What are string inverters?
A photovoltaic (PV) solar system is not complete without the solar inverter, an essential component that operates in the background. It takes the energy generated by the modules and transforms it from direct current (DC) into alternating current (AC), making the energy usable. The inverter is responsible for monitoring and managing the performance of the solar modules as well as the characteristics of the grid. This not only guarantees that the PV system is operating safely but also that it is producing high yields.
The most recent advancement in inverter technology, known as contemporary string inverter technology, is the one that offers the highest level of safety, reliability, and performance.
There are five primary reasons why string inverters are the most suitable option for you to go with:
1.Advantage of string inverters with your system: It is much safer
When compared to systems with DC optimizers and micro-inverters, systems created with string inverters have a reduced number of electrical components, which helps to reduce the risk of connection hazards. The introduction of new connection points inside a PV system brings with it the possibility of new fire hazards. Because there are a substantially lesser number of connection points inside a string inverter system, string inverters are the system of choice when it comes to safety.
In addition, string inverters generate very low levels of electrical noise, which increases the accuracy of arc fault detection and the shutdown dependability of the system. Both of these tasks are essential to the safety of the system. Systems with high noise levels or systems that do not detect arc faults do not satisfy this critical safety aspect.
When a photovoltaic (PV) system is constructed with fewer components than string inverters, technicians will spend less time on your roof, which significantly minimizes the danger of physical injury or property damage from an accident that occurs on your roof.
2. Advantage of string inverters with your system: They are more reliable
Mounting electronics in the severe climate of a roof increases the likelihood that individual components will fail. Solar photovoltaic (PV) systems that are built with string inverters do not require any additional components to be added to individual solar modules. Because every component has a certain rate of failure, increasing the number of components in a system will invariably result in a decline in the reliability of the system. It will become increasingly necessary for service experts to go to the roof of your home in order to replace components that have failed.
In order to improve overall reliability, string inverters are often put in a location that is less severe than the surrounding environment, such as in the garage or on an exterior wall. As a result, the inverter may be reached without much difficulty in the event that it requires servicing or maintenance. The fact that technicians do not have to climb on your roof eliminates one potential source of injury for both the technician and you.
Active cooling in string inverters maintains cool temperatures for the electronics, which results in improved performance and a longer life. This ensures that the system will function reliably for a longer period of time.
You will be provided with granular insight into your system via the monitoring platform of the inverter, which is also accessible via mobile apps. Additionally, you will be notified if your system requires care. String inverters are able to accomplish all of this without the need to install expensive and unstable circuitry to each and every module.
3. String inverters are more cost-effective
Solar systems are significantly more expensive than string inverter systems. This is because DC optimizers and micro inverters require expensive power electronics to be installed on each and every solar module. Additionally, the installation of solar systems requires significantly more labor due to the increased number of components. However, this is not the end of the story. Because of the high number of components, there will be more system failures throughout the course of the system’s lifetime, which will result in higher costs for operation and maintenance.
4. String inverter is a better investment
The string inverter technology is future-proof and versatile due to the fact that it is built on open industry standards. This allows for future system updates or expansions to be easily achievable. The fact that string inverters are located in an easily accessible position rather than hidden behind PV modules on the roof makes it simple to do maintenance on them. DC optimizers and microinverters, on the other hand, are often incompatible with other technologies and provide you with a restricted range of brand options.
The decision couldn’t be simpler. String inverters are the ideal technology for your solar power system because they outperform classic DC optimizers and microinverters, which are also known as traditional module-level power electronics. Modern string inverters win out these older technologies in every area.
5. String inverters produce more energy
No matter if the system is situated on a complex roof or if it is shaded, the latest string inverters contain cost-effective software improvements that maximize the amount of power generated by the system. This removes the requirement for installing expensive gear on the roof and provides you with the maximum energy production that is achievable.
The combination of lower costs upfront as well as for service and maintenance and better overall performance will lead to a superior return on your investment over the next 20 years as well as peace of mind during that time period.
