Welcome to JOF!!!
To give you a little better answer we could use a little more information.
- What mfr, size and Ah rating is the battery(s)? (Interstate, Size 24/27, 84Ah)
- How long do you plan on dry-camping? Week-end? Week....
- All LED lights in the TT?
- Cold weather camping? (need heating system?)
- Watch much Tv at night?
The numbers add up..
In short....
AC is out, with standard batteries, more than likely the microwave is also out other than heating up a cup of coffee at high-noon with no cloud cover. You will get a few nights of cold weather camping.... but the 160 watt SOLAR panel will not be able to recoup all your Ah usage and in a few days you will not have enough power to run your heating system over night (in cold temps)
Add shade or cloudy/hazy days and your SOLAR output will be down to maybe 25% of the total.
Check out the JOF "
RVing with SOLAR" social group. You will find a lot of SOLAR and BATTERY information there.
Again welcome to JOF
