Are grid-connected inverters approved in Australia?Grid-connected inverters for use in Australia must comply with the prescribed Australian Standards. The Clean Energy Council (CEC) provides a list of these approved inverters. The CEC list is regularly updated and can be found on the CEC website: 3. Section 7.8.3 - Power Rate Limit.
How do grid-connected inverters reduce grid voltages?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. But the 6.3 kW system (5kW inverter) still generated over 30 kWh for this day in late November 2018.
Can a solar inverter export power to the grid?Your system, likely along with lots of other systems in the local area, will be exporting excess solar generation the grid. For your inverter to export electricity to the grid, the voltage at your inverter must be slightly higher than the voltage at the grid to “push” the excess power to the grid.
Can inverters overcome high grid voltage?After this change, inverters were unable to overcome high grid voltage and just shut off instead. This raises considerable issues as energy distributors were already supplying electricity at voltages close to the high end of the Australian standard, some even slightly above 253V!.
What is the grid voltage for a 60038 inverter?The grid voltage Australian standard AS 60038 is 230V +10% -6%, which is a range of 216V to 253V. The Australian standard for your inverter instructs that it must disconnect from the grid if voltage exceeds 255V for 10 minutes or exceeds 260V for any amount of time.
