I have a 1200 W renogy array.  8 150 w at 12 v. with midnite classic 150 96 v charger and a aims 4000 w pure sine inverter. 
I what add to my panel array. Will a renogy 300 w  at 24 v panel work?  Battery bank is 24 v

    You generally want added panels to be within 10% or so Vmp, so (eg) if your 12v nominal panels are 18Vmp in strings of 2 for ~36v, adding panels with a Vmp around 33-40v should work.  If the new panel is more like 30Vmp, it isn't likely to work well.
    Off-grid.
