Solar Inverter Buying Guide
Most people are making the switch to solar appliances to save energy and eliminate the hassle of power outages. However, picking a suitable inverter for your home or office could still be a tough decision.
Here’s a complete Solar Inverter buying guide for you to consider before making the right choice.
What is a Solar Inverter?
A solar inverter is an electric device that uses photovoltaic solar panels to convert the direct current generated into alternating current with the frequency used to run home appliances. Usually, an inverter consists of four components:
- Solar Panel
- Charge Controller
How Does a Solar Inverter Work?
In a photovoltaic cell, a layer of positive or negative layers is combined with a junction. These layers absorb sunlight and then pass it to the photovoltaic cell made of semiconductor layers of crystalline silicon. As the energy runs around, electrons jump between positive and negative layers producing a direct current.
This direct current is then passed on to the inverter with large capacitors that convert it into alternating current.
How Long Do Solar Inverters Last?
How long a solar inverter lasts can depend on the kind of inverter you have, but in general, solar inverters typically have a lifespan of around 5-12 years.
Different Types of Solar Inverter Available
You will find various types of solar inverters readily available in the market. Here are two categories based on which the devices have been classified.
- String Inverters
- Central Inverters
Interaction With Grid Power
- Stand-alone inverters
- Grid-Tie inverters
- Backup Battery inverters
In such inverters, a string or a row of solar panels are connected. For example – if there are 16 panels on your roof with 4 panels in each row, you have 4 solar strings. All these panels are connected in a series connection that is further connected to the inverter.
String inverters are primarily found in residential buildings with one string only. These inverters are convenient to install and cost less than other types. Usually, the strings of solar panels are in an easy-to-access location that simplifies the maintenance and repair work procedure.
However, if a single panel stops working, the overall performance of the inverter is heavily affected. Therefore, such inverters should be installed if the roof gets consistent sun.
Central inverters are a form of larger string inverters where multiple strings are in use. Instead of connecting the output directly to the inverter, a container box is used in the case of central inverters.
Such inverters are helpful in the case of large setups, like that of 5 MW. Like string inverters, central inverters are also affected by shading and can lose up to 50% energy with even 10% coverage. However, these inverters are cheaper as compared to string inverters.
In the case of micro-inverters, there is a small inverter connected behind each solar panel. It converts the direct current received into alternating current. The AC supply is then merged and passed on to the power grid.
These inverters promise 25% more output than string or central inverters. Here, each panel’s energy is initially stored separately. It means that in the case of shading, the exposed panels are still performing their best.
However, these inverters are costlier than other options, and it is tough to maintain them.
Stand Alone Inverters
These inverters use rechargeable batteries to draw DC power and convert it into AC power. The battery is connected to solar panels and utilises DC power generated by those panels to remain charged.
As the name suggests, stand-alone inverters are helpful if someone wants to go completely off-grid or in rural areas with no electricity connectivity.
These inverters are connected to a local grid and send the generated power back to the grid. Here, the DC power generated is sent to the grid-tie inverter. This inverter further converts it into AC power and sends it to the local grid.
Such inverters have anti-island protection and shut down during power outages to protect the repairman working on the grid.
Backup Battery Inverters
Here, the solar panels produce DC power sent to the battery to get stored. Then, the battery power is transferred to the inverter for DC to AC power conversion. In case the battery is fully charged, the produced power is sent to the local grid.
These inverters are costly but adequate if you are likely to suffer from regular power outages.
Factors to Consider Before Buying Solar Inverters
If you are heading out to take the right step and purchase a solar inverter, here are a few points you should definitely consider.
Safety Certification Certificate
Like any other electronic device, it is equally important to check the safety certification of any solar inverter. A good choice will be to see if it has any independent testing laboratory marking.
Check for Durability
Solar inverters are long-time investments. To ensure that you are making the right choice, check the product’s durability and performance record under extreme weather conditions. Based on different geographical terrains, you will find that different inverters give different efficiency.
Choose the Battery Wisely
The life of any solar inverter is primarily dependent on its battery. Therefore, it is crucial that you check the battery capacity properly before making the purchase. Battery capacity is the number of hours your inverter can power the devices.
You can select the ideal solar inverter based on your daily power requirement and budget. A string inverter is a good idea if you are looking for an inverter in a residential setup. These inverters are considerably cheaper and work well in uncomplicated roof regions.
Based on where you want to install the solar inverter, it is essential to check if the panels are weather-proof or not. In case not, you might want to invest in a weather-proof cage for protection. It will ensure that your solar panels last longer.
Certain home appliances require higher power to start than they do to operate. In such cases, it is essential to note peak power, i.e., the highest power a solar inverter will supply for a short duration.
The Bottom Line
Solar energy is paving the way for a sustainable future. Not only is it environment friendly, but also cheaper, safer, and easier to maintain in the long run.
Many people are already making the switch and using solar inverters for their residential or commercial electricity supply. A solar inverter takes DC power generated by solar modules as an input. It then converts DC into AC at a specific frequency that helps run the home appliances.
There are various types of solar inverters available in the market, and selecting the right one can be a bit confusing. In that case, go through the buying guide and focus on the features best suitable for you.
