Invertor questions

Do many use inverter while dry camping to avoid noise of generator? If so, would appreciate advise on purchase, size and any problems.

An inverter uses your batteries to produce A/C (outlets).
How are you going to charge your batteries, when they get down to 50%?
Plus for every 1 amp A/C equals 10 amps DC.

My inverter has been on 100% of the time for the past 4 years because of my RR frig. When I get down to 12.2 V I start my genset to recharge my batteries. The last time boon docking 6 days, 1 hour in the morning then about an hour at night then if we have to use the micro or something I start the gen set. Never let the batteries get under 12.1 12.2 volts or you will kill the batteries.

On my EMC and the Magnum controller it tells me where the battery charge is at, you could install a volt meter in a power port to get the same reading, I keep one in all the time so when I open the door I can see what the volts are.

Solar (not a subject I have much knowledge of) will keep the batteries charged while an inverter will enable you to use AC powered systems (TV, PC, residential fridge, recharging phones and such) when shore power is not available rather than running the generator. If your solar array is large enough and you conserve power you can get to the point of never running the generator except the weather prevents efficient solar operation

My dry camping has been very limited. Mostly the first night out leaving after work on an extended trip so 2 budget minded Sam's club GC2 6 VDC batteries and a 2000 watt pure sine wave inverter has served me well to keep a residential fridge cold and a bit of TV watching before bed.

Regarding inverters, pure sine wave will give you more options but at a higher cost. There are some devices that may not like the taste of a modified sine wave. High wattage will also give you more options but costs can increase quickly. Also high wattage inverters will require heavy DC power cables from the batteries also increasing costs and complexity. Over sizing can be expensive while undersizing will limit options. You'll need to look at you wants and needs and size the system to fit.

All depends on what you want to run off the inverter. A 2000 watt inverter will run a microwave or toaster plus any other small AC appliances . If you have 2- 100 amp hr 12 volt batteries , the inverter will run a 1200 watt toaster for 1 hr , discharging the batteries to less than 50%. It will then take close to 1.5 hrs of generator running to fully recharge the batteries.
The inverter is great if you want to toast something , or heat something in the microwave without starting the generator. With all the other loads you will still have to run the generator for a couple of hours each day to keep the batteries charged.
