My solar is an emergency back up,Keep food cold, water flowing and communication up,essentials only, not comfort. Home is only 2 brm., 800 sq ft.,System Not tied to pannel, comes through wall next to back door ,have double Recepticals so no cords through the windows, when power go's down I just run cords from recept. to appliance. My water is direct tied to 12volt via fused switch,city water runs through 300 gal emergency tank to RV pump and can switch from direct city preasure to tank via manifold. I think I am going to double my water storage capacity.I run the water system 2 or 3 days a week to keep water fresh.I am going to direct tie to fridge & freezer taking them off gridd , just haven't felt like crawling under my home yet.
