Solar inverters are essential devices that convert the direct current (DC) produced by solar panels into alternating current (AC) suitable for home and industrial use. The 100Mw solar inverters are particularly ideal for large solar farms because they are scalable. A large farm can have several hundred MW of output inverters. There are several solar inverters, including:
String inverters
String inverters are the most common type of inverter used in solar photovoltaic (PV) installations. They are mainly used in systems that have a small number of solar panels. This type of inverter connects a series of solar panels (or a string) into one unified DC output that is then converted into AC power by the inverter. The main advantage of string inverters is their affordability. However, they have a major issue of performance mismatch. If one panel in the string is shaded or soaks up heat, it affects the whole string's performance. This makes them unsuitable for large installations.
Centrally-mounted solar inverters
Centrally mounted inverters are the mainstays in large solar power plants. They integrate the strings of several solar panels into a DC output first before carrying out the conversion into AC power. This arrangement enables the inverter to DC output at high levels which is then converted into AC power within the central inverter. The large scale and high production capacity of these inverters makes them suitable for large plants. However, they tend to be expensive and require a large roof or ground area.
Micro-solar inverters
Micro-solar inverters are installed on each solar panel. They convert the DC power of each panel individually into AC power. This means even if one panel has a problem, the inverter connected to the panel will still work. This makes it ideal for homes that use different types of PV panels and might experience problems of shading or soaks up heat. The major problem with micro-solar inverters is their high installation costs compared to string inverters.
Off-grid inverters
Off-grid inverters, also known as standby or backup inverters, are used to power systems not connected to electricity supply grids. These inverters are used in homes or remote communities that rely on solar power alone. They store energy in batteries, providing a reliable power source when needed. There are battery-based and batteryless inverters. Battery-based inverters store energy in batteries. When there is no grid power, the batteries supply the required power. Batteryless inverters don't use batteries. Instead, they connect to the electrical grid to provide constant power.
Hybrid solar inverters
Hybrid inverters are similar to off-grid inverters. These inverters can draw current from the grid, battery, and solar panels. They are often used in systems that need reliability and sustainability. Hybrid inverters will work if one or more current sources are unavailable. For example, if the electrical grid loses current, hybrid inverters will still provide power. They will do this by drawing current from the solar panels and battery.
Solar inverters have various industrial applications, including:
Commercial buildings
Solar inverters in commercial buildings enable businesses to reduce their dependence on the electrical power grid. This is achieved by harnessing and utilizing energy from the sun. The reduction in dependence results in a significant reduction in energy costs. Inverters also ensure that the energy utilized is of high quality and reliable. This enables the buildings to efficiently power all their lighting, heating, and computing systems. For sustainability-conscious organizations, solar inverters will help reduce the carbon emissions associated with the use of fossil fuels to generate electricity.
Industrial manufacturing facilities
Many industrial manufacturing companies utilize large amounts of electricity in their operations. Solar inverters in these facilities help offset their electrical energy needs by converting the DC into AC current. This current can be used to power the complex machinery and equipment found in these manufacturing processes. Besides, using inverters to harness solar energy helps these companies to lower their operational costs by reducing electricity bills. This is especially cost effective if the facility is located in an area that receives abundant sunlight. Another benefit is that lower electricity costs increase safety in the operations because less money needs to be spent on power. In addition to the cost savings and power availability, many governments provide incentives to manufacturing plants that use renewable energy.
Telecommunication systems
Telecom companies rely on consistent and steady power to operate their network systems. 100mw solar inverters ensure these companies can obtain power by converting solar energy into usable electricity. This continuous operation protects the systems against power shortages. Also, many telecom companies are utilizing green energy to power their systems. This helps in reducing environmental impact and improving their reputation as environmentally friendly organizations.
Transportation hubs
Transportation hubs such as airports and bus stations use large amounts of electrical energy for lighting, heating, air conditioning, and electronic ticketing systems. Solar inverters installed in these hubs help to offset their electrical energy needs. This is achieved by converting solar energy into useable electricity. Many of these transportation hubs are located in open areas with few tall buildings that might cause shading to the solar panels. This makes them ideal locations for harnessing large amounts of solar energy. Also, many government agencies are setting targets for the decarbonization of transport net. They are also providing financial incentives for the utilization of renewable energy.
Maximum direct current (DC) input voltage
The maximum DC input voltage is the highest voltage that can be safely handled by the inverter. Going over this voltage can damage the inverter. The maximum DC input voltage varies from inverter to inverter, so always check the manufacturer's instructions. They will give this information. The maximum DC input voltage is normally determined by the type of solar panel used in the system.
Maximum AC output voltage
The maximum AC output voltage is the highest voltage that can be delivered by the inverter. Higher voltages enable the inverter to service a large area. Just like the DC input voltage, the maximum AC output voltage also varies between inverters. Generally, it's determined by local grid standards. This means it's important for users to know the electrical grid standards in their respective local areas. This helps them select the right inverter that meets these standards.
Maximum direct current (DC) output circuit
This is the highest current level that can be handled by the inverter's output circuit. Higher currents improve the electrical system's efficiency. Just like the previous two specifications, this one also varies depending on the inverter used. Always check the manufacturer's guidelines for this information before starting the operation.
Operating temperature range
This specification indicates the temperature range where the inverter can operate effectively. This means the inverter should not be subjected to temperatures outside this range. Excessive heat or cold can damage the internal components of the inverter. Different inverters have different operating temperature ranges.
Maximum efficiency
In simple terms, the maximum efficiency refers to how effective the inverter can be in converting DC power to AC power. Higher power efficiency is always an advantage. However, don't let it mislead you. Maximum efficiency is never the same as nominal efficiency. Maximum efficiency is only measured under laboratory situations. Whereas nominal efficiency is measured under normal usage.
(This is a general guideline on how to install a 100Mw solar inverter. Actual procedures may vary, depending on the manufacturer, local regulations and the electrical grid conditions. Always consult a professional). Here are the steps to consider:
Mounting of solar inverter
In a solar power system, the inverter is normally mounted close to the solar panel connection point. This is done to minimize the energy loss during the power transfer from the panel to the inverter. Use an electrical conduit to safely mount the inverter onto a wall. Ensure the mounting location is shaded from direct sunlight. This is because excessive heat can cause inverters to overheat.
Electrical connection
Begin by connecting the solar panels to the inverter. After connecting the panels to the inverter, connect the inverter to the electrical grid. Inverting the electrical connection to the grid will enable the inverter to stop operating if there are any electrical issues. After making connections, always use a multimeter to check the voltage and current. This ensures there are no electrical issues.
Configuration setup
Once the inverter is connected to the solar panels, grid, and electrical load, configure the inverter settings. These settings include output voltage and power. They also include current and frequency. The configuration process is different for different inverters. Always remember to refer to the manufacturer's guidelines for the correct configuration procedures.
Initial testing
After completing the installation and configuration process, test the inverter. The testing process involves checking the output voltage and current. This is done by using a multimeter. This means the multimeter is connected to the inverter output terminal. Once the inverter is turned on, it will output voltage. This voltage can be measured. Also, for safety, use a clamp meter to check the output current. This ensures the output current is within safe limits.
Final commissioning
After successfully testing the inverter, finalize the commissioning process. This is done by formally connecting the inverter to the electrical grid. To do this, the anti-islanding protection feature is disabled. This means the inverter will be allowed to operate in island mode. In this mode, the inverter will keep generating current even if there is no grid power. With this Frankfurt generation of current, there will be a connection between the inverter and grid power.
Use quality materials
To get an ideal inverter, manufacturers should use quality materials. They should ensure the components materials used are of good quality, durable enough to withstand the company's operating conditions, and heat conductive.
Utilization of latest technology
Manufacturers should use advanced technological components like maximum power point tracking (MPPT) to improve efficiency. The newest tech gadgets are more efficient and can easily handle large power volumes.
Regular testing
Testing shouldn't happen only once after producing the inverter. The testing should always be done regularly on every batch produced. This helps identify problems before they become one. Also, testing gives room for improvements.
Customer feedback
Don't just wait for the customer complaints after using the product. Gather the feedback and utilize it. This feedback can help identify and improve quality issues.
Regular inspection
Regular inspection and maintenance are the secrets to prolonging the lifespan of 100Mw solar inverters and deriving optimal performance from them. For maintenance, buyers have to set schedules for regularly inspecting their solar inverters. During the inspection, look for physical issues like burned or cracked components. Also, check for signs of electrical problems like scorching or melted wires. Listen for strange noises or humming. All these will have been indications there are issues needing solutions.
Cleaning
Inverters have fans and vents used for cooling purposes. Because of their constant operational nature, they tend to generate dust over time. Dust will block the vents and reduce air circulation. Poor air circulation means the inverter will overheat. In some cases, the overheating will make the inverter shut down to protect itself from damage. In other cases, it will decrease its productivity. To avoid this, regularly clean the fans and vents using a soft brush and cloth. When doing this, don't use water or harsh chemicals. They will damage the inverter. Always conduct cleaning when the inverter is off. This guarantees cleanliness without posing any danger.
Software updates
Inners have software that will need to be updated constantly. These software updates improve the inverter's performance and security and solve any previously known problems. The good news is most modern inverters have automatic updates. They will check and install the newest software versions. However, there are some that require manual checks for updates. For such inverters, always check the manufacturer's website for the latest software versions and installation procedures. Updates will usually be provided after a specified duration. So, it's the responsibility of buyers to make sure their inverters are running on the newest software version.
Professional servicing
When it comes to maintenance and servicing of 100Mw solar inverters, many people have this one thought in common: will I do it myself or hire a professional? The inverter's inner workings, including its circuit and electrical components, can be quite complicated. This makes self-maintenance difficult. There are many methods for which DIY can be effective, such as routine cleaning and inspection. However, other things like electrical components are better left to the experts. They have the necessary experience and skills required. Besides, professional services have the guarantee to quality. Just ensure electing a well-known professional.
