In general, the contribution of current harmonics from solar PV inverters does not pose a significant power quality issue. The current total harmonic distortion (ITHD) from a quality-brand inverter is typically low and negligible compared to harmonics-producing loads such as variable speed drives, where ITHD for a typical 6-pulse drive ranges between 30% – 50%.

Typically, a quality-brand inverter's datasheet will state a Current Total Harmonic Distortion of around 3%.

In Singapore, for a Grid-Tied Solar PV connection, the Licensed Electrical Worker (LEW) must submit the inverter’s power quality-related type test report to the grid operator (SP Group). One such example is the portion of the report where the inverter was tested as part of the UK Engineering Recommendation G99 requirements, showing that quality-brand inverters have harmonic current emission values well within acceptable limits.

One might wonder about the cumulative effect of multiple inverters. Measurements at several sites with cumulative rated PV outputs exceeding 1MWac provide some insight.

Here are two such sites where background harmonics were relatively low, making the inverter effects more representative (with limited 'contributions' from the local electrical network).

All measurements were performed using IEC 61000-4-30 Class A certified Power Quality instruments. The Current Harmonic Distortion (ITHD) trends were scaled to the respective aggregated inverters’ rated current, shown here as Total Demand Distortion (TDD) values. Observations indicate TDD values were less than 3%, with the sinusoidal shape of the current waveforms still visible.

Note: IEEE 519 recommends TDD values of 5% for power generation facilities.

Site #1:

• Premises Type: Warehousing / logistics
• PV Size: 1352.8 kWp
• Aggregated Inverter(s) Rated Current: 1613A @ 400V
• Measurement Point: 2500A PV-AC distribution board, directly connected to the premises' 5000A Main Switchboard (served by a 3MVA transformer) via 3000A flexible CTs (clamped on 3 sets of 500sqmm cables per phase)
• VTHD: 0.89% – 3.96% (CP95: 3.6%)

Site #2:

• Premises Type: Solar Farm (with on-site auxiliary power and lighting loads only)
• PV Size: 2652kWp (for CS1)
• Aggregated Inverter(s) Rated Current: 62A @ 22kV (for CS1)
• Measurement Point: 22kV Incomer 1 from PowerGrid (CS1) via VT and CT. The solar farm was connected to a lightly-loaded 22kV distribution network
• VTHD: 0.59% – 1.22% (CP95: 1.09%)

These measurements indicate that even with multiple inverters, the harmonic distortion remains low, and the current waveforms retain their sinusoidal shape. Therefore, while solar PV inverters do generate harmonics, their impact on power quality is generally minimal when high-quality inverters are used and the system is properly designed.

When integrating a photovoltaic (PV) system, the reactive power remains constant while the active power decreases, especially when PV generation matches consumption. This requires precise reactive power compensation to maintain a high power factor (PF).

To optimize power quality and meet grid standards, it is recommended to install an Active Harmonic Filter (AHF) that handles both harmonics and reactive power. The AHF effectively suppresses harmonics generated by the system and provides dynamic reactive power compensation, helping to stabilize the grid's power factor.

This solution enhances system stability and reliability, and also helps prevent equipment failures and energy losses caused by harmonics and reactive power issues.

YTPQC-AHF

Active Harmonic filters are highly effective in addressing and resolving the aforementioned harmonic issues. They are specifically designed to detect and counteract the negative impacts caused by harmonics, ensuring a more stable and clean power supply.

By actively filtering out the harmonic components, active power filters help to maintain the quality and integrity of the electrical system, minimizing the disturbances and potential damage that harmonics can bring. Their application is crucial in various industries and power systems to achieve optimal power performance and reliability.

The choice between integrated solar street lights or split solar street lights depends on the specific usage environment and requirements. Here are their respective characteristics and advantages and disadvantages for reference:

Integrated solar street lights

Advantage:

Compact design, easy installation and maintenance, no need to lay too many wires and cables.

Can save space without occupying ground space.

Integrated with solar panels, energy storage batteries, and control systems, it has independent power supply capability.

Using solar energy as the main power supply is environmentally friendly and energy-saving.

Disadvantages:

The charging efficiency and light compensation capability are affected by weather conditions, which may lead to insufficient charging and lighting time in areas with continuous rainy weather or insufficient winter sunshine.

High cost and initial investment.

Split solar street light

Advantage:

The solar panels and LED lights are installed separately, and the solar panels can be adjusted according to the optimal angle of lighting conditions to achieve higher charging efficiency.

The independent design of solar panels and lamp heads can improve system flexibility and practicality.

The wire connection between the solar panel and the lamp head is relatively short, reducing line loss and safety hazards.

Disadvantages:
Installation and maintenance are relatively complex, requiring the arrangement of more wires and cables.

Occupying a significant amount of ground space.

Split design may result in higher overall system costs.

The best choice depends on specific needs and usage environment. If the environmental lighting conditions are good, a street light system that requires simple installation and maintenance, and can tolerate high initial investment costs, integrated solar street lights may be a good choice.

If it is necessary to adjust the optimal installation angle according to the lighting conditions, have high flexibility requirements for the street lamp system, and can arrange more installation space and manpower resources, split solar street lamps may be more suitable.

Solar panels alone cannot provide power during a power cut unless they are part of a system that includes a battery storage solution or a special inverter capable of operating independently of the grid. Here’s a detailed look at the different configurations and how they perform during a power outage:

On-Grid Solar Systems

How They Work:

Connection: These systems are directly connected to the local utility grid.

Operation: During normal operation, the solar panels generate electricity, which is used to power your home. Excess electricity is sent back to the grid, often earning you credits or compensation.

Power Cut Scenario: In the event of a power cut, on-grid systems automatically shut down for safety reasons (to protect utility workers from potential electric shocks).

Solution:

On-Grid systems require additional components to work during power cuts:

Battery Storage: Adding a battery to your system allows you to store excess solar energy, which can be used during a power outage.

Hybrid Inverter: These inverters can switch to battery power and operate independently of the grid during outages.

Off-Grid Solar Systems

How They Work:

Connection: These systems are not connected to the utility grid and are designed to be self-sufficient.

Components: They rely on batteries to store energy generated by the solar panels, ensuring power availability when there is no sunlight.

Power Cut Scenario: Off-grid systems continue to provide power during a grid outage since they are not dependent on the grid.

Solution:

Off-grid systems are inherently capable of providing power during outages due to their reliance on stored energy in batteries.

Hybrid Solar Systems

How They Work:

Connection: These systems combine the benefits of both grid-tied and off-grid systems.

Operation: They can be connected to the grid and have battery storage for backup power.

Power Cut Scenario: During a power outage, a hybrid system can switch to battery power, ensuring a continuous supply of electricity.

Solution:

Hybrid systems are ideal for ensuring power during outages while still being able to benefit from grid connectivity and net metering.

Key Components for Backup Power

1. Batteries

Function: Store excess energy generated by solar panels.

Types: Lead-acid, lithium-ion, and other advanced battery technologies.

Consideration: Size and capacity of the battery should match your energy consumption needs.

2. Inverters

Function: Convert DC electricity generated by solar panels to AC electricity used by home appliances.

Types:

Standard Inverter: Works only when connected to the grid.

Hybrid Inverter: Can switch to battery power and operate independently during a power outage.

3. Charge Controllers

Function: Regulate the amount of charge going into the batteries to prevent overcharging.

Solar panels alone will not provide power during a power cut if you have a standard grid-tied system. To ensure your solar panels work during outages, you need either an off-grid system, a grid-tied system with battery storage, or a hybrid system. For a reliable backup solution, investing in a battery storage system and a hybrid inverter is essential. This setup not only provides power during outages but also maximizes the use of renewable energy generated by your solar panels.

1. What is the shape of your roof?

Roofs come in many different shapes and sizes. Before you go ahead with any installation, make sure that your roof has enough space for the rooftop solar panels. If there isn’t enough room, you likely will not get the return you expect on your investment.

2. Where will the water go?

When it rains, water runs down the roof, into the gutters and out and away from your home. When installing solar panels, equipment like solar panel roof brackets and wire harnesses can prevent the water from flowing and draining properly. In some cases, solar equipment can move the water in a different direction, which can create leaks and other problems. These problems will need repair, which means the solar panels will need to be removed.

3. Did you pick the cheapest options?

Cheaper solar panels rarely translate to better solar panels. While the technology has dropped significantly in price over the past decade, investing in the cheapest models or brands of solar panels can leave you in the dark. Cheaper or low end solar panels are often manufactured in a way that makes them less durable. When solar panels are less durable, it decreases your investment value as well as potential future savings. The scary part is that these lower quality panels can sometimes be dangerous, resulting in safety hazards. The last thing you want is to have a fire start in your home because of low quality solar panels.

4. What about warranties?

Warranties are an important aspect of protecting your solar panels and other related equipment. If anything happens to your solar panels, having a warranty helps you to keep the manufacturer accountable — without any additional cost to you. There are also some incentive programs (available in many different states) that require you to have a warranty for your solar equipment.

5. Don’t forget about maintenance.

Keeping your solar panels working and your roof in good condition is all about establishing proper maintenance procedures. It’s a good idea to find out from rooftop solar panel manufacturer what those maintenance procedures are before the installation begins. If you are unable to meet those maintenance requirements, there is a good chance your equipment will not last as long as you want it to.

The upper limit of the charging voltage of a single lithium iron phosphate battery is 3.65V. Generally, the upper limit voltage of lithium iron phosphate battery charging is 3.7~4V, and the lower limit voltage of discharging is 2~2.5V. The voltage of lithium battery is one of the important indicators to measure the discharge performance of lithium battery. The unit is volts.

LiFePO4 battery voltage
Common 18650 batteries are divided into lithium-ion batteries and lithium iron phosphate batteries. The voltage of lithium ion battery is 3.7v nominal voltage, the charging cut-off voltage is 4.2v, the nominal voltage of lithium iron phosphate battery is 3.2V, the charging cut-off voltage is 3.6v, the capacity is usually 1200mAh-3000mAh, the common capacity is 2200mAh-2600mAh .

Why is the lithium iron phosphate battery voltage 3.2V?
Lithium iron phosphate battery refers to a lithium ion battery using lithium iron phosphate as a positive electrode material. The cathode materials of lithium-ion batteries mainly include lithium cobalt oxide, lithium manganate, lithium nickel oxide, ternary materials, lithium iron phosphate, etc. Among them, lithium cobalt oxide is the cathode material used in the vast majority of lithium-ion batteries.

The nominal voltage of the lithium iron phosphate battery is 3.2V, the high end charge voltage is 3.6V, and the low end discharge voltage is 2.0V. Due to the different quality and process of positive and negative electrode materials and electrolyte materials used by various manufacturers, there will be some differences in their performance.

3.2V lithium iron phosphate battery, which can be discharged in large capacity. Now all electric vehicles use this kind of battery. This kind of battery has a long life and light weight! 3.6V and 3.7V are the same as polymer lithium batteries. The upper limit of polymer lithium batteries is 4.2 and the lower limit is 2.6. The general standard is 3.7V.

The charging voltage of the lithium iron phosphate battery should be set at 3.65V and the nominal voltage is 3.2V. Generally, the maximum charging voltage can be higher than 20% of the nominal voltage, but if the voltage is too high, the battery may be damaged. The 3.6V voltage is lower than this indicator. Not overcharged. If the battery is set to a minimum of 3.0V, it needs to be charged, then 3.4V is 0.4V higher than the minimum, and 3.6 is 0.6V higher than the minimum. This 0.2V can release half of the power, which means that each charge is half more than 3.4V. Use time, because the battery is used for a certain number of times, the life is increased by half, so increasing the charging voltage will increase the battery life without damaging the battery.

The discharge platform of the lithium iron phosphate battery is: 3.2V
The discharge range is: 2.5-3.65V
This maximum charging value can be changed according to customer needs (protection board parameters)
Generally, the maximum charging voltage is set at 3.85V
When it reaches 3.85V, the protection voltage is reached, and the protection board will automatically cut off the charging circuit to protect the battery.

Li-ion battery voltage

The discharge platform of the lithium-ion battery refers to the voltage change state of the battery when the fully charged lithium battery is discharged. When the battery is discharged with constant current, the battery voltage has to go through three processes, namely, decrease, stabilize, and decrease again. Among these three processes, the stabilization period is the longest. The longer the stabilization time, the higher the discharge plateau of the battery. The level of the discharge platform is closely related to the battery manufacturing process. It is because the market positioning of each lithium battery manufacturer is different, the technical process is different, the discharge platform controlled by it is different, and the quality is also very different.

Generally speaking, a 18650 lithium battery has a full voltage of 4.2V, and when it is discharged to 3.7V with a 1C current for 60 minutes, then we say that the battery has a capacity of 2200mAh. Nominal voltage, also known as rated voltage, refers to the voltage exhibited by the battery during normal operation. The nominal voltage of lithium batteries is generally 3.7V or 3.6V.

Depending on the cathode material of the lithium battery, the nominal voltage will vary. The nominal voltage of lithium cobalt oxide battery is 3.7V; the nominal voltage of lithium manganate battery is 3.8V; the nominal voltage of lithium nickel cobalt manganese ternary material is only 3.5-3.6V, but with the continuous improvement of formula and structure Perfect, the nominal voltage of the lithium battery of this material can reach 3.7V; the nominal voltage of the lithium iron phosphate battery is the lowest, only 3.2V, but the lithium battery of this material is very safe, will not explode, and the cycle performance is very good and can reach 2000 week.

Lithium-ion batteries have high working voltage (three times that of nickel-cadmium batteries and nickel-hydrogen batteries), large specific energy (up to 165Wh/kg, three times that of nickel-hydrogen batteries), small size, light weight, long cycle life, and self- Low discharge rate, no memory effect, no pollution and many other advantages. Among lithium-ion batteries, lithium iron phosphate batteries are more promising. Although this battery has lower specific energy than lithium cobalt oxide batteries, it has high safety and large single battery capacity.

The above is the voltage of lithium iron phosphate battery and the voltage of lithium ion battery. When choosing a lithium battery charger, you should pay attention to the output voltage of the charger. The charging mode is constant current + constant voltage.

As a popular new energy battery, lithium iron phosphate batteries have become popular in recent years because of their own problems, such as whether lithium iron phosphate batteries can continue to be used, or how to repair or what is the cause of swelling . Next, we will make a comprehensive understanding of the protruding problem of lithium iron phosphate batteries.

LiFePO4 battery swelling

1. Reasons for the expansion of lithium iron phosphate batteries

(1) Manufacturing level

The bulging of lithium ion batteries may be the manufacturing level of lithium iron phosphate battery packs, the electrode coating is uneven, and the production process is relatively rough.

(2) Bumps caused by overcharging of lithium-ion batteries

Overcharging will cause all the lithium atoms in the positive electrode material to run into the negative electrode material, resulting in the deformation and collapse of the full grid of the original positive electrode, which is also an important reason for the decrease in the battery capacity of the lithium iron phosphate battery. During this process, more and more lithium ions are deposited on the negative electrode, causing the lithium atoms to grow into stumps and crystallize, causing the battery pack to swell.

(3) If the lithium iron phosphate battery is not used for a long time, swelling will also occur, because the air has a certain conductivity. Therefore, if the battery is left for too long, it is equivalent to direct contact between the positive and negative electrodes of the battery, resulting in a chronic short circuit.

(4) Excessive expansion

During the first charge-discharge process of a liquid lithium-ion battery, the electrode material reacts with the electrolyte at the solid-liquid interface to form a passivation layer covering the surface of the electrode material. The formed passivation layer can effectively prevent the passage of electrolyte molecules, while Li+ can be freely embedded and exuded from the passivation layer, which has the characteristics of solid electrolyte. Therefore, this passivation layer is called SEI. SEI films are not set in stone. During the charging and discharging process, there will be some changes, the important ones are the reversible changes of organic matter. After the lithium iron phosphate battery pack is overdischarged, the SEI film will be reversibly damaged. When the SEI protecting the anode material is destroyed, the anode material collapses, resulting in a bulge phenomenon.

(5) The violent reaction of the short circuit will generate a lot of heat, which will decompose and evaporate the electrolyte and cause the battery to expand.

(6) Reasons for the low quality of lithium iron phosphate battery chargers. Chargers are made of low-quality circuit boards, innovative or low-quality components. Due to inaccurate heating and parameter drift, the charging voltage limit is out of control, resulting in kneading and deformation of the gas inside the lithium-ion battery, resulting in cracking or even bursting of the battery casing.

(7) Long-term use of lithium iron phosphate batteries will also cause swelling, because the air has a certain conductivity, so if the battery is placed too long, it is equivalent to direct contact between the positive and negative electrodes of the battery, resulting in a slow short circuit.

2. Repair the swelling of lithium iron phosphate battery

(1) When the battery expands, first seal the battery with plastic wrap and put it in the refrigerator to cool for about half an hour.
(2) Remove the battery after cooling down, and then remove the wrapping paper on the surface of the battery.
(3) Then use a needle to pierce a small hole on the surface of the lithium-ion battery package.
(4) Press with your fingers to discharge the gas in the battery.
(5) Seal the air holes with tape.

3. The expansion of lithium iron phosphate batteries will reduce the capacity

During the expansion process, the capacity of the lithium-ion battery pack is reduced, and the battery life is significantly shortened. In severe cases, battery life can be short or unusable. At this time, the battery is usually replaced, for safety or to buy a new battery.

4. Can the lithium iron phosphate battery still be used after it is fully charged?

It is not recommended to use the lithium iron phosphate battery after it is fully charged. During the charging process, the capacity of the lithium-ion battery pack decreases, and the battery life is significantly shortened. In severe cases, battery life can be short or unusable. At this time, the battery is usually replaced, for safety or to buy a new battery.

When the lithium-ion battery pack has bulging problems, it is best not to continue using the battery in question. Due to the expansion of the battery, when the expansion reaches a certain limit, it may cause an explosion, which is very dangerous. For your own safety, it is best to replace the lithium-ion battery pack as soon as you notice swelling.
