Hi Y'all i have a question after updating my firmware i reset all parameters but first charge cycle it would not start charging no matter what I did it would not charge. battery at 50.3v parameter 19 = Bulk at 55.2v and parameter 20 = float at 52.8v parameter 21 =low DC cutoff at 48.0v parameters are for a Growatt SPF 6000T DVM and so was the bin I obtained from watts 24. So, I set Float at 55.2v it started to charge I then set Bulk at 52.8v no change it was still charging. I am puzzled! Let me Make sure I have this right Please. Charge cycle should go like this. start of charge cycle constant current till bulk voltage reached then constant voltage held at this voltage till set time for absorption has been reached and constant voltage turns down to float set voltage and hold there till needed.
