Understanding three-phase supply
If you’re looking to combine your solar system with a battery for your home or business, one of the first things you need to know is if your home has a single phase or three-phase supply.
• Single-phase supply
If you have a single-phase supply, there is one active wire and one neutral wire fed into your home.
• Three-phase supply
In case of having three-phase supply, there are three active wires feeding into your home and one neutral.
How do you know if you have single or three-phase power?
The simplest way to check is:
- Go to your meter box
- Carefully look in your switchboard (don’t touch anything!)
If you have three main switches, you have three-phase power supply. If you only have one, you have single-phase power supply. It’s as simple as that.
In the past, most homes had a single-phase electrical connection. This used to be sufficient, because electrical requirements were comparatively basic. Back then, lights, a refrigerator, and a television pretty much covered it.
Nowadays, almost everything we interact with relies on being plugged in. Your phone, computer, air conditioner, dishwasher, gaming console, washer dryer, oven, plus a whole plethora of other electronic devices: they’re all power-hungry. This isn’t to mention the rise in popularity of electrical vehicles!
This lifestyle change, then, has led to the rise of three-phase power in homes. And we’re not just talking about new homes being built. Today, an increasing number of homeowners are investing in upgrading their electrical connections to three-phase to meet growing demand.
Single-phase vs. three-phase inverters
So, what is a three-phase inverter and how does it operate?
An inverter is the device responsible for converting the direct current (DC) power generated by sources like solar panels into alternating current (AC) power — suitable for use in homes, businesses, and industrial applications.
A three-phase inverter distinguishes itself by transforming DC power into three separate AC waveforms. This configuration is tailored to three-phase electrical systems. These systems are renowned for their enhanced efficiency, reliability, and capacity to handle larger loads compared to single-phase counterparts.
Single-phase inverters, on the other hand, generate a single AC waveform. While they are well-suited for smaller-scale installations, their limitations become apparent in larger setups.
Three-phase inverters, with their three distinct AC outputs, deliver more consistent power distribution. And, in turn, they facilitate the seamless operation of multiple electronic devices and machines.
Benefits of three-phase inverters
· Higher power output
As mentioned previously, three-phase inverters can transmit more power than single-phase models. This becomes essential when you need more power to keep all your electrical devices (such as dishwasher and electrical vehicle) powered at once.
· Improved efficiency
One of the standout advantages of three-phase inverters is their remarkable efficiency. By spreading the electrical load across three phases, they reduce the risk of overloading any single phase.
In turn, three-phase inverters optimise power generation and distribution. This enhanced efficiency translates not only into energy savings, but also extends the durability of electrical equipment — reducing long-term maintenance costs.
· Reduced energy costs
Efficiency translates into lower energy costs. With a three-phase inverter, you can maximise energy production while minimising dependence on the grid.
This makes three-phase inverters an attractive option for businesses or properties with high energy needs looking to reduce their operational expenses.
· Better voltage regulation
Three-phase inverters provide better voltage regulation than single-phase models. This means that they can help ensure that your appliances receive a consistent, reliable supply of electricity.
