Types, Technology & What You Need to Know

If you're investing in a solar power system, the solar inverter is one of the most important components to understand. In simple terms, it converts the DC electricity generated by your solar panels into AC electricity, which powers your home or business. Whether you're installing a residential rooftop system or a large-scale commercial array, choosing the right inverter is critical for performance, efficiency, and long-term reliability.

Types of Solar Inverters

At Yello Energy Group, we install and service all major types of inverters to suit every energy need. Here’s a breakdown:

1. Grid-Tied Inverters (On-Grid)

These are the most commonly used solar inverters in homes and businesses connected to the electricity grid.

Convert solar energy for immediate use and export excess power back to the grid.
Enable feed-in tariffs or net metering for savings on electricity bills.
Cannot operate during blackouts unless combined with battery storage and backup features.
Best for: Households and businesses looking to save on energy bills while staying connected to the grid

2. Off-Grid Inverters

Designed for complete independence from the electricity grid.

Stores and manages power from solar panels and batteries.
Requires a battery bank and often a backup generator.
Includes built-in charge controllers and robust load management features.
Best for: Remote properties, rural farms, and anyone wanting complete energy independence

3. Hybrid Inverters

A flexible option that combines the benefits of grid-tied and off-grid systems.

Manages power from solar panels, batteries, and the grid.
Seamless blackout protection and energy storage capability.
Ideal for homes or businesses planning to install batteries now or in the future.
Best for: Future-proof solar systems with storage and grid interaction.

4. Microinverters

Unlike string inverters, microinverters are installed behind each solar panel.

Converts power at the panel level, improving performance on shaded or complex roofs.
Increases system reliability — one panel’s shading won’t affect the rest.
More expensive but offers detailed monitoring and higher yields.
Best for: Homes with partial shading, multiple roof orientations, or aesthetic design considerations.

Inverter Technology Explained

Understanding inverter specs can help you make an informed choice. Here are the key tech features we consider when designing your solar solution:

Maximum Power Point Trackers (MPPTs)

MPPTs optimise the voltage and current of solar panels for maximum output.
More MPPTs = better handling of shade, orientation differences, or split arrays.
Residential inverters typically include 2 MPPTs; commercial units may have 4–10+

Inverter Efficiency

Expressed as a percentage — the higher, the better.
Top-tier inverters today offer 98% to 99% conversion efficiency.
Higher efficiency means more of your solar power is usable.

Safety & Compliance

Built-in safety features like:

Anti-islanding protection
Over-voltage and surge protection
Emergency shutdown (Rapid Shutdown ready)
All inverters installed by Yello Energy Group meet the Clean Energy Council (CEC) standards and comply with Australian regulations.

Voltage and String Sizing

Must be properly sized for your solar panel configuration.
Residential systems often run at 150–600V DC; commercial up to 1500V.
Correct string sizing ensures optimal performance and inverter lifespan.

Cooling Systems

Passive cooling: silent and reliable, but may reduce performance in extreme heat.
Active cooling: includes fans or heat sinks to maintain efficiency under high loads.

Monitoring and Smart Features

Most inverters come with built-in Wi-Fi or Ethernet connections.
Access your system performance in real-time via mobile apps or a web dashboard.
Receive alerts for faults, production trends, or energy usage.

Why Inverter Choice Matters

A high-quality solar inverter enhances system performance, protects your investment, and maximises long-term savings. At Yello Energy Group, we partner with leading inverter brands like Sungrow, Fronius, GoodWe, Solis, and more — ensuring you receive a system that’s efficient, compliant, and built to last.
