well i am looking to buy a suit case solar system from renolgy.
not done any solar before. so not sure if this is a good deal or not.
$280. new in box. $220. open box. refurbersed aka someone elses problems.
There are a few things to consider; I will attempt to discuss them without muddying the waters further.
refurbs
I buy refurbs whenever possible and have had great luck with them. They are not necessarily someone eles's problems. As long as there is a return policy a refub is probably a good buy.
100w
Here is
what people are doing with 100w here on the forum. You can compare this to what you want to do.
suitcase panels and controllers
Full disclosure: I am not in love with suitcase panels. IMO they are expensive and rather bulky for the power they put out, but I'm probably not the target audience.
Renogy sells two versions of the 100w suitcase; one has a
charge controller built in and the other does not. I am assuming this one has the controller built in because the original price lines up with that version.
The good news: you wouldn't have to buy a separate controller.
The bad news: on the panel is an inefficient place to put a controller. The best place is next to the battery that is being charged. This has to do with voltage drop between the controller and battery.
If I were spending $220
Based on
my [needs/preferences/storage], if I was spending $220 I'd get two 100w poly panels and a cheap-but-configurable 20A shunt controller.
bottom line
It will work; it won't work super great. Worst case scenario is if you outgrow (or get frsutrated with) it you can resell it to someone who is looking for one.
