Overvoltage

Solar inverter overvoltage disconnection

The Australian Standard for Solar Inverters AS4777. 1 mandates that an inverter must disconnect from the grid if: So if your inverter trips on an 'over voltage' error, the voltage where the grid connects in to your inverter has breached one or both of these. . Inverters are designed to protect themselves from grid overvoltage. When the voltage exceeds a certain threshold, the inverter will shut down to prevent damage. •How can I prevent inverter shutdown due to overvoltage? To prevent shutdown, ensure your system is properly configured and consider. . Regulations require solar systems to shut off if the average grid voltage over any 10 minute period exceed 255V or right away at 260V. I'm pretty sure its getting over voltage.
