Solar PV String Inverters
City Plumbing sells a superb selection of solar PV string inverters. String inverters are a popular and cost-effective option for solar systems, especially on roofs with minimal shading and a consistent orientation. With a good lifespan, these devices are ideal for generating electricity for a home or a business.
What Are Solar PV String Inverters?
A solar PV string inverter is a type of inverter that converts the direct current (DC) electricity generated by a series of solar panels (a "string") into usable alternating current (AC) electricity. Instead of having an inverter on each panel, a string inverter is a single, centralised unit that handles the power conversion for a group of panels.
How Do Solar PV String Inverters Work?
Solar panels are wired together in a series to create a string. The panels in a string produce DC electricity, which is then sent to a single string inverter. This inverter, usually located on a wall near the solar array, takes the combined DC power and converts it into AC power, which is what homes and businesses use. Some larger string inverters can handle multiple strings of panels.
What Are The Benefits of Solar PV String Inverters?
- Cost-effectiveness: String inverters are generally the least expensive type of inverter, making them a popular choice for homeowners and those on a budget. Because a single unit handles the conversion for multiple panels, there's less hardware to purchase.
- Simpler Installation and Maintenance: With only one or two inverters to install and maintain, the process is less complex and requires fewer labor hours. If a problem arises, troubleshooting is easier since the inverter is typically installed on the side of a building, not on the roof.
- Proven Technology: String inverters have been used for decades and are a well-understood, reliable technology.
- High Efficiency: Modern string inverters have high-efficiency ratings, often converting DC to AC at rates of up to 98%.
Are String Inverters Suitable for My Solar System?
String inverters are a great choice for simple, unshaded roofs where all the panels face the same direction. If your roof has multiple orientations or significant shading, other options like microinverters or power optimisers may be a better fit to maximise energy production.
How Long Do String Inverters Last?
The lifespan of a string inverter is typically between 8 to 12 years, which is shorter than that of the solar panels themselves. This means you will likely need to replace the inverter at least once during the lifespan of your solar array.
Can I Expand My Solar System with a String Inverter?
Expanding a system with a string inverter can be challenging. Since the inverter is designed for a specific number of panels and a certain power capacity, adding more panels often requires installing another inverter, which adds to the cost and complexity.
What’s the Difference Between a String Inverter and a Microinverter?
A string inverter is a single, centralised unit for a group of panels, whereas a microinverter is a small, individual inverter attached to each solar panel. Microinverters offer panel-level optimisation, meaning a problem with one panel doesn't affect the other
