The Top 10 Most Common Myths about Traditional DC Power Optimizers: Part 3 of 3

by Blair Reynolds (guest post), , 19 Comments

DC Power OptimizersNow that we’ve explored the top ten common myths of traditional DC optimizers, you’re probably thinking, “OK then, what makes SMA’s ShadeFix optimization so much better?” Before we get into that, here’s a recap of the top ten myths in case you’d like a refresher:

Myths 1-5
  1. Power Optimizers generate more energy for shaded PV arrays
  2. Traditional Power Optimizers generate more additional energy than they consume
  3. Power Optimizers (or microinverters) are required for Code Compliance
  4. Power Optimizers detect ‘failed’ PV modules
  5. Traditional Power Optimizers are 99% efficient
Myths 6-10 
  1. Traditional Power Optimizers help me design longer-strings… and that’s a good thing
  2. Traditional Power Optimizers are inherently safer
  3. Traditional Power Optimizers reduce my O&M costs
  4. By standardizing on Power Optimizers I realize cost savings in my installation business
  5. Traditional Power Optimizers are good for the environment

A Superior Way to Optimize PV Systems: ShadeFix

SMA ShadeFix optimization has been proven to produce more energy than traditional optimizers. And if that wasn’t enough, superior technology and a reduced component count reduce lifetime service needs and can cut truck rolls in half.

Check out the new resources below to learn a more effective way to optimize PV systems.

    Hello,

    The link to the White Paper referenced in this “Blog” is not active and I would like to read this new university research. Can you please E-Mail it to me or make the link active.

    Many thanks

    Please tell us who, what, where, when, and how to get a NEC 2020 compliant RSD device that works with the SMA inverters. Specifically the “receiver” or junction box device to put at the array. We can’t seem to find any readily available options and hence still feel beholden to either SolarEdge or Enphase until the NEC code changes or another very easy to use product is readily available. Does SMA make them? Thanks….

      Derek, please see the list of SMA approved SunSpec compatible receivers here. This document lists the options for use with the US-41 line of Sunny Boy and CORE1 inverters from SMA, which provide full 2020 NEC 690.12 compliance. The JMS-F unit has an SMA part number and can be sourced from out Authorized Distributor partners shown on this page. More information about the APSmart devices can be found at https://apsmartglobal.com. If you have any further questions about availability, please contact InsideSales@SMA-America.com .
