Hello Everyone,
I have a Growatt 5000 inverter that has been working normally for almost 2 months. Due to the cold weather (around 10 degrees Celsius) I put bulk charging at 58.4 and float at 56. When it is charging on Solar and the batteries are full at floating charge, the inverter can not hold them at float and they will drop to 53 or 54 before the inverter kicks in and start the bulk charge going to 60v and showing overcharge alarm before going down to Float, and then this will repeat till it is on battery power. I have attached a video (zip) and a photo of this pattern. Thank you!
