color:#1F497D'>I can’t find the power curve right off, but the DR like
any inverter is dominated by its tare loss at light load, which is about 8W in
this case, so running a 10W load will not be very efficient on a percentage
basis! The DR hits peak efficiency around 300W output.<o:p></o:p></span></p>

<p class=MsoNormal>I need to show a customer that it is not 94% effecient with
a 10 watt ac led pluged into it alone. <o:p></o:p></p>

<div>
<p class=MsoNormal>I am betting that it needs 500 watts to get into the 75 or
80% range. <o:p></o:p></p>
