OutBack is introducing the first deep cycle front terminal rack mount batteries to the solar industry. These batteries and enclosure install more easily and in less space than other rack-mounted solutions. As sealed AGM batteries, they require no electrolyte maintenance and are made for both cycle and float service. The large capacity of these batteries reduces the number of parallel strings required to serve a stand-alone or backup power system. These are rated for 600 cycles at 80% depth of discharge, and 1,800 cycles at 50% depth of discharge. The protected front terminal cable attachment allows safe, easy, space efficient installations. One bus bar is included with each battery and is used to make series connections between side-by-side batteries. Made in USA.
