Interesting that you quote 256v max. We specify all our equipment to 264 which irritates the suppliers but we are buying a couple of million a year and don't want the hassle and risk of burnouts.  People installing PV part way down a run doesn't help the stabilisation and traditional expected line drop.

Well nominally the UK is now 230 plus 10% max = 253. The 256 is the highest my UPS recorded (but only samples every 20 mins)

The 'RECS' or electricity supply authorities are legally bound not to exceed the upper limit.
