I have checked all fuses and circuit breakers. Have new 50 amp fuse beside solenoid. Any other checks I should do before replacing switch and solenoid.

How do you know the batteries are fully charged without putting a voltmeter on them?
Are you relying on the status panel in the RV? Faulty logic there. It requires 12 VDC to operate which you can only get from the converter. The same converter that is connected to the "battery status" sensor which will obviously show full if on SP.
Before the battery voltage gets to the DC load center it goes through a 50 amp DC circuit breaker normally located very close to the batteries.
In case it wasn't clear above, the latching relay (controlled by the USE/STORE switch) gets its control power from the batteries. So if the latching relay is in STORE position, it will not change position unless 12 VDC is available from the batteries through this circuit breaker.
And there are either one or two fuses on/at the latching relay itself that need to be checked to see if they are good. If blown, the latching relay will not respond to the USE/STORE switch.
As I mentioned above, a multimeter would quickly solve this mystery.
