Which inverters can be used with DualSun SPRING & FLASH panels?

When choosing the inverter that will transform the DC electricity (direct current) of the DualSun panels into AC electricity (alternating current), it is important to check that it is compatible with the panel. A panel is compatible with an inverter as long as the ranges of voltages and intensities that it can deliver are included in the operating ranges of the inverter, this ensures that there is no risk of damaging the inverter.

Generally, centralized inverters (for projects > 100 kWp) or string inverters (for projects < 100kWp) are compatible with our panels and you can size them on the inverter manufacturer's website by choosing our panels in their software. 


Choose a centralized inverter

To choose your centralized inverter, it is important to know the characteristics of your solar  field:

  • Total peak power of the installation (Wp)
  • Open Circuit Output Voltage (Voc)
  • Short-circuit output current (Isc)

The open-circuit voltage (Voc) is the maximum output voltage of our installation, it depends on the number of panels in series on each string.

The short-circuit current (Isc) is the maximum current at the output of our installation, it depends on the number of strings in parallel on our installation.

These values should be compared with the “Voc max” and “Isc max” values of the centralized inverter data sheet.


Choose a Microinverter or Optimizer

The approach is identical with the choice of a centralized inverter with the difference that the Voc and Isc to check corresponds to the characteristics of a single panel (not to the complete system).

If you use micro-inverters or optimizers, however, it is important to confirm compatibility with our panels. The installers of our partner network will fully advise you on the most suitable equipment for your project.

Here is the non-exhaustive list of micro-inverters and optimizers compatible with our DualSun SPRING and FLASH panels

NB : This table is given as an indication,it is necessary to check the compatibility with the manufacturer of the microinverter or optimizer. They should be able to accompany you on the terms and limitations of use of their products, notably through the product manuals.


Solar Clipping

Solar clipping is a limitation of the output power of the inverter. It occurs when the output power of the photovoltaic panel exceeds the maximum output power of the inverter. In case of solar clipping, the daily power curve of the inverter can be flattened during the peak production hours.

In our compatibility table, we have differentiated several types of compatibility:

  • Not compatible: the operating limits of the inverter can be exceeded.

  • Compatible: the voltage and current of the panel will always be within the operating range of the inverter.

  • Compatible but may experience clipping at NOCT: the voltage and current of the panel will mostly be within the operating range of the inverter, and it is possible that under optimal and realistic production conditions, power clipping may occur. In practice, these optimal conditions are rare, and the impact of power clipping on a year of production is often negligible. To be sure, a financial study can be conducted to determine if the loss caused by power clipping outweighs the benefit of purchasing a more powerful and more expensive micro inverter.
