I have neighbour who called me out on an Error 24 failure in an Easysolar 48/5000. She saw a rat run out of the top of the inverter when inspecting the failure. She bought the inverter online, not from me. On inspection, I found rat shit on top of the fan guards and inside the inverter. The Easysolar has larger side windows and much deeper well above the fans than the Multi 5000; I guess for the greater heat from the on-board MPPT controller. I think this is a design issue and the units need a grill or bars to prevent rodents entering. Too inviting by far with the warmth.
Hopefully it is a warranty service. I will be fitting a grill that does not impede air flow, but does stop rodents when re-installing. This must be an issue world wide in remote areas with sub-optimal housing
