The website has the details of the complaint, which has been filed with the Public Utilities Commission, but in essence:
We decided to purchase a photovoltaic system and feed energy back into the system via GreenPower of NC. From the start their main objects seemed to be to stall, misinform and discourage. It became evident that the people we were dealing with had little idea about photovoltaic or interconnection processes. Either that or they were being intentionally malicious.
The final straw came after line surges (which "Snuffy" Smith, head of ... suggested as the probably cause of the problem) blew up our second inverter within a year. He suggests it is not up to Duke Energy to police their line to keep surges from destroying our equipment, even though we have to provide proof of insurance to make sure we don't damage theirs.
We can't replace $2000 inverters twice a year. Hell, we can't afford to replace the inverter at all.
