Friends:
I am hoping y’all can tell me I am doing something wrong with my arithmetic. I have registered to purchase Blue Planet batteries and priced the product. I come up with math that indicates that comparing usable amp/hours to usable amp/hours, that the Blue Planet is 5 times the cost of a flooded L-16 battery array on a cost per kilowatt/hour. Can this be true? I am using these parameters: 1. DOD for flooded L16s: 50% 2. DOD for Blue Planet: 100% I hope I am wrong. Also, we often install battery arrays that are upwards of 4,000 AH. For example, we installed 5,668 of East Penn flooded batteries on a couple of projects. To acquire the same capacity in Blue Planet would require 9 cabinets (again 50% DOD versus 100% DOD). Is this correct design? Is it practical to install 9 cabinets? Does the system detect and compensate for circulating currents in this many parallel strings? Thanks in advance.
