No critisisms at all,nice small setup! I LOVE small solar,and as Tes points out,anybody can do this,its not difficult to set up and net has a 1001 sources with pictures to walk you thru,dont need to be an electrician.

But I do like having a small generator in addition.Just a 2000 watt (1600 continous),with extension cords can rotate appliances and keep refer and freezer cold.

And during the run times so you dont try to run 24/7,charge the batteries for night use.

This sounds silly but I had neighbors whose food rotted in refer and freezers,and snow was on the ground,just move it outside,some folks never thought of that.
