The generator or rather inverter is 2800 Yamaha it only bogs a little when using microwave. I turn everything off when using it. I did use a regular generator for a while it was 3500 it did work hard with the window air conditioner that's why I switched to inverter.

2800 should be more than enough. 

I have a Honda 1000 "inverter" generator (800w continuous) and we used it during Hurricane Irma. It ran a full-size refrigerator/freezer with no problem, though we didn't try to run anything else at the same time. From time to time we'd unplug the fridge and power up the TV and satellite so we could get news on the storm.

Which Yamaha 2800? The specific features of the generator can come in handy later when planning the Solar PV system.

Appears there is only one, the 2800i.

By 2800 does he mean rated, maximum or peak? 
For example: Yamaha EF3000iSE is rated for 2800 Watts, maximum 3000W, peak 3500W. There are some others rated for 2800W.

Sorry its a ef2400I so max is 2400 rated is 2000
I borrowed  Honda 2000 when I first built and it struggled to run the air unit. When I bought the Yamaha I was hoping the extra would do the trick, it did. I would have bought the 3000 but was way to heavy to carry.

EF2400IS is rated for 2000W can do 2400W for up to 20 minutes. It does have a 12V output. It does not have a remote start, but it should be an easy hack to add one. Could be interfaced with the right charge controller to supplement PV production.

If you can power the things you want to power off the EF2400IS without tripping it, that would be conformation that a 2400W inverter is enough.

Start compiling a list of refrigerators and dehumidifiers for consideration.  We can look at the specs and help you make a good choice.

Unless you're going to try to run the AC with the inverter, you won't need anywhere near 2400w. If you ARE going to run the AC with the inverter, your biggest problem will be batteries.

Most small generators have a 12v output BUT:
A. It usually can't be used at the same time as the 120v output.
B. It's usually very limited in its output (8 amps or so).

(Check your owner's manual)

If you want to charge your battery bank with it, best to plug in a battery charger. Been there, done that. My little 1000i can carry a 30 amp charger easily. A 2400 watt generator could handle a lot more.

Or choose a Charge controller/Inverter with a Generator/Utility input.

That would work but I think it would be expensive and overkill for such a small system. 

An inverter-charger with a separate charge controller for the solar would I think be less expensive, and could be more easily configured to the setup, as more choices are available.

Configuring for 24v or 48v would probably be less expensive than 12v, unless you need to have 12v.
