The basics of solar inverters

Inverters are important for your solar panels because they convert Direct Current (DC) electricity to usable Alternating Current (AC) power. Hence, choosing the right one is vital for system performance.

There are different types of inverters today. String inverters follow a traditional setup in which panels are connected in a “string,” feeding DC power to a central inverter. This is a cost-effective solution suitable for simple installations without shading. However, performance may be significantly impacted by shading on even one panel.

Another type is the micro inverter, where each panel has its dedicated inverter. The good thing about this type of inverter is that it can maximise energy harvest even with partial shading. The downside? It has a higher upfront cost.

Finally, hybrid inverters combine solar conversion with battery management. It allows battery storage for backup power and increased self-consumption. This is also one of the reasons that a hybrid inverter comes with the highest upfront cost among these types of inverters.

Solar inverter explained: The heart of a solar power system

In simple terms, a solar inverter converts the direct current (DC) electricity produced by solar panels into alternating current (AC) electricity, which powers most household and commercial appliances. Solar panels absorb sunlight and generate DC power, but Australian homes and businesses require AC power. The solar inverter bridges this gap, allowing the solar energy captured on rooftops to directly power lights, appliances, and other electronic devices.

A solar inverter is essential for energy conversion, system monitoring, and safety. Advanced inverters monitor energy production, track the system’s performance, and even help detect issues or faults, alerting users if maintenance is required.

How does a solar inverter work?

Solar panels absorb sunlight and convert it into DC electricity. This DC power is then fed into the solar inverter, which performs the following steps:  

1. DC to AC conversion: The solar inverter employs sophisticated electronic circuitry to rapidly switch the DC power on and off, creating a sine wave pattern that mimics AC power.  
2. Voltage and frequency adjustment: The solar inverter regulates the voltage and frequency of the AC power to match the grid’s standards, ensuring seamless integration with the electrical grid. 
3. Power optimisation: Many modern solar inverters feature advanced algorithms like Maximum Power Point Tracking (MPPT) to maximise energy output from solar panels, even under varying sunlight conditions.

Types of solar inverters: Choosing the right one for your needs

There are various solar inverters on the market, each with unique features, benefits, and ideal applications. Knowing the differences helps users select an inverter that best matches their needs and environmental conditions.

1. String Inverters

String inverters are the most commonly used in residential and commercial solar installations. In a string inverter system, multiple solar panels are connected in series to form a “string,” which is then connected to the inverter. This setup works best when solar panels have the same orientation and minimal shading.

String inverters are known for their cost-effectiveness and simplicity. However, their efficiency may reduce if part of the array becomes shaded, as shading on one panel can affect the performance of the entire string.

2. Microinverters

Microinverters are small inverters installed on each solar panel. Instead of simultaneously converting power from multiple panels, each panel’s energy is converted independently. This system is ideal for rooftops with shading issues or complex layouts.

While microinverters are generally more expensive than string inverters, they can significantly improve inverter efficiency for solar in shaded or challenging installations. Microinverters also allow for panel-level monitoring, giving users detailed insights into each panel’s performance.

Introduction to microinverters

Microinverters have emerged as a popular choice for homeowners and business owners in Australia seeking to harness solar energy. 

What are microinverters?

Microinverters work at an individual panel level, converting each panel’s DC (direct current) electricity generated into AC (alternating current) electricity usable by households and businesses. 

Think of each solar panel on your rooftop as a mini power station—optimising its output independently of shading, debris, or degradation. Decentralising the conversion process ensures maximum energy production from each panel. This results in higher overall system efficiency and greater energy harvest, specifically where panels are subject to variable conditions throughout the day. 

Aside from efficiency, microinverters enhance safety by minimising the risk of system-wide shutdown due to issues with a single panel. It also facilitates easier system monitoring and maintenance. It becomes easier to identify performance issues with a microinverter, which helps in better optimisation of solar systems. 

Key features of microinverters

• Individual panel optimisation: Each microinverter operates independently, maximising the output of its corresponding solar panel.
• Modular design: Microinverters allow for easy system expansion, accommodating additional solar panels without significant redesigns.
• Real-time monitoring: Advanced monitoring capabilities enable homeowners to track the performance of each panel.

How microinverters work

Microinverters convert DC electricity produced by individual solar panels into usable AC electricity. Unlike traditional string inverters, which manage multiple panels collectively, microinverters operate at the level of each panel, allowing for independent optimisation of energy output. 

Each microinverter is installed on or near its respective solar panel and performs the conversion process directly at the source of generation. This means that the DC electricity generated by each panel is immediately converted into AC electricity, minimising power losses associated with long cable runs and ensuring optimal panel performance.

Microinverters vs. string inverters vs. power optimisers: A comparative analysis

Microinverters

• Best for: Systems with shading issues or panels installed at varying angles.
• Pros: Panel-level optimisation, enhanced reliability, and modular scalability.
