Hello i tryed to instal smart meter and now inverter show meter fault Pax=0,Pex=0.How to reset or fix this problem?
Depends on which type of meter you have fitted but essentially it is the same answer - it is likely reporting a damaged cable between the inverter and the meter (or CT clamp) - the cables are small multicore and very easy to break their connection.
Check you haven’t disturbed the meter or CT clamp cabling, that it hasn’t been cut or damaged.
