I bought a kit from them to run my well pump and it works good. It was a basic kit with 400 watts of panels and an mppt controller with all the wiring and fuses. Two 200Ah batteries and a 4000 watt split phase AIMS inverter. Everything came as promised except I was supposed to get 4/0 AWG and they sent me 1/0 AWG for the batteries and 2/0 AWG for the inverter. After going back and forth they credited me some of my money back and I got the Proper cables myself. At the time I could have beaten the price of their kit, but not by much. In the end they did make it right and I was okay with that. Service means a lot these days and I would buy from them again if the price was right. Everything was brand new and undamaged when it arrived at my house also. I have since added another battery and more solar to this kit myself because...why not! lol
