After doing a whole lot of homework, and getting several recommendations and quotations, I decided to trust the folks at Cosuper with my domestic installation of a 5kw solar inverter in China. Outstanding delivery from beginning to handover. All went precisely to plan and as promised. The components and workmanship were first-class. The system performance is excellent and I love looking at the App that gives me live feedback on what power is produced, what power is being used, and what excess is directed to my batteries (along with lots of other useful info). The tools provided allow me to better manage my energy consumption and minimize my power bills. Thanks to Melisa and her team for making all this a reality and exceeding my expectations.

Friendly and efficient service plus quality workmanship. Really happy to have chosen Cosuper all-in-one solar charger inverters to upgrade my older system.

Cannot help but recommend Cosuper, Melisa, and her crew. All top-of-the-range panels and inverter selections went really well and now I learned how to choose right inverter and battery.
