I am building a small (2kW) off-grid system with a Outback FLEXPower One FP1-4 w/ GVFX3648 inverter and ET Solar panels. I am wondering whether I would be better off wiring this system as a 24V or as a 48V. What are the factors that I should consider and/or the pro's and con's for each option? Thanks.

You will need to wire in 48Volts, because the inverter GVFX3648 ('48') work only with 48V battery banks.
If you want to use a 24V battery bank, you can use another Flexpower.
The main difference between a 24V and 48V on flexpower is the maximum allowable PV power. The PV input can support the following PV configuration. 4000 Watts on 48 Vdc system, 2000 Watts on 24 Vdc system.
