Hi
My solar system was upset when I had a heat pump installed and they fiddled about with the electrics. It says Code-169.
Is this something I can reset myself?
Thanks.

That's a strange error (sample fault) - I think the first step would be to do a full restart on your inverter.

Basically you have to open the PV isolator, open the AC isolator, power off the batteries - wait 30 seconds and then reverse the process. - - this video guide will help to do that. viewtopic.php?t=5

If that doesn't work, I would suggest emailing Fox service service.uk@fox-ess.com with your inverter serial number and ask them to review it (they can do that remotely)
