[RE-wrenches] Increasing output Amps, Off Grid

[Jeremy Rodriguez]

Hello
I don't think an OB Radian can be added to an existing stacked pair of FX's. At least easily and have all three inverters work happily with each other. Can it?

My client is wanting more output. Even if it's just one leg of 120/240. He is planning to wire a circuit to an outbuilding. 120 v only is fine. He has overloaded the dual 3648 set up once before.  I recommended another pair of FX3648 inverters with autoformer. 
Comments and recommendations appreciated. 
Thanks in advance
