No where I could find do they same if it is modified sine wave or pure sine wave, which often means it is modified sine wave and would likely not be a great choice for sensitive electronics.
At 1000 watts and two batteries running a 5.8cf compressor frig, the batteries are probably not going to be near full much of the time, so using the inverter at high load for any length of time would not be good for life even if the batteries would supply the 100 amps of so required to get to 1000 watts of output. IMO, you will probably find that the 190 watts of solar, in average sun will probably be almost all used by the frig most days, depending on how much the frig uses. Frig power use can be very highly variable between vans and quality of the installation and venting, we have seen on here. Depending on how much use you have beyond the frig, you will likely need to be getting a good charge every couple of days unless you got really perfect high sun conditions.
1000 watts will not run the AC or convection oven, especially on only 200ah, but in general also. No hair dryer unless very small or electric heater. Most other stuff will run on 1000 watts, but if modified sine wave you likely will find it not very good for some electronics and also electric motors don't like it in general.
