Hello, It's hard to tell what might be causing the difference without seeing all of your code. There is a quick way to compare SAM results with results via the SSC API. Each time you run a simulation in SAM, it creates a set of scripts in each of the...

We do not have a guide for adding inverters to the CEC library for SAM's "Inverter CEC Database" inverter model, mostly because we do not expect most people to have the test data to be able to do so. If you do have the data for one or more inverters,...

Hello, I would like to use SAM with custom weather data. To do so, I have first copied a sample CSV file from the library. When I use the copied file unedited, the simulation proceeds normally. When I open the file with Excel and save it as a CSV even...
