Three-phase inverter

Are you looking for an inverter that is compatible with your three-phase electrical installation? Do you need to invest in a three-phase inverter for your solar panels? Planet Soar, the energy transition specialist, will help you find the right product for your needs. 
 

What is a three-phase inverter?
 

A three-phase inverter is a solar inverter whose role is to transform the direct current produced by a photovoltaic panel into alternating current. In this way, it can power your various appliances. This inverter is designed to be compatible with a three-phase electrical installation. 

What is a three-phase power supply? A three-phase power supply is made up of 4 cables. These are 3 phase conductors and a neutral cable. This type of installation is designed to produce three times the voltage of a single-phase system. The power required at the meter exceeds 18 kVa (kilovoltampere). 

Three-phase current is reserved for energy-intensive structures. For example, businesses that use professional machinery or tools, or homes with outbuildings. The three-phase inverter can handle solar installations connected to this type of current.
 

How does a three-phase inverter work?

This inverter is capable of creating voltage pulses in 3 distinct phases using its electronic switching components (transistors or thyristors). It receives a DC input voltage from the solar panel. It then converts it into alternating current using modulation techniques:

 

 

• Pulse width modulation (PWM) adjusts the amplitude or duration required for each phase. 
• Frequency modulation (FM) is used to obtain the appropriate output frequency.

 

What's more, the inverter can optimise energy production with the Maximum Power Point Tracker (MPPT) function. 
 

What are the advantages of a three-phase inverter?
 

The three-phase solar inverter has a number of advantages: 
 

• Balanced distribution of the electrical load over the 3 phases: This avoids any overloading problems and ensures stability of frequency and voltage. This stability is important for protecting equipment, particularly in an industrial context.
• Greater energy efficiency: the balanced distribution of current across the different phases improves the yield of the photovoltaic installation. The three-phase inverter is therefore ideally suited to commercial or industrial installations requiring substantial power.

What criteria should I take into account when choosing a three-phase inverter?
 

To ensure that the inverter meets your needs, the following criteria should be taken into account: 
 

• The power required for your installation;
• The equipment's output power; 
• The device's regulation and protection features; 
• The inverter's energy efficiency; 
• Its ease of installation and maintenance;
• The manufacturer's warranty; 
• The options available, such as an integrated WLAN module for monitoring system performance. 

 

How much does a three-phase inverter cost?

 

The cost of a three-phase inverter varies according to its characteristics. On average, it costs between €500 and €2,000. At Planet Soar, we offer you quality photovoltaic products at affordable prices to make the energy transition accessible.
