Updating an older system

My neighbour has asked me to help revise his older system, take out a DR and SW and put in a Outback FLEXware with two VFX2812's. Now the older system is run through an APT Powercenter with each inverter being on its own T-400 amp fuse....no big breakers in the system now and he does not what to let go of the APT Powercenter just yet. Would I be correct in thinking that I can just run from the T-400 fues to the 250amp breakers in the FLEXware DC, giving added protection to the inverters by also incorporating the fuse's in the system?

    With the update, why not try to go to a higher voltage with the array and batt bank.

    He would be able to run a single larger inverter like a XW or magnum, save some money and get a better CC!

    I bet there will be some picked up eff from less current and voltage closer to output...
