Check out Tigo Energy's Module Maximizer, a similar product. They claim
that the decreased inverter cost of leaving the MPPT hardware out of the
inverter makes up for the cost of the individual module MPPT units. They
are working with Kaco to provide this special inverter.<br><br>
They also have the advantage of individual data collection so you know
which module is doing what.<br><br>
Out of all I saw at Intersol, these products impressed me the
most.<br><br>
Of course, both of these products may be too young to count on.<br><br>

No to all those things, but... I'm told they are about $200 a pop. Say
they increased output by a total of 5%. Seems unlikely, but say they did.
Speaking in retail, $200 represents what these days... 40 watts or so
including racking, give or take? Say you are using a 200W module. 5% =
10W. Hmmmmm. I can envision some tight spots where that might pencil, but
not many.<br>

Does anyone have any experience with these units?<br>
<br>
Do they work with off grid lower voltages?<br>
<br>
Do they work with all controllers?<br>
<br>
Do they affect MPPT function positively or negatively?<br>
<br>
Do they work well with Grid tie?<br>
<br>
How would you gauge the increased performance?<br>
