Solar voltage for a 48 volt bank?

[KTP]

For 600 watts of solar comprised of three 200 watt CIGS panels, 48 bypass diodes, 30V open circuit, do you think wiring them in series would give enough voltage to allow a Victron MPPT buck charger to keep some power flowing into a 48 volt LiFePO4 bank even during partial shading or cloudy conditions? On paper that is 90 volts open circuit, but I imagine in real world conditions the open circuit voltage is somewhat lower. If it drops below about 56 volts, the Victron isn't going to be able to do anything at all.

Didn't really want to go parallel and don't have room for another panel (even 600 watts on a 17 foot boat is challenging to say the least).

The Max. Power Voltage Vmp (V) is 24 volts so 72 volts in series. It should work.
Parallel wont work at all.
