Comparison to Microinverters

 

Module-level electronics overcome the shortcomings of traditional inverters and enable maximum power, module-level monitoring, flexible design and enhanced safety. However, there is no need to add an inverter to every module if DC power optimizers can achieve all these benefits at lower cost, higher efficiency and higher reliability.

A Comparison of Microinverters & Power Optimizers



Benefits


Microinverters

SolarEdge
Power Optimizers


 Details


Low Cost / W


X X

 

  • On an average system, Microinverters will cost twice as much as a comparable solution powered by SolarEdge


Scalability


X

 

  • The cost per watt of a SolarEdge system decreases as installation size increases lowering costs further



Added Energy

 

 

 

 

  • Power optimizers have a lower minimum voltage requirement than micro inverters meaning that they have greater shade tolerance




Compatibility




X

 

 

 

  • The leading Microinverter only supports 60 cell modules and 240W.SolarEdge supports nearly all name brand modules up to 400W and supports 2-to-1 connection of modules on commercial systems up to 700W




Temperature Resistance






X

 

 

 

 

  • Although in the same environment, the leading micro inverter is only resistant to 150°F, that’s 35°F less than the module rating of 185°F.  SolarEdge power optimizers are resistant to the same 185°F



Reliability

 


X

 

 

  • The leading Microinverter uses twice as many parts with shorter lifetimes. SolarEdge uses fewer parts and uses solid state electronics that are more reliable on the rooftop
