When you guys are up in the morning, get out your multi-meter and check the house-batteries while off shore-power. Check voltage first at the battery-terminals and write it down (12.7 volt or less. More is surface charge). Then have him start the engine and get the voltage reading again. The voltage should rise to 14.4 to 15.0 volts if alternator is charging the house-batteries. If not, bad solenoid or connections. It wouldn't hurt to do same to starting-battery.
If he can start the generator, then take reading of voltage at the house-batteries to see he is getting 13.6 to 14.5 volts. If not check the breaker and fuse.
This should eliminate the obvious electrical issues before mechanical issues.
