The role of solar inverters

Inverters are not merely about converting currents; they are about harnessing potential. They take the DC output from solar panels and transform it into AC electricity, the standard used by most home appliances and the power grid. Without inverters, solar energy would remain a latent resource, unutilized and unappreciated.

The spectrum of inverters

Solar inverters come in various shapes and forms, each with its unique capabilities and suited for different scenarios:

String Inverters: The most common household choice, these single units connect to a ‘string’ of solar panels. They excel in setups where sunlight is abundant and unobstructed. However, their Achilles’ heel is shading; even a shadow on one panel can diminish the output of the entire string.

Microinverters: These are the precision instruments of solar inverters, attached to each panel, allowing for detailed monitoring and mitigating the ‘all-or-nothing’ drawback of string inverters. If one panel is shaded or underperforming, the rest of your array remains unaffected.

Battery-only Inverters: For systems where energy storage is retrofitted to an existing panel array.  Retrofitting with a battery-only inverter is a practical choice. It ensures that excess energy isn’t wasted but stored for future use.

Hybrid Inverters: The all-rounders of the inverter world, hybrids combine the capabilities of string and battery inverters. They’re an excellent match for those planning a future-proof system that may include energy storage.

Single vs three phase systems – the basics

A single-phase system is the most common type of electrical system found in homes, as it is simple, easy to install, and sufficient for most homes. 

Three-phase systems have three electricity inputs coming into the home and are typically used in commercial properties, or in larger residential properties with high energy demands like heavy machinery or other heavy duty appliances.Read more about single phase & three phase in our blog here.

Does it matter what type of connection to the grid I have when choosing a solar system for my property?

In short – a single phase solar battery and inverter works without problems in a three-phase grid connected home so you don’t need to worry about forking out extra $$ for a three phase inverter/battery combo. 

In a single-phase system, a solar panel and battery system is connected to the grid through a single-phase inverter, which converts the DC electricity produced by the solar panels or stored in your solar battery into electricity to power your home. 

In a three-phase property, a solar panel and battery system can also be connected to the grid through either a single-phase or three-phase inverter. The difference is that in a three-phase home the inverter is responsible for balancing the power between the three phases, which is necessary to ensure that the heavier energy load is distributed evenly to your home, or back into the grid if you are on a VPP connected to the grid.

Selecting the right inverter

Choosing an inverter isn’t just about picking a type; it’s about envisioning your energy future. Will your panels bathe in uninterrupted sunshine, or does shading come into play? Are you contemplating energy storage down the line? Your answers will guide your choice. 

The good news is that this is not something you need to work out yourself. Your ShineHub solar consultant will help you identify the right option.  And don’t forget to consider warranties – they’re an important part of your inverter investment. The great news is that the AlphaESS SMILE S5 battery and integrated hybrid inverter comes with a rock solid industry leading 10 year warranty, giving you peace of mind and long term protection.

Why inverters should be viewed as the brains of your whole solar system

An inverter isn’t just a component; it’s the interpreter between your solar panels, battery, the energy grid, and our innovative ShineHub Virtual Power Plant, helping to manage and fulfil your energy needs. A well-chosen inverter maximizes your system’s output, ensures operational reliability, allows you to influence how your system behaves (for example you could set up grid charging for your battery during off peak for example), and provides insight into your energy habits with monitoring capabilities.

Conclusion – the future of inverters

As we embrace the electrification of our lifestyles, the role of inverters becomes ever more critical. Their ability to integrate with Virtual Power Plants (VPPs) and adapt to evolving energy demands signifies their importance not just in our homes, but in the broader energy landscape.
