Proven recommend a 10sec T-start! I think that my inverter has a built in feature that is separate from the T-start figure that determines that there is no generation for the 3 mins you mention.

For example I have recently turned the electricity off in the house and the turbine went in “Disturb” mode. Seeing that the wind was really getting up I turned the electricity back on to stop the turbine over voltaging the inverter. I had a scary three minutes as I saw the voltage dial go all the way up waiting for the turbine to kick back in. At the moment my T-start is 30s and I want to take it down to 10secs, once I have confirmed that the disturb mode ensure a 3 mins start up after a problem

It may be that my inverter has different firm ware, as it is specifically designed for a turbine.

How do you get into the inverter settings using Sunny Data Control?
