I had an inverter failure, during the oppressive summer and tried to get an electrician to check it for me. 20 tries and not one response, not even to say we're busy. I bought a new inverter and cable and installed, but not powered up, then tried to get an electrician. This time I got one response out of another 20, only to tell me that they do not sign off other people's work, even though most electrical jobs are on other people's work! So, what do I do now, with the system sitting there and no one interested, not even from a safety viewpoint? Any suggestions would be helpful, but not the abusive type.
