Feature: 1. High in Safety: The solar grid micro inverter can independently control each component in parallel, largely improving the safety. 2. Reliable Using: Built in high accuracy instrument allows you to better check the working status of each component, very simple. 3. Efficient Work: Maximum power point tracking can be achieved to maximize the overall output power. 4. Better Control: Can be operated and monitored through WiFi or mobile APP, which greatly improves the overall working efficiency. 5. Easy to Install: Can be installed directly behind the module or on a bracket for easy maintenance, very reliable and practical.
