Single-phase inverter

Are you looking for a single-phase inverter for your photovoltaic installation? Planet Soar, specialist in energy transition, offers you a selection of quality products at reasonable prices.

What is a single-phase inverter? 

A single-phase inverter is a device connected to your photovoltaic panels. Its role is to convert the direct current produced by the panels into alternating current. This current can then be used by your electrical appliances. This equipment is compatible with a single-phase electrical installation. 

A single-phase installation is based on a single electrical phase. This is the most common installation in households. It corresponds to a power level of between 1.5 kVA (kilovoltampere) and 12 kVA. 

What is the difference between a single-phase inverter and a three-phase inverter?

The three-phase inverter differs from a single-phase model in that it is adapted to a three-phase electrical installation. This configuration is often necessary for businesses with professional or industrial machinery requiring high levels of electrical power. It can also be used in homes with a meter located a long way from certain points in the home. 

How does the single-phase inverter work?

The solar inverter connected to the solar panels converts the current into electricity. The current generated by your solar panels is direct current. As it is, it cannot be distributed to your installation.

The single-phase inverter contains electrical components that transform it into direct current. These control the voltage and allow the alternating current to be injected into your electrical system.

Advantages and disadvantages of a single-phase inverter?

This solar equipment has many advantages. The single-phase inverter is compatible with most residential electrical installations. It is therefore suitable for solar panels serving a domestic installation. 

This type of inverter is highly efficient, generally exceeding 95%. It can therefore convert most of the energy produced by photovoltaic panels. What's more, it's easy to install and requires no special maintenance. 

There are a few drawbacks to its use. It has limited power, unlike a three-phase inverter. While this is sufficient for domestic installations, it is not suitable for large-scale photovoltaic installations. Incorrectly dimensioned inverters can create stability problems on the grid. To avoid these, you need to choose the right power.

How do you choose a single-phase inverter?

A number of criteria need to be taken into account when choosing your single-phase inverter: 

• The power required to supply your installation; 
• The percentage efficiency: 
• The manufacturer's warranty; 
• The ease of installation; 
• The built-in electrical protection; 
• The options available, such as an integrated WLAN module.

FAQ

Which is the best single-phase inverter for my installation?

The best single-phase inverter is the one that meets your needs. You therefore need to know your requirements in terms of electricity consumption and the characteristics of your solar panels. The rated power of the inverter should correspond to 80% of the overall peak power of your electrical installation.

Can you install an inverter yourself?

Single-phase inverters are the easiest to install. However, you will need a good knowledge of electricity to ensure the safety of your installation. If in doubt, contact a professional.

How much does a single-phase inverter cost?

The average price of a single-phase inverter is between €300 and €1,500. It all depends on its power and characteristics.
