I'm a busy old guy overwhelmed by prepper projects, food needs etc. I need to buy my solar components and wait my turn for delivery, presumably months out, to install an off grid system for our 1600 sq ft home. (Just my wife and I.) The energy audit is problematic because we purchased the property in Jan 2021 but did not occupy it until Aug 2021; All those months the house was empty and the 3 ton heating/cooling ran at bare minimum. The kw PV system we need I estimate is between 12 and 18. I'm hoping to use >400W Q cell (?) panels (12) on my garage roof which will hold that number perfectly. (Because the house roof is partially shaded.) Both roofs face mainly south/SW. I am comparing EG4 Lithium batteries 25.6V (24V) 5.12kWh ( x 2 inverters?) or Bluetti system AC 300 or 500 with 2 inverters for a 240V system to support our heating/cooling system. Quality and longevity of components is a must. I will not be feeding excess power to the grid we are on because here in Tennessee the payback is minimal. My purpose is driven by grid down, not pay back. My son would help me install the system and I will have a qualified electrician inspect it before operation. Can anyone here help me with my shaky assumptions and direct me to the most practical choice of components?
