If you are researching solar power systems, you may have heard of different types of solar inverters especially single phase and 3-phase inverters. Depending on your electricity supply (single-phase or 3-phase power) your decision might become simpler. In most Australian homes, the power supply is single phase, which means one live wire comes in from the grid. Single-phase power supply is commonly used in Australian homes while three-phase power supply pulls more power from the grid and is useful to handle bigger loads for large aircons, pools, heaters, electric car chargers, etc.
Contact us to discuss your requirements of solar inverter 3 phase. Our experienced sales team can help you identify the options that best suit your needs.
Most of the homes are connected to a single-phase power supply. Large homes, residential apartments and commercial buildings can have a 3-phase supply to manage the high electricity demand.
3-phase power is good to handle heavy loads from:
A single-phase solar inverter has one live wire which connects to your home. While a 3-phase solar inverter has 3 live wires connected to your home.
A 3-phase solar inverter sends the electricity evenly across the 3 wires which minimises the voltage drop problem associated with a single phase power supply. It needs to be noted that a 3-phase solar inverter will probably cost more than a single-phase inverter.
The ‘one-size-DOESN’T-fit-all-formula’ definitely applies to PV systems and solar inverters. There are currently a few different inverter types on the Australian market. But, ultimately, it comes down to how you want to use your solar energy, how much power you need, and what kind of solar installation you may already have.
We’ve already looked at string (or centralised) inverters, micro-inverters, and DC power optimisers in an earlier blog. Now it’s time to dig a bit deeper into the solar landscape to help you with your decision-making.
A hybrid inverter is your two-for-one deal. It allows you to connect a battery with your solar system and basically does everything a string - and a battery - inverter do.
The cost of a battery storage solution remains eye-watering in Australia. But as with so many innovative technologies, the demand will rise, bringing prices down. Even if you don’t intend to use battery storage right now, a hybrid inverter will still work. A hybrid inverter makes sense for new solar system installations, even if you want to use the battery function at a later stage only. It’ll save you additional installation costs in the future.
Another advantage is the easy monitoring of your energy consumption and production - it’s all in one central device. Plus, the solar panel inverter’s electronics will organise the charging and discharging of the battery. You won’t have to lift a finger.
Something to be aware of is compatibility with your battery storage solution. Of course, the easy way to work around this is to install the complete solar power system. On the Australian market, the Tesla Powerwall system dominates, and there are no known issues.
Want more information on what appliances can run on inverter? Feel free to contact us.
Consider that if you decide to add a hybrid inverter later on, you might have limited choices because of compatibility.
Will a hybrid inverter be the right choice for you? Discuss your requirements with us or ask for a quote.
Before we dive into the inners of a 3-phase solar inverter, let’s just unpack the terms 3-phase and 1-phase supply.
In this context, the definition ‘phase’ relates to the live wire coming in from the grid to a building. Most Australian homes have a single (one)-phase electricity supply.
A three-phase home has three live wires connected to the electricity supply. As a result, it can pull much bigger power loads from the grid to support heavy power users such as saunas, pool pump heaters, or an electric car charger.
If you’re not sure whether you are a 1-phase or 3-phase household, check your switchboard (better not touch anything, though!). The ‘poles’ on your meter isolator or main switchboard will tell you: 1-phase buildings will have one pole, and 3-phase buildings will have 3.
A 3-phase solar pv inverter will create balance in the power load. It converts solar DC power to AC power. It then feeds it evenly, over all three phases to your property and back to the grid, thus preventing a potential voltage overload. A 3-phase inverter is the most appropriate for larger-scale solar systems (6 kW and greater).
Depending on your power usage and the State or Territory you are in, one of the most significant advantages of a three-phase inverter is that you can send up to three times more solar energy back to the grid than you can with a single-phase inverter.
Having a 3-phase power supply doesn’t mean you have to use a 3-phase solar inverter though. In many cases, a single-phase solar inverter - or micro-inverters - will be perfectly fine, provided the system is smaller than 5kw.
A 5kw three-phase inverter is also slightly more expensive than a 5kw single-phase one. However, the three-phase option is a better choice if you have 3 phase power and are considering expanding your solar system in the future.
