hi Everyone, and thanks for the support. I took it apart and it is producing good sine wave up to the AC board but there is a black relay that is failing to close and it turns out that there is a light on the control board showing it is not even trying to close this relay, so that is why we are not seeing output at the terminals. I propose to fit a new control board and hope that works.
This will be the second time I have been inside this inverter (since 2006) and maybe the fourth or fifth time I have replaced a board in a FX. They are easy to work on, but my experience has been they do seem to need it. cheers Hugh Scoraig Scotland > On 9 Mar 2020, at 18:20, Ray <r...@solarray.com> wrote: > > We had one last year with a bad relay, the customer had been charging a Tesla > EV through it (pass through from the grid) and smoked the relay.
