Someone contacted me off list and said this company does out of warranty SMA repairs:
http://www.shop.solarcowboyzoutlet.com/Inverter-Repair-Service-Inverter-Repair-Service.htm Looks like there is a risk in how big the repair is, but apparently they are willing to talk about the diagnostics before you send it in, and fix minor problems for a flat rate. One bad part about these small systems is that labor to repair or replace failed units can easily turn into a cost equivalent to years of energy production, not to mention the hardware cost itself... I've only sold a few "tiny" systems over the years, and never really considered this. It makes much more financial sense for an owner to replace a failed 5kW inverter when the labor is basically the same as a 2kW.
