so i have a small ac
pump plugged into a ac timer plug into a 200 watt inverter connected to a battery charge controller to a deep cycle battery,which is connected to a 45 watt solar panel. this works great for off the grid gardening. the cost $450.00 holy cow !!! this is not cost effective compared to 12g wire and a gfi outlet. but it does work good.(i collected my set up for free) so i hope this helps ,andy
