Solar panels collect energy from the sun by capturing rays and causing electrons to move within their cells. This creates direct current electricity (DC).
Inverters convert DC power to alternating current (AC). They do this by switching the wire connections on a converter.
Cost
Inverters are an essential component of solar power systems. They transform the DC electricity that is produced by your panels into AC energy for use at home or on the grid.
There are many different types of inverters available on the market, including string inverters, microinverters and battery inverters. Although they vary in cost and efficiency, all are designed to convert solar power into usable electricity.
Choosing an inverter is an important decision as it will determine the performance of your solar system. The best inverter will give you the best results and ensure that your solar system can meet your needs.
Inverters come in a variety of sizes, from small grid-tie models to connect and control one solar panel to large utility-scale inverters for megawatts (MW) installations. The size of your solar array will dictate the type of inverter that you need.
It is also worth looking at the warranty of your inverter. Some manufacturers offer a 5-plus-five year warranty. This covers parts and labour for years 1-4, and then only the parts are covered in year 5. This is a great way for your inverter to last a long time and not break down.
Although a high-quality inverter is a more expensive part of your system, it is vital to have one installed to ensure your system runs smoothly. The inverter should be included in the quote that you receive from your solar contractor and should cost between 8 to 9 percent of the total installation cost.
For single-phase budget models, the cheapest solar inverters are around $1,000. You will need a better quality inverter if you plan to install a larger system.
There are many brands on the market, so it is worth looking into which ones offer the best value and performance. Enphase, Fronius, and SMA are some of the most popular solar inverter brands.
These inverters have a great reputation for reliability and are usually the recommended choice by most of our CHOICE members. They offer many features and excellent customer support.
Efficiency
Your energy production and the amount of money you save on your bills will be affected by how efficient your inverter or solar panel is. The more efficient your system is, the better it will be.
You want the highest efficiency possible from your panels. This means you get the most power at the lowest cost. Ultimately, this comes down to how well your home’s solar system is designed, what kind of panel technology you’re using and whether you can maximize the sun’s potential for solar power production.
Ask your electrician or solar contractor how they calculate the efficiency of your solar system based on your roof layout. This information will be used to calculate the output power of your solar system.
A good way to determine how efficient your solar system is is to compare its power output with the power produced by your solar panels. This can be done by connecting a standard household outlet to the inverter’s socket and measuring how much current flows through it.
Inverter efficiency measures how efficient your inverter converts DC into AC power. However, most inverters achieve an average efficiency of 85 to 95 percent. Some inverters are better than others.
When you’re choosing an inverter, look for one that has a high efficiency rating and a long warranty. These things will make a big difference in how many years you can expect the inverter to function.
An inverter that is reliable and consistent will be easy to maintain. Some inverters even have smart monitoring capabilities that can help you see how much power your solar system is producing and how much it’s saving you on your energy bills.
A solar inverter with an anti-islanding function can be purchased to prevent your system’s shutting down if the grid goes down. This prevents any problems from occurring during blackouts and can also be a safety measure.
Maintenance
Any equipment that needs regular care requires maintenance. This includes cleaning, washing, and changing parts. The main goal of these activities is to reduce the risk of equipment failure and extend the life of assets.
There are various types of maintenance, including preventive, predictive, condition-based, planned, and scheduled maintenance. It is important that you determine which maintenance type is best for your business and your equipment.
Preventive maintenance is intended to identify potential problems before they become major problems. It also helps you keep costs down by avoiding emergency repairs that are needed when equipment fails.
Routine annual inspections and cleaning can help to ensure that your inverter is in good condition. This will prevent costly repairs. It will keep your solar system working efficiently by preventing dirt, dust and cobwebs causing corrosion or any other issues.
You should check for damage and make sure your inverter is functioning properly. If it isn’t, you should contact your solar installation company right away to have it checked out and repaired.
Depending on the size and location of your inverter, the amount of maintenance required will vary. The most common maintenance tasks include cleaning, inspection, and replacement of parts. This is typically carried out by a qualified service technician.
Although a solar panel doesn’t need to be cleaned as frequently as an inverter it should still be tested and inspected every few years to ensure it is still working as intended. You can also protect your solar panels from damage by installing a security fencing around them.
One of the most common issues with solar equipment is that it can become damaged due to dirt and humidity. This can affect the power generation process, making it difficult to produce electricity. It is also possible for the wiring to short circuit, which can cause a fire and far-reaching property damage.
Performance
Performance is crucial to ensure that your system produces maximum power output, regardless of whether you are looking at solar or inverters. An inverter that is reliable and accurate will give you an online monitoring system that will allow you to monitor your system’s performance throughout each day.
The main function of a solar inverter is to transform the Direct Current (DC) generated by your solar panels into Alternating Current (AC), which is the type of electricity your home can use. It will also monitor your solar array’s output and adjust voltage and current accordingly to maximise production and minimize losses.
Inverters are also important in keeping your home powered up during a power outage. It can draw a small amount of standby power from your battery, and will typically switch on at the first sign of a power outage.
It will also shut off when it gets too hot, so keep a close eye on its temperature rating. The surge capacity of the inverter is important to protect it from large current spikes.
Check the datasheet to learn more about your inverter’s performance. This will provide you with key numbers such as its peak efficiency and total distortion.
High peak efficiency is an indication of how efficient it can convert DC input to AC output. It is important to remember that this figure only represents your inverter’s peak efficiency window. This may not be the case all day.
Your inverter should also have a low total harmonic distortion (THD) value, which should be less than 6 percent of your total output. This is particularly important for sensitive electronics such as a recording studio, or television set.
Lastly, you should check the peak and RMS regulation on your inverter, as these values will help to maintain steady power output at times of peak demand. These values should be at a minimum of minus 5 percent, and peak voltage regulation at a minimum minus 10 percent.
