Would this be a good product to use on a daily basis for a remote office? I have a small building and would like to convert it into an office. So I would need continuous power for a laptop, mifi device, a lamp or two (for evening hours only) and perhaps a small space heater (not continuous - just a little to take the chill off). I was thinking I could position and secure the solar panels on the roof, drill a small hole to bring in the cords to store the Yeti indoors. Interested in your thoughts! Thank you!
