The USE/STORE switch is just a remote operator for the battery disconnect relay. Do you hear a distinct "CLUNK" when you operate the switch in either direction? If not, the latching relay may not be operating. This can be caused by the tripped 50 amp DC breaker near your house batteries as mentioned above (looks like this but the flag/button may be different colors):
Or:
There is a small (5 amp) inline fuse for the control of the latching relay right at the latching relay - that may be blown which prevents the switch from operating the latching relay.
