EcoFlow Delta Pro 3 Kit with 400 Watt Solar Panel….Worth It!
September 24, 2024
I was on the fence on the viability of portable solar power systems and how it compares to portable gas-powered systems. Did some extensive research and looked at reviews on major manufacturers like EcoFlow, Jackery, Anker, etc. Finally decided to take the plunge and purchased a EcoFlow Delta Pro 3 kit with 400 watt portable solar panel. Best investment I’ve ever made! The kit was a bit on the expensive side, but Earthtech Products offered an excellent deal I couldn’t pass up. This solar generator is a monster with 4096 kWh on tap and 120v and 240v connections. It powered several of my large and small appliances including a full size refrigerator, portable a/c etc. without issues. Only complaint I have is it is a bit on the heavy side at 113 lbs. but the wheels and telescoping handle helps a lot. Highly recommended!

Are the 400watt panels portable? Does a connector cord for the portable panels to Pro 3 come with? Is this bundle in stock ready to ship ?
1 Answer
Yes, the 400 watt panel in this kit is foldable and portable. It includes an 8ft solar charging cable and is currently in stock. Solar extension cables are also available if you need a longer distance between the panel and power station. Thank you for your inquiry!
