Amid the global energy transition, the demand for efficient and flexible energy solutions among households and small commercial users is growing rapidly. However, traditional photovoltaic (PV) energy storage systems often face numerous challenges in practical applications, such as low system efficiency, component degradation, unstable lighting conditions, and high system costs. To address these challenges, Hinen has launched the 5kW Single-Phase Hybrid All-in-One Residential Storage System H5S, which features an innovative 200% PV oversizing technology that brings users a brand-new energy management experience.
What is Oversizing?
Oversizing refers to a system design approach where the capacity of the PV modules exceeds the rated capacity of the inverter. Specifically, when the ratio of PV module power to the inverter's rated power (oversizing ratio) is greater than 1:1, it is considered oversizing. For example, the Hinen 5kW Single-Phase Hybrid All-in-One RESS H5S supports up to 10kW of PV input power, achieving an oversizing ratio of 2:1.
Why Oversize?
- Maximizing System Benefits In practical applications, PV systems are affected by factors such as component degradation, insufficient lighting, and line losses, resulting in lower power generation efficiency than theoretical values. By adopting an oversizing design, these losses can be effectively compensated, improving the overall power generation efficiency and return on investment of the system.
- Adapting to Complex Environmental Conditions Lighting conditions vary significantly across different regions. An oversizing design allows the inverter to maintain a higher output power even in low-light conditions, extending the full-load operating time.
- Reducing System Costs A well-designed oversizing approach can reduce system construction and maintenance costs by decreasing the number of inverters needed and optimizing system configuration.
Advantages of Hinen 5kW Single-Phase Hybrid All-in-One RESS H5S with 200% PV Oversizing
The Hinen H5S All-in-One Machine adopts 200% PV oversizing technology, supporting up to 10kW of PV input power, far exceeding its rated output power of 5kW. This design not only maximizes the use of solar energy but also enhances the user experience in the following ways:
- Efficient Energy Management The H5S is equipped with advanced MPPT algorithms that accurately track the maximum power point of PV modules, ensuring the highest efficiency of energy conversion under different lighting conditions.
- Flexible System Configuration Users can flexibly configure the number of PV modules according to their needs, maximizing the use of roof space while ensuring the system operates efficiently in different seasons and weather conditions.
- Smart Monitoring and Management The H5S is equipped with a cloud monitoring platform that allows users to monitor the system's operating status, power generation, and energy storage in real-time via the Hinen APP, achieving intelligent energy management.
- Safe and Reliable Energy Storage Solution The H5S uses high-performance lithium iron phosphate batteries, which offer long life, high safety, and stable charging and discharging performance. The built-in BMS (Battery Management System) continuously monitors the battery status to ensure safe system operation.
Application Scenarios: Meeting Diverse Market Needs
- High-Tariff Regions By adopting the "self-generation and self-use + surplus power to the grid" model, users can reduce dependence on the grid and mitigate risks from tariff fluctuations. With 200% oversizing, even in winter or cloudy days, the system can maintain a high self-use rate.
- Areas with Unstable Grids The off-grid/on-grid seamless switching function ensures continuous household electricity supply, minimizing losses caused by power outages.
- Policy-Incentivized Markets Certified with multiple international standards such as CB/CE/UKCA, the H5S offers a 10-year warranty, meeting local grid-connection and subsidy application requirements to accelerate investment returns.
