Hi All, I have a 13.5 kw AIO + Gateway with 2 solar arrays; 4kw with a Fronius inverter and a 6kw with a Fox inverter. Last Saturday we had a power outage which lasted about a minute, the whole property lost power no mcbs/breakers were tripped and the system rebooted. However, I now have a problem where the AIO and Gateway will only charge to 90%, then the frequency (hz) goes from 50hz to 54hz and shuts down both solar inverters but does not trip any mcbs/breakers.
I have done a complete shut down and restart of the system but the problem keeps repeating.
I have noticed that the “Grid Meter” inside the Gateway sometimes flashes continuously so I have shut everything down and restart again.
Any help or advice will be greatly appreciate. Thanks Alan
Cannot answer your question, but with the AIO you shouldn’t have spotted the ‘outage’ as it switches over to off-grid in milliseconds. Make sure the ECO switch in settings is on.
We have had grid outage, flicker of lights only indicator, TV never goes off etc.
Have settings changed for max charge?. If battery is full and solar cannot export to grid then the system will shut down. Worth checking out. Mole.
Thank you for your reply. I think the problem is that the Inverter is sending false messages to the Gateway .Alan
So I have the same AIO, but two off Growatt solar inverters. In the event of a power cut I was losing everything and with some digging the frequency change kills the inverters until the grid returns. I spoke with Growatt and they provided a software update that allows the solar and inverters to continue to operate during a power cut. I was also told that if the battery reached 90% charge during the power cut the inverters would be switched off as the solar power would have nowhere else to go. Might be worth speaking with your inverter support team as they may be a similar software fix to mine.
