If it is a camper, then you likely have a device onboard that does charge the batteries when plugged into shoreline. It is usually a "converter", which converts 120 household current to 12 volt DC current. The cheapest of ones will put out 13.6 volts DC current, a float charge, to the battery, so when you are using DC appliances there is a lot of converter DC power to run them and the battery does not get discharged. If you need more "amps" than the converter can supply then the battery will deplete, but big amp draws are usually temporary, so the discharge will be short-lived and minimal. Your fridge might be able to run off of DC power, and possible that the converter cannot supply enough juice for that, but it just depends on your power supply, if you are plugged in the fridge should be running on household 120 current and not 12v DC anyway.
The solar is a totally different system unrelated to the converter. Both solar and converter will put electricity into the batteries, think of it as having two glasses of water and both pour water into a bucket of water that has a leak and constantly needs more water.
I do not know, but I suspect that an inverter charger would be like an inverter generator. An inverter generator makes AC current, that is turned to DC current, and the inverter turns the DC current back into AC current. This is done so the generator can run at different rpm's but still put out the same 120 volts of AC household power. Maybe an inverter charger goes through these hoops so it will put out CLEAN power. Many campgrounds have very dirty electricity. Sometimes the electricity is too low, or sometimes there might be surges because the electrical system is wired so poorly and the entire campground is on the same power feed and demanding lots of power for fridges and AC units. The inverter thing could be a way to filter out dirty electricity, anyone want to chime in? This is just my guess to get the conversation moving...
There are DC to DC chargers that use a similar concept also.
