If You Have Three-Phase Power, Do You Need a Three-Phase Inverter?

Lots of Australian homes have a single-phase power supply, which indicates they have one live wire coming in from the grid. Some houses, nevertheless, have a three-phase supply, with 3 live wires pulling power from the grid.

A three-phase home can pull more power from the grid, which works if your house requires larger loads such as large a/c, pool heating systems, electric cars, and truck battery chargers.

A three-phase solar inverter takes in Direct Current from solar panels, transforms it, and sends AC power through the house uniformly across 3 phases. These inverters typically look like single-phase inverters, although they usually have a higher cost.

Three-phase solar inverters are perfect for larger solar inverter systems, as it prevents having too much load being sent out on single-phase, which could cause an imbalance in between the loading of all phases. However, this is typically a factor to consider for larger solar systems, and not a lot for 5kW capacity or fewer inverters, as 5kW of power going through one phase will normally not trigger any issues.

To examine if you have a three-phase supply, all you require to do is search in your switchboard. You will see only one ‘pole’ on your primary switch or meter isolator. If you have a single-phase supply, you will see 3 ‘poles’ If you have a three-phase supply. This may sound easier to say than to do, as it might be tricky to recognize the elements on a meter box if you don’t have the knowledge of an electrician. If this is your case you can just send a picture to your electrician and they will tell you if it’s single or three phases. At AYKA SOLAR we help our customers by giving them accurate information after they send us their meter box pictures

A three-phase inverter can produce three-phase power from the solar energy system and can be connected to three-phase equipment or a grid. A three-phase inverter converts the DC input from solar panels into three-phase AC output. Usually, a three-phase inverter is preferred if a three-phase power source is used in the installation location; a single-phase inverter is also used for single-phase sources and is the most common of the two types. The three-phase solar inverter means you can produce more power for direct use and also send much more solar energy back into the grid compared to the single-phase.

If your house has a three-phase supply, we strongly recommend a three-phase inverter. There are many benefits of using three-phase solar inverters. Primarily as mentioned above, these inverters will help avoid imbalances in the power loading. Then, whenever the inverter capacity is spread across three wires, it would be easier to push the solar energy back to the grid. if you use a single-phase inverter, on a three-phase supply then you will be able to use solar power only for that single-phase, and the remaining two phases will continue using grid power.

The best way to find out if you need a one-phase inverter or three-phase solar inverter is to find an experienced solar company and speak with their team of solar experts. At AYKA Solar, we will do a site inspection to check your home and power consumption, and will you require a single-phase or three-phase solar inverter.
