Several comments. First, sounds like a 50 amp box with two bus bars However I seem to recall a Progressive Dynamics box that was set up for inverter.
In MY Progressive box the breakers are lined up like this
Main-1 Main-2 L-1 L-2 L-1 L-2 L-1 L-2
L can be "Leg" or Load" all the 1's are the same leg, all the 2's are the other leg.
I seem to recall they once made a box designed for use with inverters.
This one was layed out like this. Main Load, Load, Load Load Inverter Inverter Inverter
If you do not have an inverter simply jumper the two buses, or put in a 30 amp breaker in one of the slots and move selected breakers to the "Inverter" bar. (Feed the inverter bar off the 30 amp brance breaker)
In my 50 amp house when they added the inverter... They put in a whole new breaker box.
