What you need for the solar panels, even before the inverter, is a solar controller. These may differ from unit to unit, depending on the output of the panels. Do your research, get the details on the panels. A marine type (trickle charge) battery is also needed. Again, it depends on the output of the solar controller. Only after that can you use an inverter (I assume you mean DC to 120V AC). Knowing the Ah output of the panels would be helpful too.
Don't start hooking up untill you know your putting a round plug into a round hole.
