Solaredge Inverter System Question was created by timbobster21
Does SAM model the efficiency curves of both the inverter and the optimizer for a Solaredge system?
Why is there not an option to select the optimizer that is being used? Will this be added in the future?
Please advise on current methods and future solutions for module level electronics.

Hello,
For now, SAM's flat-plate photovoltaic model does not explicitly model DC power conditioning equipment. SAM assumes that the modules in the array operate uniformly because it calculates the array's total output by multiplying the output of a single module by the number of modules in the the array. You account for module mismatch and other losses on the DC side of the system using the "pre-inverter derates" on the PV Subarrays page. The default value of these DC derate factors are for a system with no DC power conditioning equipment, so if you are modeling a system that minimizes DC losses, you can adjust these derate factors accordingly.
If you are interested in our plans for future development of SAM, you can download the SAM Work Plan for FY 2015 from the About page of the SAM website . Subtask 2.3 describes the proposed work on developing models for DC-DC optimizers in SAM.
Best regards,
Paul.

This document covers many of the derates and shows how to calculate them with SolarEdge:
