Grid Voltage Rise Is Getting Worse. That''s A Problem For Solar Owners

The inverter has to be running at a higher voltage than the grid, so it can push power out (current flows from a point of higher voltage towards a point of lower voltage, never the other way around). It is some years now since the Australian standard voltage was reduced from 240v to 230v, with tolerance of between 216v and 253v. It is

Solar and high grid voltage

To help reduce grid voltages, all grid-connected inverters must now manage generation based on voltage. Here, an inverter shuts down eight times between 12.30 pm and 3.30 pm due to high voltages—note where power (the green line) falls to zero. Most solar inverters will also state their output voltage, which will be slightly higher than
