Powering an Oxygen Concentrator

Hey everyone:) I have a Caire Companion Eco Oxygen concentrator that I use mostly at night when I am sleeping. It has a 350 watt maximum rating. Although I have a 4000 watt generator onboard I don't want to run it for prolonged periods of time so I am looking for some input on how much solar power would be needed to run the concentrator and perhaps even a toaster or some other small low wattage appliances. But am mostly curious about the concentrator. There is a 100 watt solar panel mounted on top of my Class C but I am sure that it won't be enough to do what I want it to do. So any help would be greatly appreciated.

!. How many additional panels will I need?
2. What wattage should they be?
3. What size of an inverter should I use?
4. What would be the best controller to use with the system?

    On the other qx,
    Inverter? you would want at least one rated for 400 watts continuous, 600 watts would be better. And it should be a pure sine wave inverter.
    Not recommending any of these, just examples, inverters

    On the controller, you may find it easiest to get a kit from a company such as Renogy which would have the controller included.
    If you are going to have a total of 400 watts get at least a 40 amp controller to allow an extra panel or two in the future if needed, without having to change the controller.
    Examples, solar kits

    If your insurance is paying for you concentrator, ask your provider about switching to a portable battery operated model like one of the Inogen One models. The G3 for example, only draws 10 amps using the 12-volt power cord and with their rechargeable double battery runs 10 hours on a charge.
