I've come across a bunch of their inverters that have had this problem. In addition to seeing this issue on their 1800's I've seen it happen on their 2500's as well. Shows a solid green light but isn't putting out power. </div><div>The first time I came across this issue they had a refurbishment program, where they would rebuild the inverter and send it back with a one year warranty for under $400. The refurbishment program was a great program that I hope they bring back someday.</div><div>The last few times I contacted SMA about one of these defective inverters, they said the product was not under warranty and they no longer supported it. Only option they gave was to buy a new unit. <br><br>Sky Sims</div><div>Ecological Systems<br><br></div><div><br>On Jul 24, 2015, at 5:49 AM, Jason Szumlanski <<a href="mailto:jason@floridasolardesigngroup.com">jason@floridasolardesigngroup.com</a>> wrote:<br><br></div><blockquote type="cite"><div><p dir="ltr">I am looking at a 1800u from 2004 that has a green light and in mpp mode, but Pac is zero.
