Post in thread: What triggers Growatt 3000 to exit float and resume bulk charging (via solar)
This thread may be covering or confusing 2 separate issues. With 1 set to "SBU" and 19 = 20, my Growatt will bulk up to about 0.5V below 19/20, then kick into float mode. It actually never reaches 19/20 but stays about 0.5V below. I dunno why it stays 0.5V below the setpoint but since that...- Reaction score: 2
