Victron MPPT Controllers

Hi again, I have a quandry I am trying to find a work around. I realize my controller cannot completely charge my batteries on the Sun due to the way the charge controller limits the power to the batteries in Absorb then Float. So I am running the genny for an hour in the morning to bulk up the battery to about 80% or so. Then the controller runs in bulk for an hour or two and then absorb for a short period of time due to the battery voltage being a bit higher when it wakes up during the genny charging. So it goes into Float way too soon.
I am normally running the Inverter all day and night and quite often the Controller in Float produces less than what the inverter is using so I am negitivly charging about an amp or so. How do I fool the controller to put out more amperage to at least be putting in the 4-5 amps into the battery it thinks its putting in but is not due to load on the batteries? Ideas? -Bill
