Adding Inverter for dry camping
I would like to add an additional battery (have one group 27 now), possibly a solar charging system and an inverter. I hate that the 120V outlets don't work on battery power. Seems crazy you can't...

Hi,
The only effects on the 12 volt systems is that running the inverter acts as an added parasitic load. Of course, running 120 volt devices also tend to draw down the battery bank quickly, because of the Peukert effect.
For example a 120 volt toaster may draw about 120 amps while it is on. That is expecting a lot from a tiny bank, so large draw items should be limited in the time frame they are used.
It is needful to have some way to replace the energy used in operating the electrical items in the RV. I prefer solar for that.
Mex makes a great point. 12 volt adapters are generally between 15 to 20% more efficient than powering the same device on an inverter.

Does that affect any of the 12V systems? Like the water pump?
