DC Optimizer

Paul,

I have a goal of producing a script which calculates an efficiency value for Tigo/Solaredge optimizers and inputs it into the DC nameplate derate in the model. These products are gaining traction in the marketplace, is there anyone else that you know of who has worked on something like this? I will create a script for this rather than using a wrapper this time around. I like that the 'new' scripting language is able to use the SSC.

Thanks,

Jonathan Topham

Dear Jonathan, This recent NREL publication makes recommendations of loss values to represent module-level power electronics (microinverters and DC power optimizers) for PVWatts that should be useful for your work:
MacAlpine, S.; Deline, C. (2015). Modeling Microinverters and DC Optimizers in PVWatts. National Renewable Energy Laboratory. TP-5J00-63463. ( PDF 360 KB )
Best regards,

Paul.
