So I am worried the grid voltage exceeds normal voltage tolerances.

I know at my place in sunny QLD AU, we get over 260VAC at times when the sun is shining & the loads are light.

The inverters are supposed to be limited to about this voltage but ours is not. The installer was not interested in resetting it.

The only real casualty I've had was with a fairly large SMPS I got on line awhile ago. One of the series mains filter capacitors let out heaps of smoke & unpleasant odours. Got full refund though.

The voltage ratings of most stuff advertised doesn't really fit the maximums we get here.
