Solar generators

They are packeges consisting of sall solar modules connected via a charge controller to a battery. Both the solar modules and battery are DC devices. The battery in turn runs and inverter which produces ac output from the dc battery input. So, not a generator at all.

The problem with using one of these packages in lieu of an actual generator is that they produce very limited energy output. Energy is power x time so one might have a 1500 watt power capacity but can only produce this for a few minutes before the battery is discharged. in comparison a generator will run as long as you have fuel to power it.

The other issue is that it would be terribly inefficient as most of the load devices in the trailer are 12Vdc and are charged by the onboard converter.So you would be taking DC output from your solar modules, using it to charge a battery, then converting that to ac to feed to the trailer, then converting it back to DC to charge the trailer battery, then finally to the end load device in the trailer.   You would lose at least half the energy you had available if you just charge the trailer battery directly from the solar modules.

You can get portable solar modules and a charge controller which can directly charge the trailer battery without having to be permanently mounted, so they can be used for other things. That is they way most folks do it and a much more efficient solution than one of those package systems.

Just for clarification, when I hear the term "solar generator" I think of course, of a generator. In reality, are these basically self charging batteries?  Just a normal 12 volt battery, that also has maybe a small inverter or converter, that allows very small electric appliances to run, but recharges itself with a solar suitcase or panel? So it's not at all a generator in the sense of the word. I'm not looking for the " well technically it could be called a generator because....."
