Hi Chris For an off grid system a 200AH 12 volt battery is rather small without resorting to parallel strings.
Three strings is only 600AH which is still on the small side, so one might ask why the 8K inverter? The OutBack cabinet is fine for a back-up grid-tied system, not really a full off grid house Without starting a big discussion, I would stick to a single series string sized to the load for three days autonomy. 200AH is usually a rather small weekend cabin and 600AH would be a smaller medium sized house.

I have a 8KW Radian system for which I am considering Rolls Surrette or Outback 200RE AGM batteries. I know people like the Surrettes, what is the experience with the outback battery system? -- Chris Mason
