And also, can I connect the 18watt solar panel to a 800 watt power inverter?
I wanna use a car battery to charge home stuffs. I wanna connect the Inverter, the batteries and the solar panel. I just wanna know in a sunny day will it charge the whole battery? I just want the inverter to convert the power from the battery.

The car batteries will charge fine but slow, if the panels output is over the 12.5v that car batteries usually sit at. Also, the panels voltage output may get loaded down by the car batteries and not get charged. Cars charging systems usually put out 14.1 to 14.4v to keep the battery charged. The 800 watt power inverter may be basically worthless with only 18w going into it.
why dont you just let your car charge the batteries???
In short you need to read ratings and ask manufactures. There are lots of ways to figure power using current, voltage and resistance. The voltage has to be around 14 to 15 volts to charge a 12 volt battery and if you only have, say, less than one amp available, it could take days/weeks/more to charge the batteries. On the surface without knowing details, it doesn’t sound feasible and if it is, functionality should be considered, if the battery will be discharged in four hours and it takes two days to charge it, is that really something you want. You need to seriously investigate the system you are planning to build/use.
