Generator Charging Multiplus with Lithium

Hello All

We have a Multiplus 48/3000/35 whereby we have recently changed from AGM Battery to Lithium. We charge most of the time via MPPT 150/70 regulator and it is great - but sometimes in the winter we need to run the generator input to the Multiplus to top up the batteries. Now that we have connected the Lithium and when we run on Generator it seems to be slow charging and never goes to absorption or bulk charging of any type. It basically just charges around float voltage 52V the whole time. I can post the settings I am using if it helps or if someone knows which setting will affect this then that is helpful? - any suggestions welcome on how to ensure better charging when using generator are very welcome

Did you change all settings off the Multi, to the right battery type and capacity?
