I'm new to solar tech, and bought this combo as we have a mini camper and want to be able to power things when we do not have any electric hookup.
Tested out the panel on a normal day in May - not too bright but not dull. I was pulling 92Kw/h from the 100w panel - which is fantastic!
I haven't discharged the battery yet - need to drain it down and charge it up to properly initialise the battery - but it is all good now.
Don't forget to charge the battery using the mains first - leave it for 12 or so hours before using it with solar or it doesn't show the solar panel as working. Once done, it works perfectly.
Powered a mini-fridge off of it, with it being topped up with solar! The mini-fridge pulls 40-50w/h - so about 7-8hours off the battery.
