Portable PV System

For my university project this year my task is to implement solar technology onto a pedal bus, also known as beer bus or party bike in some places. However i need some help in determining the correct size of different circuit elements required. So far the battery pack is a 3 kWh, 48v lithium ion battery pack (was sponsored). There are 3 PV banks available to me to use with this project Bank A-369.8 W, Bank B- 355.8, Bank C- 334.3W. The Ioc= 6.3 approx. for the banks.

I need to select an MPPT as well as other circuit elements that would be required in such a set up. 

I'm hoping I could get some help as I am new and kinda lost at the moment in the design of PV systems

    Is there even a 48v charge controller out there for lithium?

    Solar hybrid gasoline generator, 7kw gas, 180 watts of solar, Morningstar 15 amp MPPT, group 31 AGM, 900 watt kisae inverter.

    Solar roof top GMC suburban, a normal 3/4 ton suburban with 180 watts of panels on the roof and 10 amp genasun MPPT, 2000w samlex pure sine wave inverter, 12v gast and ARB air compressors.

    Morningstar and Midnight both make high end charge controllers that can easily programmed to whatever you want.
    You need to program your Inverter LVD for the cut-off of your bank
