I have been running my Endless Breeze fan (A portable version of the Fantastic fan made by the same company) all day long for over a month now. It often runs for a couple hours in the evening when I get home as well.
I am using a 100w solar
set up and a group 29 battery (120aH). I have no want for battery power for lights
or water pump etc each day.
Keep in mind, I am stationary and have no other way I charge my battery.
I could use a charger when I run my generator
, but I just don't need to. You should be fine with an average charging system.
