Fatboy Posted January 16 Share Posted January 16 (edited) Hi Can you advise what your current firmware version is. We had loadshedding on Thursday evening and inverter was working well for about 1:50 minutes until I switched on the kettle and immediately the inverter tripped and displayed error message 04 and 20. Since then, the inverter is displaying the error message even after few reboots. Had to change my settings 05 from Li to Use. I suspect the problem might have to do with commutation error maybe resulting in inverters firmware version.
