My Deye inverter fails to reconnect to the grid after power is restored but it connects when I switch the inverter off and on again. Eskom voltage is at 250v and the only change is a software update that I got last week. Please see attached pic for grid settings

How long a period are we talking about?

The inverters are not meant to reconnect immediately the power comes back. They are supposed to wait a randomised time and then reconnect. This is deliberate and all good brands (IE inverter is on the approved inverter list) do it so as to not contribute to surge on restoration.

Then there's the question of WHEN they deem grid to be available. My Goodwe watches frequency and voltage and when they are within tolerance then it reconnects. I can adjust the tolerance on the voltage, but then I run the risk of my inverter not letting go when voltage drops low and causing damage to devices on the backed up circuits.

How possible is it that turning on and off is just taking the time that would have been taken by the above anyway?

Add wording about changing voltage tolerance.

I learned this lesson with my heat pump. Sometimes in cold weather it gives a beep on start up. And I am instantly awake and thinking OMG there's an ERROR and I go running over to the DB to turn the geyser circuit breaker off and then back on again which is enough down time to screw with the pump's own clock which I then have to reset and then the thing starts working again.

The reality is that the beep just indicates some sort of unhappiness that prevents it starting now, but if I give it a little time (about as much time as it takes me to run to the DB and etc...) it will clear that error condition and start running as usual.

So now I treat that beep as "it's your turn to get up and make coffee".
