Features 1GRID CONNECTED INVERTER: Micro inverter can independently control parallel components to minimize safety hazards. Pure sine wave output ensures stable and pure output voltage which can adapt to almost all load appliances. 2MPPT FUNCTION: Micro inverter has two independent MPPTs which can achieve maximum power point tracking and maximize the overall output power. 3EFFICIENT WORK: The inverter is equipped with high precise gauge allowing you to see the working status of various components. Can be operated and monitored through WiFi or mobile APP greatly improving overall efficiency. IP65 waterproof safe to work outdoors. 4SIMPLE INSTALLATION: Standard input port simple and secure connection. Integrated AC output port can easily connect more machines to increase system power and connect to the power grid. The micro inverter can be installed directly behind the module or on a bracket for easy maintenance. 5MULTIPLE PROTECTION: Inverter automatically stops output in case of power grid failure or power outage and also has overheating short circuit overload voltage frequency temperature and current protection etc. highly safe and reliable.
