Best way to use two AC200’s

Is anyone using two AC200/p’s, one feeding the other? Experiences? I just wonder how well this could work, with each having its own 700watrs of solar input.

The most efficient way would to split your load up more or less evenly on each and run them separately. If you chain them together and have one charge the other while running load off the one being charged, then you will loose 30% efficiency between battery recharge and inverter for the power from the charging AC200P.
