• • What is a 3-phase power supply?To understand 3-phase solar, you’ll need to be familiar with 3-phase power supplies. The power supply is the connection point that your home has to the grid and it generally comes in two forms: single and 3-phase. 3-phase, as the name suggests, uses three active wires and one neutral to transmit electricity from the grid to your appliances. In comparison, single-phase only uses one active and one neutral wire.Single-phase power supplies are most common among residential properties in Australia, with 3-phase being reserved for larger homes and commercial properties. However, you may find some older homes will have a 3-phase power supply.
    

    What’s the difference between 3-phase and single-phase power supplies?

    The main difference between a single-phase and 3-phase power supply is the number of wires used to transmit electricity from the grid to a property. As the names suggest, a single-phase connection will use just one live wire, whereas 3-phase incorporates three active wires.

    3-phase power supply is generally better equipped to handle bigger energy loads, as it has the capacity to draw more power from the grid due to the additional wires. This is why this connection type is more common in commercial properties that tend to consume energy at a higher capacity. But 3-phase power can be useful for homes that operate large appliances such as heaters, pool pumps, spas or electric vehicle chargers.

    With a 3-phase power supply, electricity distribution is essentially divided among the three wires, meaning that certain appliances may only be powered by certain wires. For example, your dishwasher and washing machine may be powered by one supply, while your home appliances run on another. On a single-phase connection, all household power is supplied through the single wire.

  Whether you should install a 3-phase solar system will depend on your property’s power supply. If you have a single-phase power supply, you will need to install a single-phase solar inverter and system. This is because a single-phase power connection cannot absorb and transmit power from three different supply points.

  If you have a 3-phase power supply, you can install either single or 3-phase solar. Typically, 3-phase power supply is separated across three mains, which means that certain appliances will only be powered by certain wires. However, you have the option to install a single-phase inverter on just one power supply so the appliances on that connection run on solar. Excess solar from this supply can still be diverted to the other two connections through the use of a bi-directional meter (which is generally installed with your solar), before being sent to the grid in exchange for a solar feed-in tariff (FiT).

  Be aware that installing a single-phase solar inverter on a 3-phase power supply could impact the voltage on your system. This is due to single-phase inverters having a lower capacity than 3-phase connections, meaning it has to work much harder to transmit the solar power to be used. As a result, a single-phase inverter may trip more frequently than it would if it were 3-phase.
