In a solar photovoltaic system, the inverter plays a vital role. It is responsible for converting the direct current (DC) generated by the photovoltaic panels into alternating current (AC) for home and commercial use. According to their operating frequencies, inverters are mainly divided into high-frequency inverters and low-frequency inverters. This article will introduce the characteristics, advantages and applicable scenarios of low-frequency solar inverters in detail from the professional perspective of GreenMore.

1. Working principle of low frequency solar inverter

Low-frequency solar inverters use power frequency transformers to convert direct current (DC) to alternating current (AC), and their core operating frequency is 50Hz or 60Hz. Compared with high-frequency inverters, low-frequency solutions use the principle of electromagnetic induction to achieve voltage amplitude adjustment and electrical isolation through transformer windings. This design retains the stability advantage of traditional power frequency transformers, while reducing harmonic interference by optimizing the filter circuit, and the output waveform is closer to a standard sine wave.

At the structural level, low-frequency inverters usually include DC input, full-bridge inverter circuit, power frequency transformer, filter circuit and control module. Among them, the power frequency transformer, as a key component, undertakes the dual functions of voltage conversion and safety isolation. Its core material is made of high-permeability silicon steel sheets to effectively reduce hysteresis loss and eddy current loss.

Key features of low frequency inverter:

• High power output: Low frequency inverters are able to handle higher power loads due to the use of conventional oversized transformers.
• Better shock resistance: suitable for starting equipment that requires instantaneous high power, such as motors, refrigerators, etc.
• More stable performance: It has stronger adaptability to power grid fluctuations, especially excellent performance in harsh environments.

2. Advantages of Low Frequency Solar Inverter

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.

With the rise of global energy prices and the enhancement of environmental awareness, more and more families are beginning to pay attention to solar power generation systems, hoping to reduce electricity bills and achieve green and low-carbon life by installing photovoltaic equipment. However, many users face a core question when planning a home photovoltaic project: How big a solar system do I need for my home?

As a manufacturer focusing on the research and development and application of energy storage technology, GreenMore provides complete home energy storage solutions for users around the world. This article will analyze in detail from a professional perspective how to scientifically configure a suitable solar energy system based on your household electricity needs.

1. Determine the average daily household electricity consumption

To calculate the size of the solar system you need, you first need to know your home's actual daily electricity consumption. You can find this out by:

• Method 1: Check your electricity bill

Most power companies will show your monthly electricity usage (kWh) on your bill. Divide it by 30 to estimate your average daily electricity usage.

Example: If your monthly electricity usage is 300 kWh, your average daily electricity usage is about 10 kWh.

• Method 2: Manually calculate the power consumption of major electrical appliances

List the power (W) and daily operating time (h) of commonly used electrical appliances in your home, and estimate using the formula Power × Time = Power Consumption (Wh).

The capacity of the energy storage battery is configured according to the number of days set

The energy storage system needs to be configured with redundant capacity according to local climate conditions. Taking Beijing as an example, the average number of consecutive rainy days per year is 2.3 days. It is recommended that the energy storage capacity be calculated according to the following formula:

Energy storage capacity (kWh) = battery charge and discharge efficiency × discharge depth average daily power consumption (kWh) × self-sufficient days (days)

For example, if a household with an average daily electricity consumption of 30 kWh requires self-sufficiency for three days and uses a lithium-ion battery with a charge and discharge efficiency of 90% and a discharge depth of 80%, it needs to be equipped with: 0.9×0.830×3=125kWh

2.Calculate the required solar system capacity

Once the average daily electricity consumption is determined, the required solar system installed capacity (kW) can be further calculated.

• Calculation formula:

Required system capacity (kW) = average daily electricity consumption (kWh) ÷ daily exposure hours (h)

Note: Peak Sun Hours refers to the standard sunshine time when the sunlight intensity reaches 1000W/m², which varies slightly in different regions. For example, in southern China, the average sunshine hours are about 4 hours/day.

Example:

If the average daily electricity consumption is 10 kWh and the average sunshine time is 4 hours, then:

Required system capacity = 10 kWh ÷ 4 h = 2.5 kW

This means that to meet your electricity needs for a day, you will need to install at least a 2.5 kW solar system.

3. Consider the supporting needs of the energy storage system

Although solar energy systems can generate electricity during the day, household electricity consumption is often concentrated in the evening and at night. Therefore, in order to achieve true "self-generation and self-use", we recommend using an energy storage battery system.

Energy storage battery capacity selection recommendations:

1. If the system capacity is 3 kW, a 5–10 kWh energy storage battery is recommended;
2. If the system capacity is 5–6 kW, a 10–15 kWh energy storage battery is recommended;
3. If you want to achieve 24/7 off-grid operation, you can choose a higher capacity energy storage system, such as the stacked energy storage battery or home energy storage system provided by GreenMore.
