BIPV is a building-integrated photovoltaic power generation system. Different from the traditional photovoltaic system installed on the roof or ground, BIPV integrates solar cell modules directly into the structure of the building, such as the roof, curtain wall, windows, sunshades, etc., so that it has both power generation function and architectural aesthetic characteristics.

In short, BIPV is not only a power generation system, but also a part of building design.

• Material-level integration: BIPV components must meet the specifications of building mechanics, fire protection, waterproofing, etc. For example, the use of 1156mm wide aluminum-zinc-magnesium trapezoidal tiles and 1134mm wide photovoltaic components without rail fixing technology, through hidden screws and waterproof gaskets to achieve zero roof seepage, wind resistance of 376 kg, and life span of the same frequency as the building.
• Photoelectric conversion path: Monocrystalline silicon cells (efficiency 22%-25%) and cadmium telluride thin-film cells (strong response to weak light) are combined according to the scene to achieve an adjustable light transmittance of 10%-50% for the building facade. The four-way ventilation design under the components improves the power generation efficiency by 8%-12% compared with the traditional BAPV system.
• System architecture: The grid-connected BIPV system consists of photovoltaic modules, combiner boxes, high-frequency inverters, energy storage batteries and smart meters. Among them, the high-frequency inverter converts direct current into pure sine wave alternating current to achieve grid parallel or off-grid switching.

2. Core features of BIPV system

• Versatility

BIPV components are not only used to generate electricity, but also undertake the functions of traditional building materials, such as heat insulation, sun shading, lighting, waterproofing, etc.

1. Working Principle of PCS

PCS is a key device in the energy storage system, which is mainly responsible for converting electrical energy from one form to another to meet different application requirements. In the energy storage system, PCS is usually responsible for converting alternating current (AC) in the grid into direct current (DC) to charge the energy storage battery; at the same time, when discharge is required, it converts DC back to AC to supply the grid or users.

The working principle of PCS involves power electronics technology and control strategy. Its core components include rectifier, inverter and control system. The rectifier is responsible for converting AC to DC, while the inverter is responsible for converting DC back to AC. The control system is responsible for monitoring the operating status of the entire system and adjusting the conversion efficiency of electrical energy according to demand.

PCS usually consists of the following core parts:

• Inverter module: responsible for converting DC power (from batteries or photovoltaics) into AC power;
• Rectifier module: converts AC power into DC power for charging the battery;
• Control unit: realize intelligent control of charging and discharging strategies, grid-connected parameters, and protection mechanisms;
• Filtering and isolation device: ensure that the output power quality meets the grid standards.

Through the collaborative work of these modules, PCS can flexibly control the charging and discharging behavior of the energy storage system based on factors such as the user's electricity demand, electricity price period, and grid status.

2. Core functions of energy storage converter

In energy storage systems, electric vehicles and various portable electronic devices, lithium batteries are widely used due to their high energy density, long cycle life and excellent safety performance. However, for ordinary users, some technical parameters of lithium batteries are still relatively unfamiliar, among which **discharge rate** is an often overlooked but very critical performance indicator.

This article will analyze what the discharge rate of lithium batteries is from a professional perspective, and combined with GreenMore's product practice, help you better understand its practical significance for home energy storage systems and commercial energy storage cabinets.

1. What is the discharge rate of lithium batteries?

The discharge rate (usually represented by "C") refers to the ability of a battery to complete discharge within a certain period of time and is one of the important parameters for measuring the battery's output power capability.

In simple terms:

• 1C discharge: means the battery can release its full capacity in 1 hour.
• 2C discharge: It means that the battery can release its entire capacity within 0.5 hours, which means the discharge speed is faster.
• 0.5C discharge: means the battery takes 2 hours to be fully discharged.

For example, if a lithium battery with a nominal capacity of 10kWh is discharged at a rate of 1C, its output power is 10kW; if it is discharged at a rate of 2C, the output power can reach 20kW.

2. The significance of discharge rate to energy storage system

• Impact on load responsiveness

The higher the discharge rate, the greater the power the battery can provide in a short period of time, making it suitable for driving high-power appliances such as air conditioners, water heaters, and water pumps. This is particularly important for household emergency power supply or commercial power peak regulation.

• Determine the system transient response performance

In the event of a grid failure or sudden load change, batteries with high discharge rates can respond quickly, provide stable power support, and ensure the continuous operation of critical equipment.

• Impact on system design and configuration

Selecting battery modules with appropriate discharge rates helps optimize the power configuration of the entire energy storage system and avoid problems such as "a small horse pulling a big cart" or "over-configuration".

3. Discharge rate requirements in different application scenarios

GreenMore's home and commercial energy storage product lines all use high-performance lithium iron phosphate (LiFePO₄) batteries, with differentiated designs based on different application requirements to ensure efficient and safe operation under various discharge conditions.

4. How does GreenMore optimize discharge rate performance?

As a professional energy storage solution provider, GreenMore has taken a number of key technical measures to improve the discharge rate of lithium batteries:

• Using high-quality battery materials

We use lithium iron phosphate batteries with excellent conductivity and thermal stability to ensure that they can maintain a stable voltage platform and low temperature rise under high-rate discharge.

• Intelligent BMS management system

Each GreenMore energy storage module is equipped with an advanced battery management system (BMS) that monitors discharge current, temperature and SOC (state of charge) in real time to prevent overload, overcurrent and abnormal heating, ensuring safe operation of the system.

• Structural heat dissipation optimization design

By optimizing the internal structure and heat dissipation channels of the battery module, heat accumulation during high-rate discharge can be effectively reduced and the service life can be extended.

• Multi-module parallel technology

In commercial energy storage cabinets, GreenMore adopts a multi-module parallel architecture, which can flexibly adjust the total output power to meet high-rate discharge requirements while improving system redundancy and reliability.

5. How to choose the appropriate discharge rate according to needs?

When purchasing a home or commercial energy storage system, it is recommended to evaluate the required discharge rate from the following aspects:

• Average daily electricity consumption and peak power demand of households/businesses
• Whether off-grid operation or emergency power supply is required
• Whether to participate in grid frequency regulation or demand response services
• Are there high-power electrical appliances that are frequently started and stopped

If you are not sure about your specific needs, you can contact GreenMore's professional technical team. We will recommend the most suitable energy storage solution based on your actual electricity usage.

6. Is the higher the discharge rate, the better?

This is a common misconception: not all applications are suitable for using batteries with high discharge rates.

Advantages of high discharge rate:

• Rapid release of large amounts of energy to meet high power demands
• Fast response, suitable for emergency power supply scenarios
• Improve system dynamic performance, suitable for commercial frequency modulation

Potential problems with excessive discharge rate:

• Increased heat generation: High rate discharge will cause internal temperature rise, affecting battery life
• Rising costs: High-rate battery manufacturing processes are more complex and more expensive
• Decreased energy efficiency: Some batteries lose efficiency at high rates, resulting in energy waste
• Safety risks: Without a good BMS protection mechanism, it may cause problems such as overcurrent and thermal runaway

Therefore, in practical applications, the discharge rate should be reasonably selected according to the specific usage scenario, load type, and system design goals, rather than blindly pursuing "the higher the better".

Conclusion

The discharge rate of lithium batteries is one of the key parameters to measure their output capacity and application range. It not only affects the performance of the energy storage system, but also directly affects the user experience and return on investment.
