WFCO Converter question RP190

Recently received our Inergy Apex solar generator, and was wondering if there is a way to connect to the campers converter via the 30 amp, without having to charge the camper batteries? Is there a fuse I can pull in the converter? I’d like to be able to power just the outlets in the rpod to save the battery in the Apex generator. We typically camp where there are strict gas generator use rules, so having a silent source of power has been great! The converter on the rpod draws 400watts even when the rpod batteries are full. We still see almost six hours of use with one portable solar panel connected to the Apex. I was told by the dealer that a battery must always be used even when connected to shore power/generator. Thanks in advance for your help.

If the camper batteries really are fully charged, the converter (if switched on) will taper back to around 100 watts or less in standby. But, several 12v items will still pull small amounts of current...so with everything combined, the standby draw can be past 100 watts, but it should not be 400 watts if the battery is fully charged.
