If it's only a minor inconvenience, I would say it may be best to stay as you are. In order to upgrade the potencia, it would be necessary to get an (authorised by Iberdrola) electrician to issue a 'boletin'. This is a document certifying that your electrical installation is up to current standards as dictated by the government regulations. Depending upon the age of your house, and the quality of the electrics, you might have to get a considerable amount of work done to upgrade the wiring, sockets, etc, before this document can be issued.
Might be best to wait until the tripping really gets on your nerves!
Our potencia is 5.75 kw and it has never tripped-out, summer or winter. We live here full time, not just for holidays.
