This client came to us equipped with a Goal Zero Yeti 400 Portable Power Station, a Zamp 100W solar panel, and a 30A Zamp charge controller. Her primary use for the Yeti 400 Power Station was to power her CPAP machine, which she was able to do for about 2 nights before it needed to be recharged. She used the Zamp solar system to power her refrigerator, but 100W wasn’t enough to keep up with the refrigerator’s power needs. We upgraded her solar system to 260W using a Zamp 170W panel, and a Zamp 90W panel, which we bolted together using two angle aluminum bars. We installed a conveniently placed outlet for her CPAP machine, which is now powered directly from her house batteries, along with her refrigerator. Now she has a solar power system that meets her energy usage needs without the worry of charging the Yeti 400, or her food getting warm.
