What is an inverter with a transformer?
An inverter with a transformer is a crucial component in a photovoltaic system. Unlike inverters without a transformer, these devices use a physical transformer to convert the voltage from direct current (DC) to alternating current (AC). This process is necessary to feed the generated solar power into the grid.
What is the difference between an inverter without and with a transformer?
The main difference lies in the type of voltage conversion. Inverters without a transformer use electronic circuits, while inverters with a transformer use a physical transformer. The transformer allows for precise adjustment of the voltage to the grid conditions.
Advantages and disadvantages of inverters with a transformer
Advantages:
- Robustness: Inverters with a transformer are often more robust and resistant to voltage fluctuations in the grid.
- Cooling: The transformer allows for natural cooling, which protects the inverter from overheating.
Disadvantages:
- Weight: Inverters with a transformer are generally heavier and larger.
- Efficiency: Due to transformation losses, inverters with a transformer may have a slightly lower efficiency.
Special Features of Inverters with Transformers
Inverters with integrated transformers, also known as transformer-based inverters, represent an important variant in photovoltaic technology, distinguished by their specific properties from transformerless models. In the PV wholesale market, you will find both technologies for different application areas.
The central advantage of inverters with transformers lies in the galvanic isolation between the direct and alternating current circuits. This electrical insulation increases the safety of the entire system, as there is no direct electrical connection between the DC circuit of the solar modules and the public AC grid. This can effectively prevent potential disturbances and equalizing currents.
Transformer-based inverters show particular strengths under demanding operating conditions. They offer greater robustness against grid disturbances and voltage spikes, which can be advantageous in regions with unstable grid conditions. They are also suitable for thin-film modules, which often require grounding of the negative pole to prevent corrosion effects.
The built-in transformer ensures optimal adaptation of the input voltage to the required grid voltage. This allows for more flexible use with different module configurations and can be advantageous in complex systems with different voltage levels.
However, transformers also bring additional weight and volume. The electromagnetic conversion also creates losses in the form of heat, which slightly reduces the overall efficiency compared to transformerless inverters. In practice, transformer-based inverters typically achieve slightly lower efficiencies.
Despite these disadvantages, transformer-based inverters remain the preferred choice for certain applications, especially when there are increased safety requirements or when special module technologies are used. In the solar wholesale store of pvXchange, you will receive expert advice on which inverter technology is best suited for your specific requirements.
