Love it!!

Super fast shipping and customer service is great. One charge lasted all weekend on its first camping trip. It’s not too heavy which is a plus. We also tried it with high watt kitchen appliances and our small washer. After 3 wash loads it went from 99% to 93% (video is during wash cycle). Very pleased with this investment

Setup couldn't be simpler

After watching the video about connecting panels in a series and reviewing the short user guide, setup was really simple. My generator is being charged by the sun as we speak. Later today, I'm going to plug in a few appliances and see how long the charge lasts for us. So far, thumbs up! (Can't post pics because I have a really old/bad cell phone. Sorry!)

Mr.

Great kit. If anything constructive criticism wise, I would suggest someone review the orders to ensure they make sense. I ordered 4 solar panels and only a duel cable splitter....had to go back after delivery and order a quad cable connection. Other than that it was extremely easy to set up and get going. My garage freezer and refrigerator are now permanently off-grid and I have portable power in an emergency! Great stuff!!!
