I have 350w of solar on my sailboat with the 100/20 mppt charge controller and the bmv-712 connected to 400ah of lithium batteries. The batteries consist of 16 individual 3.2v cells grouped up into 4 12v supercells and then connected in parallel.
My issue is that my bmv-712 will read 100% and be at 13.5 with the solar charger still in bulk pushing 260w all day long without ever leaving bulk or changing the voltage of the batteries from 13.5v. Manufacturer of the batteries say it should go up to 14.6v and then drop down
