Hi all.
I have a 400ah 18650 48v battery. Using 250ah of them from 3.5v-4.0v. Charging to 55.6v and then the 0.4v is applied for excess solar to grid = 56v/14cells, 4.0v cell.
I have multiplus 2 48/5000, mppt 250/100, cerbo gx, 6.2kwp array.
This might be a simple question, but I have been wondering this for some time now. How come the victron gear wont charge the full potential to my batteries? Right now im exporting 1500w to grid, instead of filling up my battery as fast as possible?
Could be bad weather later in the day, which means I'm potentially missing out on some kwh's of storage for the evening/night.
Is this due to the 0.4v offset that is applied later on? I know it's not my bms (batrium) there is literally no reason for those 1500w beeing exported to grid right now :-)
Have a great day
