HI Jim, The CC is sure suspect. You didn’t mention what the battery voltage is. Those CC have a hard PV watt input limit.
You can try and set it back to factory default and then reprogram, sometimes that works. I don’t use the FM-60, but always the FM-80 because of the fan replacement. the 80 takes 3 minutes, the 60 takes 2 hours. jay > On Apr 23, 2024, at 6:00 AM, Jim Gowdy via RE-wrenches > <re-wrenches@lists.re-wrenches.org> wrote: > > I'm troubleshooting the solar aspect of a small offgrid 120v outback system > and need some opinions.
