PVWatts is an online simplified modeling tool to calculate PV system performance based on the array’s geographic location, orientation and other inputs.
While the default settings for PVWatts are designed to represent central inverters, with some modifications the tool can also be used to model optimized inverters.
NREL’s document Modeling Microinverters and DC Power Optimizers in PVWatts provides some guidelines for this process.
We’ve shared a handy table from the guide to get you started. See a full example of using the tool to model SolarEdge optimized inverters at solaredge.us/articles/blog.
