Hi - new installation on our boat, MultiPlus system with 4x 200AH Victron LiFePO4 batteries. When connected to main power to charge (ain charge only mode) Mains and Buls LED illuminate, absorption and float flash, system kicks in, fan rush etc. After about 1/2 hr bulk LED goes off, absorption and float flash, fan off, mains stays on. However, the charge read out for the batteries shows no increase in charge. Have charged for a total of 3 hrs over the last 2 days (only 3 small LED lights and a floor water pump connected to system) and charge just continues to slowly drop as if it is not being charged at all... currently at 40%. Thanks.
