SolarMan Silver Lakes

I am a professional installer of solar systems. I currently have a client that has a Schubart 6.8Kva Inverter installed that has bombed out twice and was repaired by us. Now I am looking for the installation manual for this inverter that is not available anywhere on the internet, the system has bombed out again, and on the SolarMan website, the contact numbers are no use, as there is no answer on either of the numbers provided. (If you work in this industry you should be available to your clients at all times 24/7 365days a year) So it seems that Solar Man is only in this for the sales, as there is no after hours of after market service for their clients. We as a professional solar company are available to our clients at all times 27/7 365 days a year. So it seems that SolarMan as a supplier are not on the same page. I have tried various times to contact Solar Man to get my hands on the manual of the Schubart inverter that they are marketing without any response, in order to help my client resolve this issue as they are now without any electricity. Why is it that we can find 90% of inverters imported into SA manuals on the internet, but not this one or any of Solar Man's manuals are listed on their website. Please respond immediately
