How does a balcony power plant work?
Our balcony power plant offers a simple and efficient solution for generating your own electricity. It consists of four ultra-light solar modules, each with a capacity of 200W, and an HMS-800-2WB microinverter with built-in Wi-Fi. Installation is quick and easy: The inverter is mounted on the solar panels, connected using solar connectors, and then the AC cable is plugged in. Your home’s electrical system primarily uses the solar power generated. If needed, additional electricity is drawn from the public grid. You also have the option to add a battery system to store excess energy and ensure nothing goes to waste.
