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?

    Your response is appreciated :) As far as batteries are concerned, would it be best to get like 2 12 volt or would an additional 2 6 volt deep cycles work? I have 2 6 volt golf cart batteries for house power now.

    If the O2 is anywhere close to 350 watts continuous you are really looking at 500+ watts solar and more battery. May still need to run the generator some to do some bulk charging.

    So 4 or more matched 100 watt panels.
    400 watt sine wave is fine for the O2. Need to verify the rating of that toaster etc.
    I like Morningstar controllers. 45 amp should do it.

    Determine the battery power needed. The panel watts necessary are determined total battery amp hours and your location. Solar panels don’t run anything and toasters are not small users. 350 watts is a bunch.
