Forgot to mention that the 2 x 380 W panels most likely are not going to do the trick for you. Realistically speaking you will get a max of 80 % of Max Wp and that is only in summer. At the moment I have spring here and I can see 40 - 50 % of Max Wp during a few hours of the day. The angle of the sun is just to shallow to give me more output.
The one thing that is saving me is that I have 3.2 Kwp of solar and that ensures I can bring the batteries up to about 90 - 95 % in this period of the year. Have to say that I have heating running, a boiler, induction plate, dish washer, washing machine etc running on a regular basis. If you don't have that it is not going to be a problem, but 760 Wp will have a hard time charging AGM batteries to 100 % outside of the summer season. To be honest, I think you will need more solar.
But it is also a matter of power management. Simple things like: 'don't run heavy equipment in the morning when the solar is recharging the batteries'. Just wait until the batteries are charged and then start using the heavy draw equipment. That could mean preparing food in the afternoon, on solar power, so that you just need to warm it up in the evening. Running a washing machine in the afternoon instead of in the morning. It takes a bit a planning, but you will get the hang of it.
Also, don't forget you can have multiple days of rain and in that case you will need the generator.
