Morning, I installed a 5kv meccer inverter, I found out that my incoming voltage is 253v, so my inverter every hour trips on over voltage to that, is there a setting that I can adjust to overcome this problem, as we do not get any joy out of the municipality to fix the incoming voltage, regards Carl

Not a answer but another question or 2: where do you measure or get the 253v value? How sure are you that this value is correct? If your inverter measure the grid V too high, the problem might lie with your inverter's calculation. If the grid is really so high the Municipality can change a tap on the transformer.

Install smaller or longer wires and run bigger loads. Volt drop is typically unwanted but in your case it may help.
