In line with the target of net zero emissions that emerged at the COP21 Paris in 2015 and consumer awareness about sustainable energy for the better future, solar inverter application is one of the most popular options in the world.
Regarding solar power utilisation, several inverter types may be an option, but what is a string inverter? Why can it be the perfect match to optimize the solar systems? This article will give you the information that you need.
What is a string inverter? And How Does it Work?
A string inverter, which has become so popular these days, is a device that plays the core role in a solar system that takes electricity from a DC (direct current) source and converts it into AC (alternating current) so it can be used to power all the electronics in the user’s daily life.
It’s called a “string” because it just needs one device to connect a group of solar panels together in a row. So if you have 10 solar panels, you only need one inverter box with a particular inverter cable to power the entire home. The string inverter is commonly compared with the microinverter. See microinverter vs string inverter for further information.
The working principle of a string inverter starts when the sunlight hits the solar panel, which is the source of DC electricity. The DC is transmitted to the inverter for a conversion process. An inverter equipped with Maximum Power Point Tracking (MPPT) constantly monitors and adjusts the system’s performance to ensure it operates at its highest potential. You can find this modern technology in Joeyoung Inverter manufacturer products.
The converted inverter current can power the device that you need to boost the quality of life sustainably and greenly. If you use hybrid mode, the excess energy can be stored in batteries to power during outages.
What Is A String Inverter: Key Features
The features of a string inverter can determine the quality and how advanced the technology it uses is, so that the inverter can operate effectively and efficiently. Then, what is a string inverter’s key feature?
DC to AC Conversion
Since its primary function is to convert the DC electricity generated from the solar panels to AC electricity, the first key feature is its conversion ability. You can choose Joeyoung inverter products with a proven track record of 98% efficiency to reduce energy losses during the conversion process.
Maximum Power Point Tracker (MPPT)
When choosing devices that can maximize the energy harvested from solar panels by constantly adjusting the system’s output, select a string inverter with a dual or multiple MPPT channels if the solar panels face different directions or have shading issues.
Cost-effectiveness
String inverters are known for their affordability compared to other inverters. They are entirely suitable for a residential system to optimize energy and decrease electricity costs in the long run.
Centralized Monitoring
String inverters have a simple and centralized monitoring system of the entire solar system’s performance from one point. Select a string inverter with the user-friendly monitoring options, just like the Joeyoung inverter, which supports real-time data tracking. Hence, it’s easy to know the performance, detect inverter failure, and track the energy production.
Simplicity in Installation and Maintenance
The string type inverter installation process is easier to install and maintain because it requires only one inverter to manage multiple panels. Look for an inverter with a clear manual, and ensure it includes good customer support.
Reliability, Longevity, and Scalability
Designed to last between 15 and 20 years, depending on the model, string inverters have become the choice of many customers. They are flexible and can be scaled up to accommodate larger systems or additional panels.
Compact Design
The string inverter has a compact and space-efficient body. This is why they are easy to install and integrate into residential or commercial setups.
Built-in Protection Features
Joeyoung inverter products have advanced safety features such as overload protection, short-circuit protection, reverse, and overheating protection. Joeyoung inverters have a built-in high-efficiency cooling system that reduces noise.
How String Inverters Optimize Solar Systems
Once you install the string inverter in your solar system, it can reduce your electricity bills by allowing you to use free energy from the sunlight. In several models, such as a hybrid or on-grid inverters, you can save the energy excess in a battery bank or send it back to the utility power to earn credits through net metering.
String inverter installation lets you maximize your solar investment, providing significant savings while contributing to a clean and sustainable climate.
Advantages Of a String Inverter
- Generally more affordable compared to other inverter types.
- Because of its simple design, the installation process is quicker and less complex compared to others.
- The joeyoung power inverter operates highly efficiently at 98%, so the energy loss during the operation is less.
- Easier to maintain and scalable
- Long lifespan and reliability
- Widely available in the world.
- Reduce the reliance on fossil fuels and coal, contributing to a greener future.
How To Choose The Best String Inverter?
First, know yourself about the system that will be installed in your space by asking yourself, “What size of power inverter do I need?” The inverter sizing can affect the efficiency of the energy you will use.
Choose Joeyoung inverter products as your partner because of their reliability with OEM and ODM services tailored to your needs.
Frequently asked questions
If a string inverter is in trouble or malfunctioning, the entire system may experience a drop in performance since all the solar panels are connected to the same inverter. Fortunately, most string inverters, especially joeyoung inverter products, come with built-in diagnostic and monitoring features that alert you to issues such as lower efficiency, overheating, or overloading. When it is happening, you can troubleshoot the problem or seek a professional technician to repair or replace the inverter.
String inverter continuously monitors the performance of all solar panels and adjust the energy conversion process accordingly. If one panel produces less energy due to the shading, dirt, or another factor, the inverter compensates by adjusting the energy flow from the rest of the panels.
String inverters are designed to work under various weather conditions, but extreme weather such as heat waves, heavy rain, or snow can affect their performance. The string inverter is mostly built within weatherproof enclosures to protect the component inside. However, they should be installed in a proper space.
