I recently bought an MPP Solar LV 5048. It's hanging in the barn waiting for me to build my battery and hook up wires. Unfortunately, the manual is completely useless as far as explaining how the unit should be connected with the existing AC.
I live in "Hurricane Alley" and also "Lightning Alley" so goal #1 is to have capable backup power when grid power goes down which it does frequently. We were out for 2 weeks after Irma. Secondary goal is to run as many base loads as possible while the grid is up.
I have a 200A main service panel at the house which feeds a 100A sub-panel in the barn. Solar, battery and inverter will be at the barn.
This unit supposedly has an "internal automatic transfer switch". I'm not sure if that's true, but it does have AC input and output and can be configured for battery priority or line priority. I just can't wrap my head around how to connect the AC inputs and the AC outputs to my sub-panel in the barn. I'd like to do this hard wired and also prevent any chance of feeding back to the grid. What will I need in order to do this safely and effectively? And would I still be able to power some circuits in the house or would I be stuck only powering barn circuits?
