I actually just started building my solar mining shed. I already had the shed. I bought used panels and a used l3+. I think the l3+ uses around 1000w. Initially I bought the set up to power my well when the power goes out, but decided to take different route. So, instead of returning the inverter I decided to mine since I've been putting it off for a couple years. Right now I have an lvx6048, 4 x100 amp batteries, 6000w of panels. Its not running yet. I look at it as a hobby and investment. Hobbies aren't cheap and you have to look long term with investments. The ROI at today difficulty rate is around $175 - 200 monthly with this one rig.
