      It works great, my electric company switched to peak billing so this is used to power my entire office to save on my electric bill. Then it's charged up during off peak when power is cheap. It runs several servers, desktops, firewall, monitors and window air conditioner during the summer. Once it it warms up again I plan on hooking up solar since it includes an mppt controller. Also, had a few power outages and this didn't skip a beat, it was nice not having to start a gas generator. This is the power cord https://www.amazon.com/dp/B07QYR9C9K used.

      Everything arrived in separate boxes a few days of each other. Putting it together was easy, just followed the manual. Has a lot of power and can easily be wheeled around when needed.

      It's picky with the solar panels it can use. Charging off a generator is a royal pain in the well. Otherwise it works

      Firstly, excellent product, would buy again BUT setup is not push button or simple. It does NOT come with a power cord, nor does the company sell one… but you can use any generic one you can buy online and it works wonderfully (they do this to make it cheaper, so I get it…). You also have to assemble some high voltage batteries which is more involved than some people are probably expecting but honestly very simple.

      Would not recommend for somebody wanting push button setup, this is a great product for people who know what they are doing..
