I use several ATSs (automatic transfer switchs) to connect my off-grid solar to the house. When the PV -> battery charges up enough to turn on the Inverter - the Inverter power flips the ATSs from grid to inverter. When the batteries run down and the inverter goes off, the ATSs automatically switch back to grid.
At the main panel, I have a 50a@240v ATS + a 10 circuit MTS (manual transfer switch) combination for general circuits / load control. The MTS let's me choose which circuits are 100% grid if I need to lesson the max load on the inverter. A dedicated 12,0000w AIMS inverter feeds this ATS - which is 50a@

i love this idea, would like to know more about it.
