<p class="MsoNormal"><span style="color:#1F497D">Just a word of caution to those not having experience with SMA TL inverters - the larger units (7-11 kW) have an extremely narrow input DC voltage window. Depending on your module voltage and string design,
all you need is a module or two to be shaded to fall out of the MPPT input voltage range. The smaller units (3-5 kW) with the Secure Power Supply don't have this problem. We no longer use these larger SMA TL inverters unless we can do maximum string length
(e.g. strings of 8 for SunPower 96-cell) and there is zero shade at the site.<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">I believe SMA is in the process of adding larger units to the line that has the Secure Power Supply. They added the 6 kW unit earlier this year, and just announced the 7 kW unit with Secure Power Supply.<o:p></o:p></span></p>
