I have 300ah sealed lead acid batteries and it's a perfect match with my 500w of solar panels. The issue with them is that you can only use 150ah because otherwise you will damage the batteries. With the 200ah LiFePO4 batteries you can use 90% of the amp hours and the battery life is like 100 years. It's definitely better than what I have.
I ran my all electric van on all 200ah lifepo4 for 4 years. Its normally just enough if you have some solar panels, we had 525w. Unfortunately, a day or two with no sun and no alternator charging would require using the generator on occasion to keep topped up. I just recently upgraded to 460Ah and 700W solar. I hope to leave the generator at home from now on.
