I have recently updated my MPPT charger to the latest firmware and after doing so the DC-DC charger seems to be causing it to cut out and it runs at 2W despite there being loads of sun. I have to turn off the MPPT and unplug it, then plug it back in again to get the solar to work properly. Any ideas what could be causing this? Everything has been running fine for 6 months+ and has started doing this just this past week. Any ideas?
