent differences among individual battery cells can lead to inconsistencies in voltage and capacity over extended use, ultimately impacting the performance and lifespan of the entire battery pack. As such, balancing algorithms play a crucial role, especially in lithium iron phosphate (LFP) energy storage systems, where global passive balancing strategies are widely adopted. Traditional voltage-based balancing logic is not fully suitable for LFP batteries, as the voltage difference between cells during the flat voltage plateau is minimal—even when there are significant capacity differences. This makes it difficult to trigger balancing based solely on voltage.
Pylontech adopts a balancing strategy based on available residual capacity. The objective is to ensure that all cells within a battery pack maintain consistent usable capacity levels. This approach effectively keeps the operational state of all cells aligned, enhancing overall system stability and performance. In large-scale battery systems, energy loss associated with passive balancing becomes a critical design challenge. Accurate calculation of balancing time requires high-precision SOC and SOH algorithms.
Pylontech's global balancing algorithm is built upon this foundation, with a framework that enables intelligent and effective balancing control:
Dynamic at low SOC
Resting state at low SOC
Determine the reference cell (internal resistance and capacitance are normal)
Charging terminal status
Dynamic in the platform area
Calculate balancing time remaining
Determine balancing enable flag bit
Execute the Balancing commands on eligible cells
Close the Balancing commands on Ineligible cells
The global balancing strategy offers the following advantages:
• Dual-factor evaluation using both cell SOC and voltage enables more accurate identification of cells requiring balancing. This reduces the risk of incorrect or ineffective balancing and minimizes the negative impact of over-balancing on cell lifespan.
• Compared to conventional voltage-based balancing, global balancing provides more frequent and flexible balancing opportunities for eligible cells, thereby improving both balancing efficiency and overall cell consistency.
• Unlike traditional voltage-based strategies, which typically activate balancing only at the end of discharge, Pylontech's global balancing approach improves balancing efficiency by over 60%.
• Following GB/T 38661 balancing test standards, experimental results confirm that the global balancing strategy delivers significantly improved balancing performance.

Cell Reliability Through Continuous Optimization
Cell cycle life is a key factor affecting the total energy throughput of a battery system. Pylontech has adopted a multi-pronged approach to enhance cell performance and extend cycle life:
Electrolyte Formulation Optimization
By precisely adjusting the type and concentration of electrolyte additives, the thickness and porosity of the solid electrolyte interphase (SEI) layers can be controlled. This improves lithium-ion transport, reduces interfacial resistance, enhances energy efficiency, and ultimately extends battery cycle life.
Crystal Structure Optimization of Active Materials
By controlling synthesis conditions, materials with smaller grain sizes or higher crystallinity can be produced. These structural improvements accelerate ion diffusion, increase charge/discharge capacity, and indirectly extend the battery's lifespan.
Use of Chemically Stable and High-Temperature-Resistant Materials
Selecting more stable materials—such as lithium iron phosphate (LFP) for the cathode—reduces the likelihood of side reactions during cycling. LFP cathodes degrade at a slower rate than graphite anodes, while NCM (nickel-cobalt-manganese) cathodes tend to degrade faster. As a result, LFP batteries generally offer longer cycle life compared to NCM lithium-ion batteries.
Material Processing Enhancements
Surface modification techniques and optimized sintering processes reduce surface area and structural defects, mitigating adverse reactions between the electrode material and electrolyte. This helps to further extend battery life.
The test results based on IEC 62620 show that after optimizing the electrolyte, the battery efficiency increased to 96.26%. The pre-lithiation technology can effectively improve the battery's cycle life by 4,000 cycles.

The pre-lithation method can increasethe numberofcycles by upto 4,000 cls.
3.2 Intelligent Scheduling for Enhanced Returns
3.2.1 Energy Management System
The Energy Management System (EMS) plays a pivotal role in intelligent scheduling, primarily in three key areas: optimizing energy management, enabling demand response and grid interaction, and improving energy utilization and economic returns.
Optimized Energy Management
EMS enables centralized scheduling and management of all energy storage units within a system, allowing for optimal allocation of energy resources. For example, when multiple storage units are managed under one EMS, the system can dynamically adjust the charge and discharge plans of each unit based on load demand, generation status, and electricity price signals—ensuring both efficient and cost-effective energy use.
Demand Response and Grid Interaction
EMS facilitates intelligent interaction with the power grid. It automatically adjusts the charge/discharge behavior of the storage system in response to grid conditions and price signals, allowing it to participate in demand response programs. During periods of grid stress or limited supply, EMS can help balance the load and relieve peak demand pressure.
Improved Energy Utilization and Economic Performance
Through smart scheduling and real-time optimization, EMS significantly reduces energy losses within the storage system and enhances overall storage efficiency. In electricity markets characterized by price volatility, EMS can further increase system profitability by identifying the most favorable time windows for charging and discharging based on real-time price forecasting.
Unlike traditional EMS, which relies on preset rules and static parameters, Pylontech's EMS-Agent offers adaptive and intelligent charge/discharge strategy adjustment. Leveraging AI technologies, the system analyzes historical load curves and localized electricity prices on the user side to automatically generate tailored demand management strategies. It supports multi-objective optimization, including revenue maximization under full-load scenarios, incremental return improvement, and risk-aware operational control—ensuring safe operation while extending system lifespan.
Improved Forecasting Accuracy
With the help of large-scale AI models, load forecasting accuracy is improved by 18%–25%, with forecasting errors reduced to below 5% during peak production periods.
Price Volatility Response
Based on accurate electricity price predictions, the EMS ensures the battery charges during low-price periods and discharges during peak pricing windows. When price fluctuation ranges between 15% and 20%, optimized scheduling can yield 12%–18% additional revenue.
Power Station State
3.2.2 Parallel Management Strategy
Hybrid inverters can be connected in parallel to achieve cumulative power output and energy storage capacity. Each inverter operates independently, and the total system output equals the combined capacity of all connected units. This architecture offers several key advantages:
Load Sharing and Energy Management
In a parallel system, hybrid inverters can intelligently share load and manage energy distribution. The master inverter utilizes advanced control algorithms to establish current circulation among units, enabling dynamic energy redistribution. This ensures that each inverter evenly shares the power load and storage responsibilities. The system is capable of maintaining the SOC difference between inverter battery clusters within 5%, thereby ensuring system stability and operational efficiency.
Redundancy and Reliability
Parallel operation introduces a layer of system redundancy. In the event of a failure in one inverter, the remaining inverters continue functioning normally, thereby improving the overall system reliability. This feature is especially critical in mission-critical applications where uninterrupted energy supply is essential.
Scalability
Parallel hybrid inverter systems are highly scalable. When additional power or storage capacity is required in the future, new units can be easily added to the system without major modifications, enabling flexible and rapid expansion.
