This is something that has only recently started happening, randomly my power kept tripping, so I did some tests and flipped the RCD back on, with each of the individual breakers switched off, but it would still trip the RCD, even with only one breaker. Then one day I was in the garage (where this is all setup and my inverter made a clicking noise and at the exact moment, the RCD tripped.
So I thought maybe there is a firmware issue, so did the firmware update and all has been good for about 2 weeks. Now it has started happening again. I restarted the inverter and it has not happened for a day or so.
Why would this just randomly start happening after operating well for a period of time?
One thing that I should mention, when I did the last 2 firmware updates, it did not do a calibration.
And I don’t seem to be able to find a ‘calibration button on the iPhone app or on the website app!
Any advice would be much appreciated.
