Contacted my supplier, they have managed to set one of my inverter to 180sec. They said it was a back end task by growatt engineers. I cannot rely on them for all the interventions.Hi Sorry for that. I'm actually working on a MIN2500, MIN3000 and MOD 500TL3-X in parallel. All of them are having reconnection time of 65 secs. Need to change them to 180secs. The tools should be the same, but I want to know where exactly to change this parameter.
