<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">This approved list was created to ensure ALL inverter functions perform as expected when SunSpec signalling is used for rapid shutdown. SunSpec certification for rapid shutdown
only covers the rapid shutdown functionality. As new rapid shutdown receivers are certified by SunSpec, SMA goes through our approval testing. So the above document is updated regularly \u2013 please check SMA-America.com for the most up-to-date version rather
than keeping the above link.<o:p></o:p></p>

<p class="MsoNormal" style="mso-margin-top-alt:auto;mso-margin-bottom-alt:auto">The TS4-A-O unit from Tigo does not use SunSpec for rapid shutdown compliance. That device (also requiring an external CCA separately wired to TAP unit(s) near array to provide
rapid shutdown compliance) ARE approved for use with both the Sunny Boy US-41 and CORE1 US-41 lines from SMA. This is the ONLY current unit from Tigo that is approved for use with current SMA inverters.<o:p></o:p></p>
