[RE-wrenches] SMA 1800u not generating power

[Sky Sims]

This is a known issue. 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. 
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.
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.
