Purchase a 2000 watt Honda or another brand of choice and make that your charge station. If you sit it in the sun when using it then you could call it a solar generator I guess! Just kiddin, but in all reality, unless you plan on a decent sized solar system then from my understanding your better off with a gen. I have an onboard gen but I also have a Honda that I used from my last RV and use it still just to keep the batteries charged and to run coffee maker and stuff as it gets better mileage than my 5500 Onan!
