Might be time to jump on here and make a thread about my solar with battery back up.... but to answer the battery question asked above: I like simple phi lithium iron phosphate battery’s. Three of them make 10.5kw. At 10,000 cycles and built in BMS they work great for load shifting and back up. I paired it with a Schnider xw+ so I could ac couple to my grid tied inverter. If I did it again I would look long and hard at Sol-ark for its many more features and modern design.
