8kW Sunsynk Inverter in Parallel on same phase with export on
I have one site where there is 3 inverters connected in parallel and when PV is present the output AC voltage rises if solar export is selected and the output voltage rises as high as 260V with the solar input when it increases in power. This looks like a software problem – the more inverters in parallel the higher the output voltage. (This also happens when 5kW inverters are coupled in parallel on the same phase)

Question - how far from the grid service connection is the inverter and what size cable do you have between the inverter and the service connection?
