Regarding the above single-phase and three-phase models, which will be your choice?
Single-phase & three-phase systems:
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.
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.
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.
In a three-phase system, 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.
What is single-phase?
In a single-phase AC power system you’ll see two wires that carry the electrical current. These are the phase wire (sometimes called a line or hot, or live wire) which delivers the current to the load, and the neutral wire which returns it back to its source. Depending on where you live, the voltage is usually 230V, at a frequency of 50 Hertz.
Single phase power supplies are therefore the usual choice when the loads consist of lighting or heating, and don’t have to service large electric motors.
But you can’t run any heavy loads like industrial motors or heavy-duty equipment on a single-phase supply. Nor can you start up a small (less than 1kw) single-phase motor directly using a single-phase supply, because it won’t generate sufficient initial torque to get the motor turning. So, to use a single-phase supply for heavier loads, you’d need something like a motor starter or a variable frequency drive to make them work properly.
What is three-phase?
In a three-phase system, you’ll find three or four wires that transmit the current. If there are only three power wires, all three of them are phase wires, with each power signal being delivered 120° out of phase with the other two. In a three-phase system, it is possible to split it into three separate single-phase circuits, which is not the same as a direct three-phase supply.
In a three-phase power supply, the voltage generated between any two phases is 415V, and 240V between a phase and neutral. The current goes in cycles of 360°, so that each phase reaches peak voltage twice in one cycle. The main advantage of this is that the power supply is continuous, and never drops out entirely. This constant stream of power, plus the three-phase system’s ability to accommodate higher loads, are what makes three-phase so well suited to commercial and industrial operations.
Designed for large homes with three-phase power and high energy consumption, the Tewaycell three-phase system will allow you to use more of your self-generated power to reduce your power bills. Achieve even higher levels of self-sufficiency by relying less on your energy retailer with our all-in-one three-phase system.Refer to 20kwh all-in-one
Why choose Tewaycell?
The Tewaycell single-phase or three-phase system seamlessly integrates solar inverter and battery storage into a single, elegant unit. Unlike the conventional approach of installing these components separately, our all-in-one system eliminates the need for unsightly excess cables connecting them. This not only enhances safety but also improves the overall aesthetics of your solar storage.
