First, hope to meet you at Quartzsite. We are signed up. 200 ah of lithium will definitely get you through the night with your fridge. A standard 12v deep cycle is 88 amp, 44 amp hr usable. So, that would be like having 4+ 12v deep cycle batteries. The other advantage - they charge much faster. Not knowing which converter you have, it is hard to say. A few years back Keystone switched to one capable of charging lithium. We use two Honda 2000’s as backup to our Super Solar. Lithium batteries are great, even without solar. Good luck.
