High voltage trips, local grid instability


Hi My ( second) inverter (first failed after two years ) ( Sungrow sg2k5tl) has tripped twice recently with VAc high . It recorded 252.4 then 253.8v every few seconds. I've reported it to WPD who installed a voltage recorder for a week then it tripped again. I recalled wpd who examined my meter and found 246v , reporting no problem, grumbling most of their call ours are the fault of Solar PV. I altered my inverters setting to 256v high and so far do good. I received a letter this morning, confirming they are at fault and the supply will be upgraded soon. Anyone else recording high voltage? I know Southwell exchange is notorious for instability ( Hockerton turbine has been hit by numerous surges) for householders even the lights are noticeable!). Hopefully their recent expiremeant will be rolled out soon. http://www.solarpowerportal.co.uk/news/western_power_distribution_capacity_used_by_solar_pv_20_lower_than_assumed Regards,

Yes we intially experianced high voltage interuptions. However, following a number of complaints to the network operator the sub station has been upgraded. Our village has a number of PV installations so they had little chance of saying all the installations were faulty.
